Tips on Taking Care of your Cyclamen Houseplant

If you received or purchased a blooming  cyclamen over the holidays, here are tips for taking care of this regal queen.  Also called florist’s cyclamen (Cyclamen persicum), this houseplant blooms during the winter with flowers raised high above the foliage, lasting for several months. Cyclamen is available in a range of sizes, from mini to large, as well as magenta, red, pink, and white flower colors. Beautiful as it is, cyclamen is not an easy plant to grow.

While it is blooming, give it bright indirect light. It prefers day temperatures of 60-70 degrees and night temperatures of 40-50 degrees. It also prefers high humidity. Usually homes in the winter have low humidity so place the plant on a tray of pebbles with a little water. However, make sure you have a saucer between the container and the pebbles. The root system is a tuber that is prone to rot.

Water when the soil feels dry, like dry in the top inch, but before it is completely dry. Do not let it sit in water and do not let it sit in the saucer of water. Likewise, when watering, aim for the side of the crown, not on the leaves, and not on the crown (central growing point). If you purchased it in the decorative foil covering, it best to remove that and put the pot (make sure it has drainage holes) on a saucer.

Feed the plant with a diluted liquid low nitrogen fertilizer to prolong the blooms, such as an African violet fertilizer.

After flowering, the leaves will turn yellow. Your first thought may be that it is dying and you need to water or fertilize but don’t do that. The plant is beginning its dormant stage. Don’t try to keep it green with more watering, let it rest during the summer. Put the plant in a cool, dark area with good air circulation. Don’t water or feed during its dormant period.

In the late summer, early fall, bring the plant back to bright indirect light and water thoroughly at first. You will see new green growth. Treat it like when you first purchased it and it should bloom again. It may not look as luscious, but the regal queen should continue to hold her court as a long lasting houseplant.

Frosty Fern: A Unique Holiday Gift Plant

Frosty Fern available for sale now in garden centers

Poinsettias are traditional and cyclamens are beautiful, but a truly unique holiday gift plant is Frosty Fern. “Frosty” because of the white tips on the green foliage but “Fern” is just a marketing gimmick. Frosty Fern is not a fern but a type of spike moss (Selaginella), cousin to the resurrection fern (S. lepidophylla).

close up of the aerial roots

Only about 6 to 8 inches tall, Frosty Fern has fern-like, scalloped foliage with many aerial roots – the thin strands hanging down from the stems. The more humid the air, the more aerial roots develop. Keep in mind that the plants at the garden centers have green foliage and white tips with plenty of aerial roots because they have been grown in humid greenhouses. Now they look great as gift plants, filling that need to give someone a holiday gift who already has everything.

Although Frosty Fern does not mind your low light levels in your home, it does object to your dry home. This houseplant requires high humidity, as high as 70 percent. Likely this will prove a challenge, so it is best to think of Frosty Fern as a terrarium plant. Unless Frosty can take a shower with you in a bathroom with a bright window, it may be best to insert Frosty in a large terrarium or glass bowl.

In the summer, as the temperature increases, its frosty tips will revert to green but should become white again in the fall when temperatures drop. As a slow grower, Frosty Fern does not require a lot of food. Fertilizer once in the summer at a very diluted strength.

The soil should be moist but don’t let the plant sit in standing water. If the plant came in a decorative foil wrapper, remove it and make sure the container has drainage holes.

Frosty Ferns can be found at independent garden centers now but don’t expect to find them after the holidays. These special plants only make an appearance during the holidays so purchase one now!

Sneak Peak at New, Unique Houseplants from Costa Farms

Philodendron ‘Golden Crocodile’

In the beginning of March, I spent a few days in Miami attending Costa Farms’ Season Premiere event. This was at their trial gardens and for me as a garden communicator, this was an opportunity to see how plants performed as well as learn about new plant introductions and meet the plant breeders. Costa Farms is one of the largest horticultural growers in the world. It is a fourth generation, family-run company that employees more than 6,000 people and grows plants on 5,000 acres. The company started in 1961 when Jose Costa Senior purchased 30 acres to grow tomatoes in the winter and calamondin citrus in the summer. Soon he was growing houseplants and now the company has expanded into annuals, perennials, and tropical plants for the garden.

Philodendron ‘Ring of Fire’

I attended the event with several other GardenComm members. Justin Hancock, senior horticulturist at Costa Farms, treated us to a sneak preview of the 2023 and 2024 introductions for Costa Farms’ Trending Tropicals® collection. He also gave us a tour of the packing and shipping facility where orders are carefully wrapped, packaged, and put on trucks to deliver across the country. Each plant order comes with a postcard providing light, water, and fertilizer requirements as well as growing tips. They have a staff dedicated to answering the customers’ plant questions and a very informative website.

Although you can see their houseplants at Lowes, Home Depot, Walmart, and other retail locations, you can also buy direct via their shop costa website.

Most of the Trending Tropicals® collection of houseplants are selected by their plant hunters (yes, that really is a profession) who travel to other countries to look for unique plants that can be grown here. Once they identify possibilities, they bring them back to Costa Farms to propagate and trial before they are sold to the public. Some of the plants Justin showed us were discovered by staff at Costa Farms as “sports” (natural mutations) from their current inventory.

Dieffenbachia ‘Crocodile’

Justin showed us 19 new plants for 2023 and 2024 in one of the production warehouses. In my descriptions below, I hyperlinked to those varieties that are in stock and ready to be ordered directly from their website at the time of this writing.

Of the 19, there are three 2024 introductions that are not available yet and not on the Costa Farms’ website but here is a sneak peek at these fascinating plants. All are large houseplants, perfect for living room décor, and easy to grow in bright light. Philodendron ‘Golden Crocodile’ has large, serrated leaves that first appear as golden yellow maturing to light green. Philodendron ‘Ring of Fire’ has variegated foliage with splashes of white, cream, and yellow. Dieffenbachia ‘Crocodile’ has large green leaves speckled white or light green. The back of the leaves’ midrib has “scales” – like a crocodile’s back.

In the photo above, from left to right in the back:  Epipremnum ‘Lemon Meringue’, Aglonema ‘Solar Flare’, Spathiphyllum ‘Sophia’. Two in front from left to right: Alocasia azlanii and Cordyline ‘Mini Me’.

Epipremnum Lemon Meringue is a pothos or devil’s ivy with gold leaf margins. It is very easy to grow and can tolerate low light. Aglonema ‘Solar Flare’ also is easy to grow and can take low light and a bit of dryness — perfect for those who forget to water plants or travel frequently. ‘Solar Flare’ is variegated with white petioles (stems), almost like a bok choi Chinese cabbage. Spathiphyllum ‘Sophia’ (also known as peace lily) has variegated green leaves. Cordyline ‘Mini Me’ is a great tabletop houseplant. Given its small stature, it packs a punch of pink foliage, especially if given bright light. Alocasia azlanii has very dark purple, almost metallic colored leaves. It too is a small plant, perfect for tables or even terrariums.

In the photo above, from left to right in the back: Philodendron ‘Pink Princess’, Philodendron ‘Painted Lady’, and Epipremnum amplissimum ‘Silver Streak’. The two in front from left to right: Philodendron ‘White Knight’ and Philodendron ‘Golden Violin’.

Philodendron ‘Pink Princess’ is a climbing vine with bronze-green leaves splashed with pink. ‘Pink Lady’ has gold green foliage with pink petioles (stems). Epipremnum amplissimum ‘Silver Streak’ is an unusual pothos in that it has narrow, long green leaves. To me, its branching habit makes it look like an orchid. White Knight has white markings on green leaves. Philodendron ‘Golden Violin’ is coming soon; you may not see it on the website now. The new growth is golden yellow, changing to chartreuse. This is a climber that needs bright light, and the leaves get larger if grown vertically.

 

In the photo above, from left to right in the back:  Zamioculcas zamiifolia ‘Chameleon’, Aglonema spathomena, and Monstera standleyana albo-variegata. In front center is Tradescantia ‘Roxxo’.

Zamioculcas zamiifolia is a mouthful; most people just say “ZZ plant.” With ‘Chameleon’, the new foliage is bright yellow because the leaves do not have chlorophyll. This plant can survive in low light plant but you want to give it as much light as possible to encourage new growth, thus new yellow leaves. As the leaves age, the chlorophyll develops and the foliage becomes green. Aglonema spathomena looks like a spathiphyllum but there are no flowers. The foliage is variegated with dark and light green colors. Monstera standleyana albo-variegata is a creamy white variegated monstera plant. Unlike other monstera plants, the leaves do not have the Swiss cheese effect of holes in the foliage. Tradescantia ‘Roxxo’ is an upright form of tradescantia. The thick foliage is dark green with purple undersides.

Dieffenbachia ‘Cool Beauty’

For a fuller, bushy Dieffenbachia, try ‘Cool Beauty’ with green and white variegated leaves and white margins. This plant suckers (puts forth new stems) from the base. It can reach a foot tall — still a good height for a table.

Another new introduction that will appear on Costa Farms’ website soon is Alocasia ‘Jacklyn’. Jacklyn has very large, dark green, fuzzy leaves with reticulated stems (big word for color changes). This unusually hairy alocasia plant just screams ‘Amazon River’!

All of these plants would be great houseplants for your home. Explore their other plant collections on their website and sign up for their newsletter to learn of new plant introductions.

Streptocarpus: A Mouthful but Easy-to-Grow Flowering Houseplant

flowerIf you are looking for the perfect houseplant, try a streptocarpus. A mouthful I know but it is a beautiful flowering plant, cousin to the African violet but with more drama. These are easy to find now in the winter at local garden centers with houseplants.  It is unique, festive, and great gift for Valentine’s Day.houseplant

Native to Africa, streptocarpus is commonly called a Cape primrose. There are more than 135 species, and the size varies. The plants you see in the garden centers will have long, strap-like leaves with tubular flowers high above the plant. There are some though with only a single leaf that can range from a few inches to a few feet in length.

Grow these plants like you would grow an African violet. They need strong indirect sunlight by the window or fluorescent tubes. They grow best with day temperatures of 65 to 80 degrees and night temperatures between 65 and 68 degrees. They do not like heat so if you put them outdoors in the summer with your other houseplants, they may perish.streptocarpus

The soil should be evenly moist, but not wet. If you let the soil begin to dry out just a little bit between waterings, that would be ideal. Do not let water get on the leaves. There is specially formulated African violet soil which will work well for streptocarpus plants. They need to be fertilized with diluted balanced fertilizer. A balanced fertilizer has the same proportion of nitrogen, phosphorus, and potassium, the three numbers below the name of the fertilizer. To prevent a build up of fertilizer salts, periodically leach the plant by letting water run through the soil and out the drainage holes.

A streptocarpus is a type of a gesneriad, member of the Gesneriaceae family. These include the African violet, espiscia, columnea, sinningia, and aeschynanthus to name a few. If you really enjoy growing streptocarpus, try your hand at growing other gesneriads and consider joining the local National Capital Area Chapter of the Gesneriad Society.

Year of the Peperomia Houseplant

Peperomia ‘Hope’

This year is the year of the peperomia, a tropical houseplant. Actually, it is an “old-fashioned” houseplant, one that has been around for many years. What is new are the many types available now, each uniquely different. In fact, there is such variation in foliage color and structure, if there wasn’t a label on the container, you might not know it is a peperomia. There are only two things each plant has in common: thick, fleshy leaves and flowers that look like rat tails. Grown for its foliage, peperomia is relatively easy to grow, a great houseplant for beginners. Continue reading

Houseplants should be appreciated — they have a lot to offer us.  Houseplants improve air quality by removing chemicals and carbon dioxide and supplying oxygen. Houseplants provide a positive psychological impact by increasing memory retention and concentration and reducing stress. They add beauty and color and can be used as a structural component to divide a room. Continue reading

A Great Houseplant for the Winter: Anthurium

When I was young, we lived in Thailand and my mother (who grew up in Milwaukee) would buy plants and orchids from the market. I remember one houseplant in particular. The beautiful flowers were so waxy they looked like they had been polished with furniture polish. The red flowers would last for months. My mother of course did not speak Thai so we did not know the names of the plants but we enjoyed their exotic beauty. Now that I am older, I know the waxy plants are called anthuriums. Although I associate them with tropical Asian countries, they really hail from South America tropical environments.

Anthuriums are members of the Araceae or arum family. The “flower,” the red, heart-shaped part, is a modified leaf called a spathe. The actual flowers are tiny and appear in the center vertical structure called the spadix. The “flower” lasts a long time, making them ideal for cut flower arrangements.

As a houseplant, anthuriums can grow in low light conditions. However, the more light you can provide the more likely it will bloom throughout the year. It definitely does not like moist soil. Water when the soil is dry to the touch. Anthuriums are easy, low maintenance plants, perfect for the home and office.

Usually one sees red-flowering plants at the hardware store or nursery but pink, green and white, and purple colored cultivars are available. There is even a black flower cultivar called ‘Black Love‘. My plant was less than ten dollars at the local hardware store but it was very root bound in a 4-inch pot so check your plant’s roots after you purchase it.

Anthuriums as the perfect winter houseplant: the flowers last a long time and the plant has an exotic, year round appeal. Try growing this easy houseplant or purchase one as a hostess gift when you visit family and friends this year.
