Johnson Department: Landscape Architecture and Environmental Planning The landscape plant materials informational needs of planting designers were evaluated in a historical and contemporary context. It was found that plant designers need to know about the environmental and cultural adaptation, landscape value and use, and commercial availabil ity of the plant materials that they use. Surveys of regional plant materials experts and nursery inventories were made to determine which plants should be included in a reference text . The climate of the region is also identified and compared to other parts of the country. Plant materials reference books were reviewed to see if they provided this information for plants grown in the Intermountain region. These reference books were found to be inadequate for professional landscape architectural use in the region. , ix A proposal for a plant materials reference handbook is made and individual plants to be included are selected. (204 pages) CHAPTER I THE INTRODUCTION The study of plants has been a traditional pa r t of the discipline of l andscap e architecture. The effectiveness of a l andscape architect's planting plans are dependent upon s everal factors. These include the s el ection of plants and their or gani za t ion and placement i n the lands cape. In order to make intelligent de cisions about plant materi als, (p l ants selected for specific landscape uses ) landscape archi tects, horticulturists, and other professionals with planting design i nterests must be familiar with the characteristic s of the plants from whi ch he or she will make choices . Th is need for famil- iarity is ampli f ied by Hubbard and Kimball (19 45, p. 153): The characteristics of plants, over which, as we have seen, t he lan dscape architect has little or no control, have i n e vitably a great influence on the effect of any design in which vegetat i on is used a s a material. The forms, color s , and text ures offered by plants give to the designer ce rtain opportuniti es, but also they set for him certain l imits. The natural character of each plant, and t he asso cia tions in which, in most men's minds cling to certai n plants, give a plant a complex individuality, and make i t by no mean s an easy thing to use in esthetic compos ition. The understanding of these characteristics of plant materia l constitutes no inconsiderable part of the s kill of t h e landscape architect. Indeed, it is special knowledge like this which differentiates the l andscape architect from other designers. It has become expected that landscape architects or horticulturists w~l know the envi ronment al and cultural adaptation, the 2 potential lan.d scape val ue a nd use, and the botani cal characteristics of a wide range of plant ma terials. The most accurate knowledge and understanding of the chara cte ris tic s and capabilities of plants comes from continual observation of the m unde r diverse growing conditions and in a variety of uses. The writing and observations of others are helpful when they are avail ab le , h owever, it has been the opinion of this author that adequate r e fer ence materials on plant selection and use in the Intermountain region (centered around the Salt Lake City, Utah and Denver, Colorado metropolitan areas) does not exist. The intent of this thesis is to examine the validity of this supposition. The Pr oblem Statement The premise that no adequate reference literature exists on plant materials for use by Intermountain landscape architects has been broken into several parts for examination in this thesis. basic assumptions have been made. Two The first is that planting designers need descriptive information on the environmental and cultural adaptation, the potential landscape value and use, the and the botanical morphology of the plant materials avil~ty, that they use. The second assumption is that the available plant materials literature is not adequate for professional use in the Intermountain region. This thesis will evaluate the informational needs of landscape architects in the Intermountain region. It will also review the available plant materials literature to determine if it meets these information needs. 3 The Research Process The thesis will be divide d into several sections. The first section (Chapter II) will begin with a review of the literature tracing the history of man's developing appreciation and knowledge of the usefulness and limitations of plants. This review will provide a historic perspective for establishing informational needs including descriptions for individual plants concerning (1) environmental and cultural adaptations; (2) potential landscape value and use; (3) availability; and (4) botanical morphology. The second half of Chapter II will use the information criteria from the historical review to evaluate the available recent literature used by landscape architects as plant materials reference handbooks. These books are used by planting designers for specific information about the expected performance or usefulness of individual plants. This review will be conducted to determine the adequacy of these reference works for professional use in the Intermountain region. The review will examine each work in five informational categories. The fir~t three, suggested by the first half of the chapter, will include the (1) discussion of the environmental and cultural adaptation of individual plants; (2) potential landscape value and use; and (3) botanical descriptions. The review will also examine the: (4) intended audience of the reference work; and (5) geographical orientation of the work. Plant materials reference handbooks that would be suited for use in the Intermountain region must include the plants adapted to 4 the region. Chapter III reports the results of three surveys made to identify the Intermountain regional climate and the plants adapted to it. The first of these surveys will define the region, giving it a climatic, environmental and geographic context. For this thesis, the climate of the region is important only as it effects the potential growth or usefulness of plants. Therefore, the description of the climate of the region will be presented in rather general qualitative terms from interpreted reports of other researchers. The second survey will be conducted to determine which plants should be included in a plant materials reference text for the Intermountain region. Selected landscape architects, horticulturists and other plantsmen of the region will be surveyed to determine which plants they believe to be climatically adaptable, commercially available, and useful in Intermountain landscapes. A third survey will be made of selected Intermountain nursery catalogues and West Coast suppliers to determine which plants are part of regional commercial inventories. Chapter IV will review the stated hypothesis and evaluate it in terms of the literature review, the review of recent plant materials reference books and the surveys of regional climate, plant materials experts and nursery inventories. From these evaluations, a deter- mination about the validity of the basic assumptions can be made. If it is found that there is insufficient information existing (that the assumptions are true), recommendations for providing adequate information will be made. The last section will review potential further research, identifying apparent gaps in existing information. 5 CHAPTER II LITERATURE REVIEW The literature about plant materials is quite extensive and diverse including books on biology, plant morphology, taxonomy, physiology, pathology, agronomy, horticulture, landscape management, planting design, propagation, and many other academic and popular works. No attempt has been made to make a comprehensive review of this literature. The purpose of this chapter is to investigate two subject areas; the historical /association of men and plants from prehistory to the present day, and plant materials reference books currently available for use by landscape design professionals. The first section is intended to show how man's desire to know about plants has developed. It will trace man's growing appreciation of the potential uses of plants and the development of an understanding of the responses of plants to their environment. It is not intended to be an exhaustive study but rather to create an appreciation of the / evolution of information to meet the needs of today's planting designers. The second section of this chapter will look at current reference books to determine their applicability to the Intermountain region. These reference books will be evaluated in terms of the information needs described in the first part of this chapter. 6 Historical Associations Man has been associated with plants from the beginning of time. A concomitant relationship between Man and plants is illustrated by the Judeo-Christian concept of creation--Man placed in the Garden of Eden. Historians (Berrall, 1966; MOrris, 1972; Newton, 1971; and Tobey, 1973) have postulated that the earliest peoples were fruit, nut, and animal hunters and gatherers. Later neolithic man developed a primitive sedentary agriculture, domesticating animals and cultivating plants. The "Fertile Crescent" civilizations of 7000-4000 B.C. used plants not only for food but also for fiber and building materials. The Mesopotamian civilizations of 3000-331 B.C. used plants for gardens and parks as well as a source of food and fiber. Figure 2.1 (see page 7) is an artist's conception of the fourth century B.C. Hanging Gardens of Babylon. In other parts of the world, emerging societies have had similar developments in agriculture. Between 2000 B.C. and 1200 A.D., the Hohokam and Anasazi Indians of southwest North America developed fairly extensive irrigation- systems for their agriculture (Farb, 1968). Plants provided not only food, clothing, buildings materials, and shade for parks and but they were also used by some g~rdens; cultures for medicines or for religious ceremonies. McHarg (1969) describes several pantheistic cultures where man's use of plants and respect for nature was considered a ritual of reverence and his relationship to his world was sacramental. ~ 7 Figure 2.1. Artist's conception of the Hanging Gardens of Babylon. (Source: Berral1, 1966, plate 14) Figure 2.2. Physic and cooking herbs in a monastery cloister garden. (Source: Berra11, 1966, plate 61) 8 As early as the second century B.C., plant materials were considered an essential decorative part of the country residences of Roman nobility. Pliny the Younger's description of his Laurentine Villa (Plinius Secundus, undated) includes not only a discussion of the climatic orientation of the architecture and its relationship to conditions of the site, but also a horticultural appreciation of the planting around it. Pliny and his father were two of the earliest horticultural writers. Around his Villa, Pliny observed the growing conditions that plants were exposed to and was able to identify which plants grew well near the seashore and which could not tolerate the sea spray. This represents one of the first written documentations that plant materials be selected for specific microclimatic and environmental reasons. Such recommendations have remained an integral part of most plant materials literature. During the eighth through the fourteenth centuries A.D., classical thought and literature from earlier periods were preserved by monasticism. From the intellectual endeavors of the monasteries came further development of horticultural practices such as the growing of vegetables, fruits, nuts, and physic plants (medicinal herbs). Figure 2.2 (see page 7) shows a monastery cloister garden. Also developed during the Medieval Period were the castle gardens which were planted within the castle walls to provide vegetables, spices, physic herbs, and visual relief from the cold, cramped, confinement of the fortress (see Figure 2.3, page 9). Charlesmagne's Capitulare was a plant list developed to recommend plants for use in the castle garden and it became the main reference turned to by monasteries, kings, and lords of the Middle Ages (DeTurk, 1968). Figure 2.3. Artist's conception of a medieval castle garden. (Source: Berra11, 1966, plate 67) Figure 2.4. Trees and water featured in MOorish gardens of the Alcazar in Seville. (Source: Berra11, 1966, plate 43) 10 While most of Europe was in the grip of the Dark Ages, the Moors had developed elaborate landscapes in Spain (Newton, 1971). In this harsh climate, plant materials were used to provide shade and visual relief and they were watered with elaborate irrigation channels (see Figure 2.4, page 9 ). During the Renaissance in Europe , garden design developed as a disciplined art. The Renaissance began in Italy in the fifteenth century, moved into France in the seventeenth century and then England in the eighteenth century. Although Renaissance gardens had been intended to provide aesthetic benefits, the designs of Claude Mollet and Andre Ie Nortre elevated the garden to a position of aristocratic ostentation. Trees and shrubs were selected for their visual characteristics and for their adaptability to the specialized horticultural practices of topiary, pollardy, pleaching, and espallier. The trained plants took on rigid geometric and architectonic forms (see Figure 2.5, page allees. l~ as labyrinths, knots, parterre gardens and Plant selection and literature on the subject during this period emphasized the plant's ability to adapt to the rigorous cultural and maintenance techniques of the period. The "Gardenesque School" of landscape design developed in England through the work and writings of Humphrey Repton, Lanceolot "Capability" Brown, and J. C. Loudon. This movement was a direct contrast to the English Renaissance styles. Planting designers were now interested in developing a natural landscape (see Figure 2.6, page 11). Even the popular newspapers, The Spectator and The Guardian advocated the new style of natural gardens (Newton, 1971). 11 Figure 2.5 .

English gardenesque style landscape at Stourhead. (Source: Utah State University Department of Landscape Architecture slide library) 12 The gardenesque style was popularized in the United States through the writings of Andrew Jackson Downing. Downing's writings were partially responsible for the tremendous increase in general public popularity of landscape gardening. As public interest grew, so did the demand for more arid different plants as ·well as "how to do it" references. The result was the collection, importation, and cultivation of exotic plant materials from allover the world. popular literature such as Waugh's Landscape Gardening (1899) was written to describe the potential visual characteristics of primarily exotic and horticultural hybrid plant material. The growth of landscape architecture in the midwest at the turn of the present century saw a shift in attitudes away from the ideals of Brown and Downing. The work and writings of Fredrick Law Olmsted, Sr., Wilhelm Miller, H. W. S. Cleveland, and O. C. Simonds began to show a much deeper understanding of the indigenous landscape of a region. In 1913 Miller stated, "The way for every new country to come into its own is to apply universal principles of design to the native materials" (Christy, 1976). These ideas were later echoed by Jens Jensen who "carefully noted plant sizes, forms, textures, colors, growth rates, successional patterns, and plant associations" (Johnson and Becker, 1976; · p. 54). Jensen made it clear that land- scape designs should not be considered "natural" just because plants were used in the styles common to the English gardenesque idiom. Instead, as Jensen described it, the plants must be used in plant associations . to provide a successional landscape that was responsive to ecological principles (see Figure 2.7, page 13). 13 Figure 2.7. Prairie landscape style of Jens Jensen at St. Louis, Missouri. (Source: Gerald Smith) Figure 2.8. Plants used to reduce undesirable noise, exhaust, and headlights of passing automobiles in front of homes. (So urce: the author) 14 Henry V. Hubbard was another early twentieth century landscape architect who advocated a better understanding of the materials that landscape designers worked with. In his classic design textbook, An Introduction to the Study of Landscape Design, (Hubbard and Kimball, 1917, p. 3), he synthesizes many of the earlier expressed ideas: The landscape architect should know the materials of his art: ground forms, vegetation, and structures in their relation to the landscape. He should know on the one hand what results are physically possible of accomplishment with these materials, and on the other hand what kinds of beauty these materials can best produce, and what kinds of beauty were better attained in the materials of some other art. Since, for the most part, the landscape architect cannot produce at will in his design all of the forms which he might desire, but must choose from among the forms offered by nature those which will suit his purpose, he cannot be confident that his design is possible of execution unless he possesses " an accurate first-hand knowledge of plant materials and of the ground forms from which he must choose the elements of his composition. Since the beauty of vegetation is that of intricacy, of multiplicity, of growth and change, the landscape architect's experience and power in design will come to be quite different from that of an architect, who deals with definite, rigid forms and balanced masses. Hubbard further explains that because plants are alive and constantly changing, the planting designer must be familiar with their character from season to season and throughout their life span from juvenility to maturity and senescence. of plant materials as a environment. f~nctio He deftnes the indivi.duality of two factors: inheritance and The inheritance is "its racial tendency to assume certain typical characteristics • • • " and its environment includes" • • • the soil and moisture conditions, the climate and air conditions, the wind, Slul, and exposure." The form and character of the plant are the result of its inherent potential and its external surroundings. 15 Florence Bell Robinson develops these ideas much further in her writing. Her Planting Design (1940) textbook is divided into sections, the first being the "Design Factors" and the second being "Ecological Factors." She describes design factors as being the visual attributes expressed by the plant--its color, texture, and form. The ecological factors section discusses selecting materials according to their probable response to soil, climate and microclimatic influences. More recent writers (Crowe, 1958; Daubenmire, 1959; Eckbo, 1956; Rubenstein, 1969) also express the need for the plant designer to know the environmental capabilities and limitations of the plants they use. Daubenmire, a plant ecologist, systematizes the environ- ment into factors. major categories: These factors " may be grouped into three (a) climatic (or aerial), such as rainfall and air temperature; (b) edaphic, such as soil moisture and soil temperature; and (c) biotic, such as parasitism and herbivory." Recently interest has shifted away from the ecological and cultural adaptations of plant materials and is now directed towards determining the potential of plants to provide very specialized functiqns in the landscape. by earlier writers. This was implied but not fully developed Several writers (Carpenter et aI, 1975; Colvin, 1970; Hackett, 1971; Johnson and Becker, 1976; Laurie, 1975; and Robinette, 1972) have summarized the findings of a number of researchers who are determining some of the special uses of plant materials. These special uses can be divided into five groups: (1) architectural uses; (2) engineering uses; (3) climate control; 16 (4) aesthetic uses; (5) other uses. Figure 2.8 (see page 13) shows some engineering uses of plants. This review of some of the historical a ssociations between plants and peoples has been conducted to document t he development of man's appreciation for the potential uses that plants have. These relation- ships have been summarized on a time line in Table 2.1 (see page 17). The intent has been to show what people have learned about plants that allows them to use plants to create more beautiful and useful planting designs. This discussion has shown that it would be useful for landscape designers to have a good reference handbook t hat classifies plants according to: (1) their potential response s to identifiable environmental conditions; and (2) their potential to serve various utilitarian or aesthetic landscape functions . This kind of plant materials handbook would be useful in determining if a plant can be used for a special landscape effect or whether or not that plant is adapted to a specific microclimatic environment. Contemporary Reference Literature A survey was made of contemporary plant materials reference handbooks to determine wHat type of information was presently available. Based on the assumptions outlined in Chapter I of this thesis, and the findings of the first part of Chapter II, each book was evaluated using five criteria. 1. These include: Discussion of the environmental and cultural adaptation and requirements of individual plant materials; 17 10,000-7000 B.C.

Each book is evaluated for its contents and each of the five above criteria are marked to show the contents of the book. If the author has included a discussion on the issues of a specific criterion, that criterion is marked with an "X." If the author only makes a few comments about a given criterion, then that criterion is marked with an "D." Any pertinent remarks about the book are made in a remarks column on the matrix. first author only. Several multi-author books are cited by the Full literature citation for each book can be found in the Literature Cited section at the end of the thesis. A review of the completed matrix shows that most of the authors that intend for their work to be used by design professionals include information on the environmental and cultural adaptation, and the landscape value and use characteristics of plants. The matrix shows that the idea of a plant material reference source for landscape design profession.a ls based on the specific characteristics of plants 19 in a given geographic region is not a new one. However, at present such a comprehensive reference for professional use in the Intermountain region is unavailable. A number of authors (Feucht and Macksam, 1968; Harrington, 1954; Holmgren, 1948; Huddleston and Hussey, 1975; Johnson, 1970; Kelly, 1957, 1970, 1975, and 1976; Shaw, 1963; Sunset, 1967; and Sutton, 1974) have made contributions towards developing reference handbooks for landscape design professionals in the Intermountain area; however, their work is not comprehensive. Either their plant lists are too limited, their discussion of plant environmental adaptation is limited, or there is insufficient botanical information to identify specimens in the field. Further evaluation of the comprehensiveness of some of these books is included in the matrix of suitability of selected plants for use in the Intermountain region included in Appendix A of this thesis. The matrix shows which individual plants are listed by Intermountain plant materials authors. Table 2.2.

The first survey was a review of the physiographic nature of the Intermountain region. It delimits the survey area boundaries and describes the geomorphic, vegetative and cultural framework of the region and then characterizes the climatic and environmental factors of the area. These characterizations will be somewhat generalized because extensive contrib~s of a number of authors (Callendar, 1966; Cronquist et aI, 1972; Dudley et al., 1974; Hunt, 1967; Jeppson et al., 1968; Kelly, 1957, 1975, and 1976; Nelson, 1969; Sunset Editors, 1967; United States Department of Agriculture, 1972; and United States Geological Survey, 1970) towards documenting the nature of the Intermountain climate are readily available. Within the scope of this thesis there are two reasons for describing the climate. First, to show the general effects of the climate on plant materials, and second, to compare Intermountain climate with the climate of other portions of the country. It is important to determine if plant materials reference handbooks written for other parts of the country would be suitable for professional use in the Intermountain region. 24 The purpose of the second and third surveys described in this chapter is to determine which specific plant materials are suited for landscape use in the Intermountain region. The survey was broken into two parts--a survey of the opinion of Intermountain plant materials experts, and a survey of Intermountain nursery inventories. The Intermountain Climate The theme of George Kelly's writing (1957 , 1975, and 1976) has been that horticulture in the Rocky Mountains is different than horticulture in other parts of the country. Kelly defines the Intermountain region as an area with a diameter of " . • . approximately a thousand " miles . • . centering near the southwest corner of Wyoming • covering portions of MOntana, Idaho, Oregon, Nevada, Utah, Arizona, New Mexico, Colorado, Kansas, Nebraska, and the Dakotas. For his discussion of Intermountain flora, Holmgren (Cronquist et al., 1972) delineates a study area that is " • • . essentially the dryland region between the Sierra Nevada on the west and the Rocky Mountains on the east, and between the moist country of the Pacific Northwest on the north and the warmer drylands to the south." This region covers all of Utah, most of Nevada, north of the Colorado River in Arizona, southeastern Oregon and southern Idaho. For this thesis, the study area is more limited than either Kelly's or Holmgren's. The intent is to center it around the parts of the Intermountain region where the demand for landscape architectural planting design services is greatest, that is, the metropolitan areas around Salt Lake City, Utah and Denver, Colorado 25 (see Figure 3.1, page 26). Salt Lake City is the largest of a north- south strip of cities along the Wasatch Front stretching from Logan to Provo. Similarly, Denver is the largest of a north-south strip of cities along the Colorado Front Range from Fort Collins to Pueblo. These two metropolitan areas are the primary urbanized regions between the Midwest United States "and the West Coast. Although the climate of Salt Lake City and Denver are not exactly alike, the two cities are more similar than dissimilar when compared to the climates of other parts of the country. Boundaries for the study area should coincide with the natural landscape boundaries of physiographic provinces or climatic divisions. However, the use of exotic plant materials within "unnatural" urban environments often defies such classification schemes. Also the detail for such boundary identification is beyond the scope of this thesis and is left to the aforementioned authors. This study area will con- centrate around the Salt Lake City--Denver areas and therefore convenient boundaries will form a trapezoid whose corners are approximated by the location of Logan, Utah; Cheyenne, Wyoming; Colorado Springs, Colorado; and Provo, Utah (see Figure 3.1, page 26 ) • Although the areas adjacent to the study region will be similar in many respects, increasing "the size of the study area increases the amount of regional heterogeneity. There is a large amount of physiographic diversity within the physiogra~ study region. Hunt (1967) details the characteristics of five separate provinces making up the study region: (1) Basin and Range Province; (2) Middle Rocky MOuntains Province; (3) Wyoming 26 \ IDAHO -'"I;.=~ OGDEN I. / (WYOMING \ - ...... --+- BASIN AND RANGE / PROVINCE / ---........ -"J ) (. 1 / UTAH COLORADO COLORADO PLATEAU PROVINCE ARIZONA . \, FT • COLLINS \- ,DENVER \ \ ......... ____ ......... ~'COLRAD ) -,.=SPRINGS / MI DeLE (ROCKY '" MOl.NTA I NS __ ~VINCE, ) / '" "-~ \ ........ ~ NEBRASKA --l..J ? • \ p~: .I ___ VIN......

NORTH ~ STUDY REGION BOUNDARY PHYSIOGRAPHIC PROVINCE BOUNDARY Map of the Intermountain study region with physiographic provinces. (Source: Hunt, 1967) 27 Basin Province; (4) Colorado Plateau Province; and (5) Great Plains Province. Each province (see Figure 3.1, page 26) has a distinct and unique climatic character. The general environmental character of the region becomes the interfacing characteristics of all of the provinces. At the center is the Middle Rocky Mountains Province, which meets the Basin and Range Province on the west part of the study region, the Wyoming Basin to the north, the Great Plains to the east and the Colorado Plateau to the south. The two major metropolitan areas are situated on the outwash plains of the Middle Rocky MOuntainsSalt Lake City to the west and Denver to the east. Hunt finds that many of the landform features of the Middle Rocky Mountains and the Wyoming Basin resemble the adjacent provinces to the north and ,west. These provinces are characterized by great relief with many high peaks above 14,000 feet above sea level. The area also has shallow soils and a larger amount of annual precipitation than the other provinces in the study region. The Colorado Plateau has a flatter landform and arid climate with sparse natural vegetation. The Basin and Range Province is generally more arid and has sparser natural vegetation than the Colorado Plateau. The province is made up of numerous small parallel ridges and broad, flat valleys. The Great Plains Province becomes the eastern boundary of the study region. The major cities of the Colorado Front Range area are located at the western edge of this province on the outwash plains at the base of the Middle Rocky MOuntain Province. has gently rolling l~nd At this western edge, the province with deeper soils and more precipitation than the Colorado Plateau or the Basin and Range Provinces. 28 A review of the findings of several authors (Callendar, 1966; Jeppson et al., 1968; and Dudley et al., 1974) shows the climatic character of the region. The Intermountain region is characterized generally by extreme fluctuation in temperature, topography, and solar orientation. It generally has high winds, low humidity, low annual precipitation, and alkaline soils. limit plant growth. Any of these single factors can Together, they severely reduce the number of plants that a landscape architect may select from for his designs. The elevation in the Intermountain region varies from a low of about 4500 feet above sea level to greater than 14,000 feet. MOst of the large population centers, though, are at about 5,000 feet. The latitude of the survey area is about 39°N on the south side increasing to about 42°N on the north. However, the largest metropolitan centers of Denver and Salt Lake City are very close at 40 0 N and 4l o N, respectively. Diurnal temperature variation is quite high within the region. It is not unusual for 3O-40°F of temperature change between daily lows and highs. In Salt Lake City and Denver, the January mean temperature is about 20° while in July it is about 70°. Denver has about 120 freeze-free days annually while Salt Lake City has about 140. Cities north of them (Fort Collins, Cheyenne, and Logan) have fewer freezefree days. Precipitation is quite limited in the Intermountain region. The population centers get about 16-20 inches of precipitation in an average year. elevation. This amount varies with latitude, longitude and Generally, annual precipitation increased by moving south, 29 west or to a higher elevation within the region. Most of the precipitation comes during the winter (not during the growing season) and falls in the mountainous portion of the region. Of the 16-20 inches of annual precipitation that falls on Salt Lake City, only about six of it comes during the April-September growing season. This means that winter precipitation must be stored and applied during the summer as irrigation. Relative humidity is also much lower in this region than in other parts of the country, causing higher evapotranspiration rates. There is not as much variation, though, in the winter, as there is in the summer. Winds are quite high and variable in the region, further increasing evapotranspiration rates. Architectural wind loads of 90 to 100 miles per hour are not uncommon in the area (Callendar, 1966). Contential winds moving west to east are the major source of wind patterns in the region. Tropical storms from the southwest are the primary source of summer storms, while contential and maritime storm fronts from the north and northwest bring most of the winter precipitation (Dudley et al., 1974). As winds climb in elevation to pass over the mountains, they decrease in temperature and moisture holding capacity which often results in some precipitation. As the winds move over the mountains and down the east face, they increase in velocity, temperature and moisture holding capacity. This causes them to remove moisture from plant tissues which causes dessication within the plant. Because these winds are greatest in early spring while 30 activity within the plant is still quite low, the potential for severe dessication is high. Exposure to increased sunlight intensity causes problems for some plant materials not native to this region. Being at an elevation of a mile above sea level, the region does not have as much filtration of sunlight by the atmosphere. This will cause some plants (such as Taxus) to burn when used in sunny exposures. Soil in the Intermountain area is quite different from the soils of other parts of the country (Buckman and Brady, 1969). The soils of the area are quite shallow because of low precipitation, less vigorous natural vegetation, and relatively recent geologic activity. A lack of leaching activity in this arid climate has left them alkaline, many soils having a pH of 8.0 or 9.0 or higher, although most soils in the metropolitan areas have a lower pH. The high pH causes iron to be chemically unavailable to plants which often makes them chlorotic. The lack of moisture and therefore of high levels of biomass production has rendered the soils very low in residual organic matter which reduces fertility and makes the soil structure less desirable. Biotic influences on plant materials are different in the Intermountain region also. fungal disease problems There are generally fewer bacteriological and beca~ conditions in the region. of lower moisture and temperature There are also fewer insects but they can be devastating to plants already under environmental stress (Metcalf et al.,1962). A comparison of several climatic factors for five U.S. cities show the degree of variation in plant environments across the country 31 (see Table 3.1, page 32). In this table, Denver and Salt Lake City of the Intermountain area are compared with Sacramento of the West Coast, Columbus of the Midwest, and Philadelphia of the East Coast. All five cities are of similar latitude. Generally, the Wasatch Front climate is milder than the Front Range climate. It gets slightly more precipitation, has milder temperatures, longer freeze-free season, and fewer drying winds. For this reason there are more plant species that will grow in Salt Lake City than Denver. Ideal plants for the region then would be those that are tolerant to: . 1. low annual precipitation; 2. high diurnal temperature fluctuation; 3. low annual minimum temperature; 4. low relative humidity; 5. drying winds of high velocity; 6. high light intensity; 7. shallow soils of low fertility and organic matter and high pH. In ~ther parts of the country where soil, moisture, light and wind do not seriously restrict the use of plant materials, temperature is the limiting environmental factor. In those parts of the country plant hardiness is measured in terms of tolerance to annual average minimum temperatures. The United States Department of Agriculture (1972) has developed a map of plant hardiness zones based on annual average minimum temperatures. books by hardiness zone. Many authors label the plants in their Annual average minimum temperature is not Table 3.1.

Distribution of Soil Orders within the study region. (Source: United States Geologic Survey, 1970) 35 One of the reasons for reviewing the climate of the region was to answer the question: "Is this climate different enough from other parts of the country to require its own plant materials literature?" Kelly's answer is yes, and a short evaluation of plants growing here and in other places will confirm that answer. The probable ultimate height of several trees is specified differently by various wr~tes preparing reference material for different parts of the country (see Table 3.2, page 36). These sizes are reported as the expected ultimate height of these trees in the regions shown. The figures for the West Coast are from the editors of Sunset Magazine (1967); the Midwest are from Robinson (1960), the East Coast are from Wyman (1965) and the Intermountain areas are from Wilmore (1977). In almost every case, the expected ultimate size of a tree grown in the intermountain region is substantia11y smaller than if that same specific tree was grown in another part of the country. For this reason, literature that is written for other parts of the country is not adequate for use in the Intermountain region. Some books have been intended for use for the entire country. Again, it is easy to see that the variation from region to region ) limits the value of such work. Survey of Plant Materials Professionals Two surveys were conducted to determine which plant materials were available and adapted to the Intermountain region. The first of these two was made of a number of Intermountain plant materials experts. A list of broadleaf trees, coniferous trees, broadleaf shrubs, coniferous shrubs, vines, ground covers, ornamental grasses, and Table 3.2.

The list was composed of species and subspecies of plants that are taught in plant materials courses at Utah State University (Brooks and MOrse, 1976), Colorado State University (Macksam, 1974), or are reported by various authors (Brooks, 1973; Kelly, 1956, 1970, 1975, 1976; Sutton, 1974; and Johnson, 1970) to be used in the Intermountain region. On the iist of plant materials that were sent to these experts were: 1. 208 different species or subspecies of broadleaf trees; 2. 53 different species or subspecies of coniferous trees; 3. 239 different species or subspecies of broadleaf shrubs; 4. 71 different species or subspecies of coniferous shrubs; 5. 24 different species or subspecies of vines; 6. 22 different species or subspecies of groWld covers; 7: 10 different species or subspecies of ornamental grasses; 8. 7 different species of miscellaneous materials. Nineteen plant materials professionals were selected to participate in this survey. Each was chosen for his extensive experience with plant materials in the Intermountain area. These experts included professional landscape architects, horticulturists, foresters, and nurserymen. Fifteen of the nineteen people responded to the survey, a return rate of almost 80 percent. A list of the respondents and their professional affiliations are found in Appendix B of this thesis. Each survey participant was requested to review the list of plant materials and to place a checkmark (v') in front of each plant that in their experience met each of the fol~wing criteria: 38 1. the plant is tolerant of our climatic or microclimatic conditions; 2. the plant is available in our Intermountain region (either commercially imported or propagated or collected); 3. the plant's characteristics can provide aesthetic or utilitarian usefulness in the landscape. A copy of the cover letter that accompanied the survey list sent to each participant is included in Appendix B. The three selection criteria outlined above were developed from the findings of the literature review previously concluded (see Chapter II). Sutton (1974) conducted a survey to determine what criteria were helpful in evaluating the potential usefulness of plant materials. His nearly 60 informational categories may also be aggregated into three groups of information similar to the three selection criteria outlined above. The results of this survey are summarized in the plant matrix in Appendix A. Three columns show the collective evaluation of each plant by the respondents. The columns show the percentage of respondents that marked the plants as "fit" (meeting all three of the selection criteria). Some participants elected to comment about the potential of some plants to meet one or two but not all three of the criteria. These plants were recordea as conditionally fit. Because half of the participants are located in Colorado and the other half in Utah, a comparison is made between the responses of the two groups as well as an aggregate evaluation for the whole group. The survey of climatic conditions of the region (see the first portion of this chapter) showed that the environment is somewhat harsher in 39 the Front Range area than in the Wasatch Front area. scores 1 The fitness of the Colorado respondents are generally lower than the Utah respondents, reflecting their harsher environment. Survey of Intermountain Nurseries A survey was also made of several Intermountain nursery catalogs to determine which plants are commercially available. MOst local large wholesale nurseries in the Intermountain area import most of their stock from other parts of the country because of the harshness of the local climate. The smaller nurseries generally purchase their stock from these larger local wholesale nurseries or else from the same propagation nurseries. For this reason a survey of the smaller local nurseries is unnecessary. A review of the inventory of selected larger nurseries will give an accurate accounting or the commercial availability of plant materials for the region. The catalogs of five large intermountain nurseries were surveyed and recorded on a list of the plant materials. in this survey. Two other plant material listings were also included The first was the catalog of a large propagation nurserY ,of California that supplies a large portion of the plants imported into the region. The other was the index of plant materials sources of the AAN (American Association of Nurserymen, 1977). 1 The fitness score, which represents just the percentage of respondents who marked the plant, is found by assigning a value of one to the plant if it is marked fit and a value of one-half to the plant if it is marked conditionally fit. The aggregate percentage of fitness for each plant is then calculated as the sum of the score of that plant divided by the number of respondents. For example, if a plant was marked as fit by eleven respondents and as conditionally fit by two others, its percentage of fitness would be: [(11 X 1) + (2 X .5)] + 15 = 80 percent. ". 40 An availability percentage score I is assigned each plant in a manner similar to the fitness score of plant materials experts survey. The results of this survey are summarized as percent availability score recorded on the plant materials matrix in Appendix A. A list of the nursery catalogs reviewed in this survey are included in Appendix C of this thesis. I Each plant received a score of one for each local nursery that carried it and a score of one-half for each listing in either the catalog of the propagation nursery or the AAN catalog. If a plant material was listed in three local nurseries and one of the others, its availability score would be: [(3 X 1) + (1 X .5)] f 5 which is equal to 70 percent. A plant receives only one-half point for being listed in either the propagation nursery catalog or the AAN catalog because although it is commercially available somewhere in the country, it is not as easily accessible as material available locally. 41 CHAPTER IV RESULTS AND CONCLUSIONS All of the surveys conducted as part of this research have been directed at determining the validity of the basic assumptions outlined in Chapter I. The review of the historical associations of plants and people (see Chapter II) has shown that plant materials writers believe that good information about specific plants is important to successful design use of those plants. They have said that planting designers need to know how a plant will respond to climatic and environmental stimuli. They have also said that the designer must know the design factors of the plants, including its visual characteristics and its potential usefulness in the landscape. These findings confirm the first assumption of this thesis: that planting designers need to have descriptive information on the environmental and cultural adaptation, the potential landscape value and use, the availability, and the botanical morphology of the plant materials that they use. As the literature survey shows, other authors have concurred with this assumption and have sought to prepare reference texts to provide the necessary information. The second portion of the literature survey has reviewed these reference texts to evaluate their appropriateness for use in the Intermountain region. The matrix summary of plant materials reference texts (see Table 2.2, page 20) shows that many authors have made substantial contri~us to the literature as a whole. However, there 42 is no single reference text that provides all of the necessary information in a form useful to landscape architects and horticulturists working in the Intermountain region. Plant Materials Reference Proposed It has been shown that no plant materials reference text for the Intermountain presently exists. be prepared. It is proposed that such a reference This proposal has also been made by George W. Kelly who feels that "So long as the garden writers and horticultural experts of the east ignore us, we must furnish our own garden literature that fits our climatic conditions."l three sections: This reference book should be divided into (1) a description of the Intermountain region; (2) descriptions of individual plants; and (3) other related information to make the work more useful. Description of the Intermountain region The first section of this reference book should describe the Intermountain area. It should provide the basic information necessary for the /designer to understand the type of regional environment and landscape that he is working in. The review of the Intermountain climate (see Chapter III) "has shown the region to have a substantially different plant environment than other parts of the country. The reference work should show how plants generally respond to the low annual precipitation, high diurnal temperature change, low annual 1 Personal letter from George W. Kelly to Kenneth Brooks, February 8, 1977. " ". "" 43 average minimum temperature, low relative humidity, drying winds of high velocity, high light intensity, and shallow soils of low fertility, low organic matter and high pH. A description of environ- mental variation due to architectural and topographical microclimates should also be included. Descriptions of individual plant materials The surveys conducted as a part of this thesis have shown that the information needed by landscape architects and other planting designers can be organized into three categories. These include: (1) the environmental and cultural adaptation of each plant; (2) its landscape value and use; and (3) a botanical description. A proposed plant materials information recording format is shown in Figure 4.1. An example of a completed sheet for one species is shown in Figure 4.2. This format was developed by the author (Brooks and Morse, 1976a and 1976b) for use in teaching plant materials classes at Utah State University during 1974-1977, and found to be at least as informative and useful as any other format suggested by other authors. The information on the sheets would generalize the typical responses of the species to various environmental and cultural exposures. Genetic vari~lty and unique microclimatic exposures could be expected to cause plants to express characteristics not described on the sheet. Having descriptive information about a region, no matter how extensive, does not excuse the landscape architect from his responsibility of determining any unique environmental characteristics of a project site.

It is headed by the recognized genus and species of the plant to be described. A subspecies or varietal name is included here if the sheet is to be devoted to the subspecies. For most cases, however, the sheet would be for describing the typical environmental or heritable character of the species and each of the subspecies would have special notes at the end of the sheet. To be consistent with the rules of plant nomenclature (Bailey, 1963; Dirr, 1975), the botanical name would be either in an italicized typeface or underlined. The generic name would be capitalized and, consistent with contemporary practice, the specific name would be all lower-case letters. Also listed on the heading of the sheet would be the popular common name of the plant. The next descriptor would be TYPE which places the plant in a basic physiognomic group. The plant would be classified as deciduous, semi-evergreen, or evergreen. shrub, ground cover or vine. It would also be described as a tree, If the plant is not made up of woody tissue (as is a tree or shrub), it will also be described as semiwoody (suffruticose-a perennial with only the lower stems woody and persistant) or herbacious ( a non-woody perennial). Following TYPE would be FAMILY. This is just the taxanomic family that botanists have placed the genus in. be the last of the classification descriptors. OTHER NAMES would Any other common names or botanical synonyms would be listed and explained in this category. 48 The Environmental and Cultural Adaptation section describes the typical responses of the plant to environmental conditions. It will also suggest cultural and maintenance practices necessary for the successful use of the plant. The first category would be ZONE. This is based on the Plant Hardiness Zone system of the United States Department of Agriculture. Chapter III has already shown that the Zone system by itself has very limited usefulness in this part of the country and that the U.S.D.A. Map of Plant Hardiness Zones is quite inaccurate in this mountainous landscape. However, the numerical rating given by other authors is helpful in determining the relative annual average minimum temperature tolerance of the plant and is therefore included. The INTRODUCED category would give the year (as reported by Rehder,' 1940) that the plant was introduced to cultivation in North America. This could be importation from another continent or collection from natural occurrence on this continent for cultivation. For hybridized plants, this category would give the date of hybridization. The ORIGIN descriptor would list (after Rehder, 1940) the part of the world where the plant originated. If the plant is a horti- culturally hybridized species, this category would list its parentage. The ASSOCIATION category is for listing some of the other major genera of plants that are commonly found growing with the plant in question. In some cases it will be convenient to give the name of a specific plant association while in other cases more available 49 information will allow a listing of the dominate and understory vegetation found growing with this plant. The SOIL & MOISTURE category would describe the preferred soil and moisture environment for the plant. Consideration of soil texture, soil pH, rockiness, drought, drainage and irrigation tolerances would be important. The EXPOSURE descriptor would describe the preferred exposure of the plant to light and atmospheric factors. Tolerances to full sun, full shade, reflected heat, cold pockets, storm winds, dessication, and snow loads would be included here. The TRANSPLANTING & MAINTENANCE category would describe the typical and specialized cultural requirements of the plant. It would specify the tolerance of the plant to various methods (bare-root, balled and burlapped, container established, mechanical spade) of transplanting. If plant age is especially important to successful transplanting, it would also be included. The tolerance of the plant to pruning and shearing (severe pruning such as topiary and formal hedging) would be listed under this section. Any special irrigation or other maintenance needs of the plant would be described in this section along with susceptibility to insect or disease problems. The Landscape Value and Use section of this sheet would provide information that has been traditionally considered by designers as the "design" factors of the plant, that is, its inherited physiognomic characteristics. The first part of this section would describe physical attributes' of the plant and the last portion of the section would recommend potential uses of the plant. 50 The first category would be FORM. It would describe the overall physical appearance of the plant, first giving its relative size (large, medium, small). Size is compared to other plants of the same type--a small tree is not as large as a be larger than a large shrub. medi~sz one, but it will The plant would also be described as deciduous, semi-evergreen, or evergreen; and a classification as a tree, shrub, ground cover or vine would be included. This is a duplication of the information listed under TYPE but it is included here under FORM as well because it is part of the description of the form of a plant. Also to be included in this category would be any other description of the shape of the plant, or its branching habit necessary to describe its appearance. The TEXTURE descriptor would describe the plant as either coarse, medium "or fine textured (as compared to other plants of similar TYPE). If there is a significant seasonal variation in the textural appearance of the plant, these would be specified in this section. The size of the plant would be described in a couple of categories. materi~ All sizes would be average ranges for healthy plant growing under average environmental conditions found in the Intermountain area. All measurements would be expressed in .. English units (feet and inches) followed parenthetically by metric conversions. The ULTIMATE SIZE would list a range for both height and spread of the plant. For trees, a TWENTY YEAR SIZE would list the average ranges of height and spread to be expected of the tree at that age. For shrubs, ground covers and vines, a FIVE YEAR SIZE would list average ranges of height and spread to be expected of the plant material at that age. 51 A RATE OF GROWTH category would describe a plant growth rate as either slow, moderate or rapid. This would be the typical growth rate potential of this plant under average environmental conditions compared to plants of the same TYPE. Similarly, the LIFE SPAN descriptor would describe the potential life span of the plant as either short, moderate or long. Again, the relative comparison would be made for a typical specimen growing under average cultural and environmental conditions compared to other plants of similar TYPE. The SPACING FOR MASSING category would suggest a spacing distance for the plant. The distance would be the "on center" measurement that would be recommended so that the planting provides a massing design effect within the design' time period. This period is the time necessary for the design effect to mature, if plant stock of typical nursery size is installed. This period would be five years for shrubs, ground covers and vines, and twenty years for trees. The commercial AVAILABILITY is the next descriptor. The plant would be described as commonly found at few, some, many or most (Intermountain) nurseries. If the plant is commonly collected from local n9ncommercial sources, such a comment would be included. RELATIVE COST would also be given here. The The cost, described as high, moderate, or low, would be a comparison between this plant and other plants of similar TYPE, size, age, and condition. The last category of this section would be the VALUE, USE & RESTRICTIONS of the plant. This would include comments about the attractive or distractive characteristics of the plant. Traditional or common architectural, engineering, climate control, aesthetic and 52 other uses would be suggested here. features would be reviewed. Any distinctive or showy Special uses such as edible food, wildlife habitat or wildlife food would be noted. Common problems of the plant such as disease or insect susceptibility or special maintenance requirements would also be included. Any threats such as poisonous fruit or foliage, or special landscape problems such as invasive root systems, weak and falling branches or undesirable odors would be described in this category. Any other comments about the usefulness of the plant would also be included. The botanical description section is intended to provide a clear and complete morphological characterization of the plant. In order to express these exact morphological or taxanomical characteristics, basic botanical nomenclature would be used. This would make it necessary for the user of this section to be familiar with standard nomenclature or to use either a glossary in the book or another handbook such as those by Harrington (1957) or Porter (1967). FOLIAGE would be the first category. The first comment would be about any showy summer or fall foliar characteristics. begin the actual description of the leaves. listed as either evergreen or deciduous. Next would The foliage would be Next would be a basic phyllotaxus (leaf arrangement on the stem) designation of either opposite, alternate or whorled. Following would be a designation as either simple or compound foliage. If the leaves are compound, they would be further described as palmate, pinnate, bipinnate or trifoliate and .the number of leaflets commonly found would be given. The description of a single leaf would include the shape, size, and texture of the · leaf blade, margin, tip, base, and surface. The 53 size, form and texture of petiole and stipular structures would be described. The last portion of the FOLIAGE category would be a description of the color of the foliage in each season. The INFLORESCENCE category would describe the flowers and related structures. The first item would be a description of landscape effect of the flowers. If the floral display is very prominent, the INFLORESCENCE would be described as showy. If the floral display can be seen in the landscape but it is not so prominent that the plant is selected especially for flowers, the INFLORESCENCE would be described as conspicuous. If the flowers provide no flowering effect in the landscape, they would be considered to be inconspicuous. The next information provided would be the season of flowering, flower color, presence of fragrance, and size. Perfect, monoecious, or dioecious flowering condition would be next, followed by a description of the inflorescence morphological type. The FRUIT descriptor would describe the morphological character and the landscape value of the fruit. The first description would evaluate the fruit as showy, conspicuous, or inconspicuous. Following would be the details of season of fruiting effect, color, size, and type. Comments about edibility or poisonousness or attractiveness .. to wildlife would be included. If the fruit has any unattractive attributes, these would also be included. The BARK & TWIGS category would describe the color, texture, and other physical characteristics of bark, branches, twigs or stems. If there are special or unique attributes 'of internal portions of the stems that could aid in identification of the plant, these would be described. 54 The presence of prominent morphological structures such as thorns, lenticels, tendrils, pubescence or bloom would be discussed. The BUDS descriptor would discuss the size, form, texture, and color attributes of vegetative buds. This category would be useful primarily for characterization of winter buds of deciduous plant material. The final botanical descriptor would be a description of the ROOTS. A characteriziation of root habit, either taproot or fibrous root system would be followed by any comments of suckering, rhizome or stolon tendencies. If the plant has important subspecies, they would be discussed in a section following the botanical description. For each subspecies, the botanical and common name would be given and a discussion of its unique ' environmental and cultural adaptation, landscape value and use, or botanical form would be presented. The plant materials sheets would be even more useful if they also presented sketches of the plant. Good sketches would be preferable to photographs because of their ability to portray typical characteristics without problems of photographic background or lack of good specimens. The cost of reproduction would also be considerably less for sketches. Ideally, each plant would have a sketch of its silhouette form, its foliage, flowers, fruits, and twig with bud. The plants selected for inclusion are proposed in Tables 4.1 and 4.2 (see pages 60, 66). These proposed lists were developed from the results of the surveys of Intermountain plant materials experts and nursery inventories (see Chapter III and Appendix A). Table 4.1, Primary list of plant materials recommended for the Intermountain 55 region, is made up of those plants from Appendix A that received at least a 75 percentage rating from the Intermountain authors survey, the experts surveyor the nursery survey. These are the plants with the best potential for being adapted to . the environment, useful in designed landscapes, and commercially available. Table 4.2, Secondary list of plant materials recommended for the Intermountain region is made up of those plants that received a 50 to 74 percent rating in the Intermountain authors survey, the experts survey, or the nursery survey. The plants on the secondary list have restricted usefulness because of limited environmental hardiness, less landscape design value, or low commercial availability. The work of these Inter- mountain authors (Colorado State University Extension Service, undated; Feucht and Macksam, 1968; Huddleston and Hussey, 1975; Johnson, 1970; Ke11y,'1957, 1970, 1975, and 1976; Reimschusse1, 1964; Shaw, 1963; and Sutton, 1974) is reviewed in Table 2.2 (see page 20) while the plants that they list are shown in Appendix A. Other related information and references The third section of the plant materials reference book would be made up of special helps. These would include an illustrated glossary < . of the environmental, design, and botanical terms used in the book. A list of other helpful references or literature should be provided. A glossary that shows pronunciation and origin or translated meaning of botanical names should be given. An index of botanical and common names found · in the book would help "quick reference" use of it. Including a number of quick reference lists of plants for special 56 needs or uses would increase the usefulness of the book. Such lists might include: 1. plants (by type) adapted to specific environmental condi- tions, such as tolerance to alkaline or heavy soils, non-irrigated or wet conditions, windy exposures, sunny or shaded locations, reflected heat, or restricted root zone; 2. plants (by type) of given aesthetic characteristics as form, relative size, flowering effect (color, fragrance or season), fruiting effect (color, fragrance, or season), special foliage color, texture; 3. plants (by typ~ of given growth character such as life span or growth rate; 4. plants (by type) with potential for special uses such as street "tree plantings, screening masses, shade, bird or wildlife food or habitat, edible fruit, traffic control, erosion control, wind break, or special effects (espalier, pollardy, pleaching, topiary or bonsai). Recommendations for Further Study Throughout the course of this research, a number of Intermountain plant materials issues have surfaced that have been deliberately excluded from the discussion. It is not that these issues are not important but rather that they have no direct bearing on the hypothesis that there is inadequate information on landscape plant materials in the Intermountain region. 57 One of the major problems encountered within this research was inconsistency with plant names. On one hand, some plants are known by several common names, while on the other, a single common name may be used for more than one specific plant. This is the very reason for using scientific names, however, not all of the regional nurseries follow this rule. Although the inventories of most of the more respected nurseries are cataloged by scientific name, there are a number of catalogs full of vague common names. lead to further problems. Name confusion may For example, a RIVER BIRCH purchased within the region may be either a Betula occidentalis, a Betula fontials~ or a Betula papyrifera, depending upon which nursery it was purchased from. Each of these trees will respond differently in the landscape and therefore this discrepancy can cause a planting design to be less succesiful. There is also a problem of multiple scientific names for single plants, such as the CRIMSON KING NORWAY MAPLE which is known both as Acer platanoides 'Crimson King' and Acer platanoides schwedleri nigra. A similar problem occurs when botanists update a scientific name but the old one or an inaccurate one maintains itself within the horticultural trade. A very prominent example of this is the genera Mahonia, which is now considered Berberis by most botanists l but is still sold in the nurseries as Mahonia. Such problems with names should be resolved within the proposed reference book, however, it would probably be more convenient to lpersonal conversations with MI. Richard Walters, Herbarium Curator, Department of Botany and Plant Pathology, Colorado State University, Ft. Collins, Colorado, during April and May, 1973. 58 prepare a list of correct names with their historical or popular synonyms before the handbook is begun. Another issue to review before the preparation of the handbook is the manner in which information will be gathered for presentation. Should all of the information come from observations of statistically sound plot design? Should it come from the empirical observations of a single expert or group of experts? Should it be developed from the consensus of opinion surveys of a large. number of experts? Because the information demand suggested for each plant sheet in the proposed handbook is so large and variable, the research should attempt to take advantage of as much professional experience as possible while maintaining a high degree of scientific objectivity. The actual methods, intensity, and form of research would be highly dependent upon the types of time, facilities, staff and funding resources available. There are several other issues to be considered as related to this thesis that deserve further exploration and full development outside the scope of this thesis. 1. These issues may include: the effects of using exotic plant materials on the natural Intermountain landscape or its gene pool; 2. the high irrigation requirements of exotic plant materials; 3. the landscape value of indigenous and endemic plant materials; 4. the propagation and marketing of indigenous or endemic plant materials not presently commercially available; 5. the environmental adaptability of exotic plant materials produced in other parts of the country and imported for use in the Intermountain region; - 59 6. the availability of plant materials by size, relative cost, and conditions (such as bare root, B&B, or container); 7. descriptions of Intermountain plant material insect and disease threats and management. The exploration of each of these issues would contribute greatly to the general usefulness of Intermountain plant materials reference literature. Summary This thesis has evaluated Intermountain plant materials literature and shown that it is inadequate for use by professional planting designers. The review of contemporary reference literature has shown the types of information that is needed. Evaluations of surveys of local professionals and nurseries have shown which plant materials are environmentally adapted, commercially available, and useful in landscape design work. A detailed proposal for preparation of a plant materials reference handbook is made as a result of the research. 60 Table 4.1. Primary list of plant materials for the Intermountain region.

The next two columns on the matrix report the plants that are taught in plant materials courses at Colorado State University (Macks am , undated) and Utah State University (Brooks and Morse, 1976a, 1976b). An "X" in the column means that the plant is included in the class. These are the universities with the largest landscape architectural and horticultural programs within the study region. The next eleven columns report the plant materials that intermountain region plant materials authors selected from Table 2.2 have include4 in their work. is included. only. An "X" in the column means that the plant Several of the works contain trees only or ground covers For these works the nonapplicable plants have an "N" marked in the column. For example, Johnson's (1970) book contains only trees and so Ajuga reptens, a ground cover, would be marked "N." The eleven authors listed on the matrix are referenced in the Literature Cited section of the thesis and are listed below: 1. undated) Extension (Colorado State University Extension Service, 82 2. Feucht (and Macksam, 1968) 3. Huddleston (and Hussey, 1975) 4. Johnson (1970) 5. Kelly (1957) 6. Kelly (1970) 7. Kelly (1975) 8. Kelly (1976) 9. Reimschussel (1964) 10. Shaw (1963) 11. Sutton (1974) In the following column is placed the percentage of inclusion by the authors. (The number of "X"s divided by the number of authors. If there are any "N"s for a particular plant, the number of authors considered is reduced accordingly. ) The next three columns summarize the survey of plant materials experts (see Chapter III and Appendix B) • The percentage of response for Colorado experts and Utah experts and the aggregation of all is shown. Some of the plants were added after the experts survey was completed and are therefore marked with an "N." The next column shows the percentage of nurseries that carry the plant (see Chapter III and Appendix C). The last column makes a recommendation on the suitability of the plant for use in the Intermountain regiop based on criteria established in Chapter IV.

These nineteen experts were selected for their experience with intermountain plants. Nine people from Colorado and ten from Utah were contacted by mail and asked to participate in the survey. cover letter follows on the next page.) (A copy of a typical Seven of the Coloradoans and eight of the Utahns responded for about an 80 percent response rate. , A list of the participants are given following the cover letter. A summary of the resul,ts of this survey are recorded in Appendix A of this thesis. 192 UTAH STATE COL LEG E 0 F UNIVERSITY · LOGAN . UTAH 84322 HUM A NIT I E S, ART SAN D SOC I A L SCI E: NeE DEPARTMENT OF LANDSCAPE ARCHITECTURE AND ENVIRONMENTAL PLANNING, UMC 12 February 1, 1977 Mr. Arden Larsen Campus Planning Department Annex 105 Room 2202 University of Utah 84112 Dear Mr. Larsen: I am a graduate student in landscape architecture here at Utah State University. I am now writing a thesis on landscape plant materials and I would like to ask you for some help if you have a little bit of time and are interested. The purpose of the work is to describe the cultural and environmental adaptation, the characteristic attributes and the landscape value and use of selected plant materjals. The work is intended to be used as a reference source for l andscape architects, horticulturists. arborists, nurserymen, county extension agents, and students. I wculd be very grateful for your assistance if you can help me. I have comp ile d a base list of plant materials that have been reported as being used horticulturally in inter-mountain landscapes. I am surveying a number of plant materials experts, such as yourself, to determine which plants on thi~ list are the most useful in our region. There are three criteria for evaluating the materials: 1) the plant is tolerant of our climatic or microclimatic conditions 2) the plant is available in our inter-mountain region (either commercially imported or propogated or collected) 3) the plant's characteristics can provide aesthetic or utilitarian usefulness in the landscape Please place a checkmark (vt in front of each plant that you have found in your experience to meet each of the above three criteria. If there are other plants that you believe should be added, please list them atter each section. Any comments that you care to make are welcome. After checking the list, please return it to me in the enclosed envelope. You may make yourself a copy of the list if you desire. I will also send you a report of the results of the survey if you request it when you return the checked list. T would also like to know if you would be interested in reviewing and commenting on portion of the manuscript as they are prepared. Thankyou for your time and your help. ~g Kenneth R.

The nurseries selected are all fairly large operations with both retail and wholesale services. Most smaller intermountain nurse~i usually purchase their stock from these bigger nurseries or else import the same materials from other areas. One propagation nursery from southern California was also reviewed since most local nurseries that do import shrubs from outside the region buy from this California nursery. The index of Sources of Plants and Related Supplies (American Association of Nurserymen, 1976-1977) was also reviewed to see which plants were listed as commercially available by the American Association of Nurserymen. The results of this survey are included in Appendix A. The nurseries included in the survey are listed below: Forest Hills Nursery SpIt Lake City, Utah Western Evergreen Nursery Golden, Colorado Porter-Walton Nursery Centerville, Utah Wilmore Nurseries Wheat Ridge, Colorado Valley Nursery Uintah, Utah Monrovia Nurseries Monrovia, California
