Posts Tagged ‘Spirea’

There wasn’t room in my last post on aquatics to include them all, but there are many other pond side plants blooming at this time of year. One of the prettiest is meadow sweet (Spirea alba.) This plant likes moist ground and I have found it near water more often than not but I’ve seen it in drier spots as well.

Meadowsweet flowers have long stamens that always make them look kind of fuzzy. Some people confuse this plant, which is a shrub, with steeplebush (Spiraea tomentosa), which is also a shrub, but steeplebush has pink flowers and the undersides of its leaves are silvery-white, while the undersides of meadowsweet leaves are green.

Meadowsweet is in the spirea family so I thought I’d show you this pink spirea I found in a local garden so you could see the resemblance. It also looks fuzzy because of the many stamens.  

Our native common elderberry bushes (Sambucus nigra canadensis) are blooming and can be seen dotted around the landscape, especially near brooks and streams, or swamps as this one was. Its mounded shape and flattish, off white flower heads make it very easy to identify, even from a distance.

Common elderberry flower clusters look similar to Queen Anne’s lace. Each flower is tiny at only 1/4 inch across, and has 5 white petals or lobes, 5 yellow tipped stamens and 3 very small styles that fall off early after blooming. Each flower will be replaced by a single black (dark purple) drupe. A drupe is a fleshy fruit with a single seed like a peach or cherry. Native Americans dried the fruit for winter use and soaked the berry stems in water to make a black dye for basketry.

Blue, bell shaped flowers all on one side of the stem can mean only one thing; creeping bellflower (Campanula rapunculoides.) The pretty flowered plant was introduced as an ornamental from Europe and has escaped gardens to usually live in dry, shaded places but it will also grow in full sun. It is a late bloomer but is usually finished by the time the goldenrods have their biggest flush of bloom. It is considered an invasive plant in some places because it is hard to get rid of once it has become established. It can choke out weaker native plants if it is left alone. It isn’t considered invasive here in New Hampshire though, and in fact I usually have to look for quite a while to find it. When I do it is usually growing on forest edges.

Purple flowering raspberry (Rubus odoratus) is in the rose family and it isn’t hard to tell by the flowers, but the big light gathering leaves look more like a maple than a rose. The big leaves give it a certain tolerance for low light, and that’s how it can grow in the shade so well. The fruit looks like a giant raspberry, about the size of the tip of your thumb. I’ve heard that it is close to tasteless but some say if you put a berry on the very tip of your tongue it will be delicious. I keep forgetting to try it.

A couple of years ago I found a small colony of long leaf speedwell (Veronica longifolia.) I’m happy to say there are more blossoms this year. I’ve never seen it growing in the wild until I found it here. It’s a pretty plant that is native to Europe and China and grows on steppes, grassy mountain slopes, meadows at forest edges and birch forests. Here in the U.S. it is commonly found in gardens but it has obviously escaped. It certainly doesn’t seem to be aggressive or invasive. I love its showy blue flower spikes.

Each tiny long leaf speedwell blossom is purple–blue or occasionally white, about a quarter inch across and 4 lobed with quite a long tube. Each has 2 stamens and a single pistil. Another very similar plant is Culver’s root (Veronicastrum virginicum) but culver’s root doesn’t grow naturally in New Hampshire.

Canada thistle (Cirsium arvense) blooms in the tall grass of unmown meadows, usually in large colonies. This plant isn’t covered with sharp spines like the larger bull thistle but it does have small spines along the leaf margins and stem. Despite its common name the plant is actually a native of Europe but has spread to virtually every country in the northern hemisphere. It has a deep and extensive creeping root system and is nearly impossible to eradicate once it gains a foothold. For that reason it is considered a noxious weed in many states.

I found this Deptford pink (Dianthus armeria) in the tall grass from under a tree and was surprised to see it at two feet tall. They don’t always grow in the same large clumps as their cousins the maiden pinks (Dianthus deltoids) do, but I saw a few this day. They also don’t have the same bold, jagged, deep maroon ring near their center as maiden pinks do, and that’s a good means of identification. Both plants are originally from Europe and have escaped cultivation. Maiden pinks seem to prefer open lawns and meadows while Deptford pinks hide their beautiful little faces in the sunny edges of the forest.

An irrigation system was put in a local park last year and a bed where Asiatic dayflower (Commelina communis) grew was completely dug up. Since that is the only place I’ve ever seen it I doubted I would see it again, but this year there must have been a dozen plants where before there were two. That tells me it must grow from root cuttings, much like phlox does. I was happy to see so many because it is rare here. When I saw photos of the flower I thought it would be as big as a tradescantia blossom but it is only half that size. It is an introduced plant from China and Japan but it could hardly be called invasive because I’ve seen maybe 10 blossoms in 60+ years. I’d like to see more of them; I love that shade of blue.

Arrowleaf tearthumb (Polygonum sagittatum) is in the smartweed family, which gets its common name from the way your tongue will smart if you eat its peppery parts. Though the flower buds in this family of plants seem like they never open they do, sort of. They look like they only open about halfway though and I find the buds as pretty as the blossoms. This plant is a kind of rambler / sprawler that winds its way over nearby plants so it can get as much sunshine as possible. It often grows in deep shade but it will also grow in full sun, so it has covered all the bases.

Tearthumb got that name because it will indeed tear your thumb or any other body part that comes into contact with it. Many a gardener has regretted trying to pull it up without gloves on, because when the small but sharp barbs (prickles, botanically) along its stems slip through your hand they act like a saw and make you sorry that you ever touched it. They point down toward the soil so when you pull up on it you get a nasty surprise. The plant uses these prickles for support when it climbs over other plants, and they work well. Sometimes the stems and prickles are red but in this example they were green. Tearthumb is considered a wetland indicator because it likes to grow in very moist to wet soil. I almost always find it near water, often blooming quite late into summer.

Last year I found a place where quite a lot of Carolina horse nettle (Solanum carolinense) grew and I was surprised because it’s a plant that I’ve never seen anywhere before.  From what I’ve read it is not a true nettle, but instead is a member of the nightshade family. The flowers have five petals and are usually white or purple with yellow centers. There is a blue variant that resembles the tomato flower, which makes sense since tomatoes are also in the nightshade family. The flowers have no scent but the foliage has a certain odor that I find disagreeable.

Horse nettle’s stem and undersides of larger leaf veins are covered with spines and I can attest to their sharpness. It’s hard to grab it anywhere and I’ve been pricked by it several times just trying to turn a leaf over. This plant is native to our southern states, so why it is growing here is a mystery. It seems to like where it grows; there must be 30-40 plants growing there. I can see its spreading becoming a real problem.

You wouldn’t think that you’d get pricked by something that looks as soft and furry as motherwort (Leonurus cardiaca) but the seedpods are actually quite sharp and prickly. The small furry white to light purple flowers are easy to miss. At a glance this plant might resemble one of the nettle family but the square stems show it to be in the mint family. The tiny flowers grow in a whorl around the stem in the leaf axils. This plant, originally from Asia, is considered an invasive weed but I don’t see it that often and I don’t think I’ve ever seen more than 2 or 3 plants growing together.  It was brought to this country because of its long history of medicinal use in Europe and Asia. The ancient Greeks and Romans used motherwort medicinally and it is still used today to decrease nervous irritability and quiet the nervous system. There is supposed to be no better herb for strengthening and gladdening the heart, and it is sold in powdered and liquid form. I find it along roads and in fields.

Maleberry shrubs (Lyonia ligustrina) line the shores of the ponds and rivers along with blueberries, and sometimes it can be hard to tell the two apart. The flowers of maleberrry, though nearly the same shape and color, are about half the size of a blueberry flower and the shrub blooms about a month later. There are often berries on the blueberries before maleberrry blossoms.

Maleberry blossoms become small, hard brown 5 part seed capsules that persist on the plant, often for over a year. They make maleberrry very easy to identify, especially in spring; just look for the seed capsules and you’ll know it isn’t a blueberry. This is one of a very few plants which I can’t find a Native American use for, but I’d bet they had one.

Spreading dogbane’s (Apocynum androsaemifolium) bell shaped flowers are very fragrant and I love to smell then when I can find one without an insect in it. They’re also very pretty, with faint pink stripes on the inside. They remind me of lily of the valley flowers but are quite a lot larger.

Spreading dogbane is toxic to both dogs and humans, but insects love it. It’s closely related to milkweeds and has milky sap like they do. Monarch butterflies drink the nectar but I rarely see one on them. Though it is an herbaceous perennial its growth habit makes it look like a 3 foot tall shrub. The Apocynum part of its scientific name means “away from dog.” Not only dogs but most other animals avoid it because of its toxic sap.

I really do hate to say it but goldenrod is blooming already. Is it happening earlier each year or is it my imagination? In any event for me no other flowers except maybe asters whisper so loudly of the coming fall. Actually I love fall, it’s what comes after that I’m not looking forward to. When I was a boy summer seemed to stretch on almost without end but now it seems to pass almost in the wink of an eye.

Summer has always been good to me, even the bittersweet end, with the slanted yellow light.

Flowers, both wild and cultivated, are everywhere you look right now. Since I’ve never met a flower that I didn’t like, I like to occasionally show a few garden flowers on this blog along with the wildflowers and other bits of nature. After all, all flowers were once wild. I found this strange dwarf sunflower (Helianthus) plant in a local park. The thing that made it so strange, I thought, were the large flowers on such a small plant. They had to have been the size of a small dinner plate and looked odd on a plant only 18 inches tall. But that’s just my opinion and in any case, they were very beautiful flowers. A longtime garden favorite of mine is the painted daisy (Chrysanthemum coccineum.) This plant is in the Chrysanthemum family and is also called pyrethrum.  Gardeners may recognize the word pyrethrum from the natural insect sprays that are made from this plant. Pyrethrum has been used as an insecticide for centuries and is still used today by people not wanting to use chemical pesticides. One of these grew in my garden for many years but I think the recent unusually warm winter was too much for it since it never came up this spring.  The plant pictured grows at a local school. The hood shaped upper petal of a monkshood (Aconitum) flower helps to easily identify it. I found this one growing in a local children’s park, which is disturbing since Aconite, which monkshood is, is one of the most poisonous plants known.  In fact, some species of aconite are so poisonous that their aconitine toxin can easily be absorbed through the skin while picking their leaves. Aconite is also called wolf’s bane, leopard’s bane, and Friar’s cap. People who have mistaken its roots for horseradish have died 4-6 hours after eating them. This plant has been known medicinally for centuries and has long been used to poison arrows and spears.  Children should always be warned about its dangers. Spirea (Spiraea ) is a very common shrub often seen planted in store and bank parking lots because it needs very little care. The old fashioned white varieties were called bridal wreath but now many hybrids exist and usually have white to pink flowers. However, some I’ve seen look almost neon blue, so plant breeders are still working on it. The plant pictured was a very low growing dwarf that was absolutely covered with mounds of pink flowers. I found it growing in a store parking lot. This plant fools a lot of people because the leaves look a lot like sumac leaves. Then the flower buds appear and it’s clear that it isn’t sumac, but what is it?  Its name is false spirea (Sorbaria sorbifolia.) If you look at the spirea plant in the previous photo you’ll see small round, pink flower buds. The false spirea has small, round, white flower buds and when they open like in the photo below the flowers look almost like those of spirea. The beautiful plumes of false spirea (Sorbaria sorbifolia) flowers cover this small shrub that looks much like stag horn sumac. Its round white buds and long stamens on the flowers point to it being something very different than sumac though. Common foxglove (Digitalis purpurea ) blooms in my yard wherever it happens to grow because it self-sows so easily. Since I no longer have small children I don’t have to worry, but this is another plant that children should be warned away from. The heart medicine digitalis was originally made from plants in this family. All parts of the plant are poisonous and people who have mistaken the leaves for those of comfrey have died. One half of a gram of dried seed is deadly. Other names for foxglove are witches’ gloves, dead men’s bells, thimbles, fairy cap, fairy glove, fairy thimbles, fairy finger, fairy bells, dog’s-finger, finger flower, lady’s-glove, lady’s-finger, lady ‘s-thimble, popdock, flapdock, flopdock, lion’s-mouth, rabbit’s-flower, cottagers, throatwort, Scotch mercury, bloody fingers, and virgin’s glove. The plant is originally from Europe and has been used medicinally for centuries. In old England picking foxgloves was unlucky, and its blooms were absolutely forbidden inside because it was believed that they gave witches and / or Beelzebub access to the house. This blossom is probably seen coast to coast, because it is the very popular Stella d’ Oro daylily (Hemerocallis.) The reason this plant is so popular is because it was one of the first “ever blooming” day lilies. The dwarf plant has flowers that only last a day like any daylily but there are so many of them that it blooms for months and will often be the latest blooming daylily in a flower bed. This plant was developed in 1975 and is still seen all along city streets and in commercial parking lots. This one grows at a local bank. Also growing at the same bank as the Stella d’ Oro daylily were large beds of ornamental flowering onion (Allium.) Alliums are useful bulbs that are a bridge between spring and summer flowering bulbs. The globular heads of star shaped flowers come in pink, white, blue, purple, and rarely yellow. These plants aren’t common but they should be used more than they are because they will bloom for a month or more. The flat topped flowers and feathery leaves of the common white roadside yarrow (achillea) are repeated in garden yarrow. The major difference is color and size of bloom; garden yarrow can be pink, yellow, white, red, and even apricot and the flowers are generally much larger than common yarrow. Yarrow is a native plant that is useful in sunny, dry spots in the garden. Its flower heads retain their color well when dried.Astilbe (Astilbe ) (pronounced ah-still-bee) is a perennial that doesn’t need fussing over. I planted several in my yard years ago and have hardly touched them since. I like the unusual feathery flower heads. I grow white, pink and red varieties, which is the extent of their color range. They are excellent for semi shade areas and look good planted alongside ferns and hostas. These flowers also dry well and will hold their color for months.Since Indigo is the color of a blue dye it seems strange to name a plant Yellow false indigo, but here it is. False indigo (Baptisa) is a shrub-like perennial with blue, purple, and even yellow flowers that resemble pea blossoms.  This is a very tough, 3-4 foot tall plant that can stand a lot of dryness. As the photo shows, bumble bees love it.  I found this example in a local park. This Shasta daisy (Chrysanthemum maximum) that I grow had tiny little flies all over it the day that I took this picture. I don’t know what they were and I’ve never noticed them on the plant before. The Shasta daisy was developed by plant breeder Luther Burbank over 100 years ago and was named for the white snow of Mount Shasta. These plants are a hybrid cross of the common roadside ox-eye daisy and an English field daisy called Leucanthemum maximum. They are one of the easiest perennials to grow and, other than weeding, need virtually no care. Dwarf varieties are less apt to have their stems bent over by heavy rains.
