Cineraria

80314This is an extreme bloomer! Cineraria, Pericallis X hybrida, blooms with composite flowers, which means that each small daisy flower is really a whole bunch of minute flowers clustered together to look like a single flower. As if this were not impressive enough, a whole bunch of these composite flowers are clustered together on top of each big wide floral truss. They are not easy to ignore.

Blue, red, purple or pink bloom can be so profuse that the rich green basal foliage is only visible around the edges and below the domed trusses. Individual flowers usually (but not always) have white halos around dark centers. The soft leaves below are somewhat wide and rounded, with variably toothed margins. Big plants can get as high and wide as a foot. Some are more compact.

Cinerarias are most often obtained while blooming, enjoyed as potted plants, and then discarded after bloom, although with a bit of effort and shelter from frost and heat, they can be sustained as potted perennials to bloom again. They can be grown as short term bedding plants after frost in spring, but they require a slight bit of partial shade, regular watering and richly organic medium.

Potted Plants Going To Pot

80314thumbIt seems like such a waste that so many of the prettiest blooming plants are generally regarded as temporary. They are grown in the most synthetic of environments, forced into bloom, sold at their prime, and kept as potted plants just long enough to finish their bloom cycle. When their bloom deteriorates, they typically get discarded, or planted out into the garden where they rarely survive.

Poinsettias epitomize these flowering potted plants, which are known in the nursery industry simply as pot plants. Almost all of us have given or received them as gifts or decorated our home with them prior to Christmas. Although they are not considered to be annuals, few survive as houseplants, and almost none survive in the garden. No one wants to admit to what happens to the rest.

Okay, so it is not really a big loss. Poinsettias do not do well here anyway; and even if they survive, they are not as appealing in the landscape as they are as pot plants. What about all the others? Easter lilies, chrysanthemums, amaryllis, hydrangeas, orchids, azaleas, miniature roses, kalanchoes and even a few evergreens and living Christmas trees are all grown as forced potted plants.

It is important to be aware that all of these forced plants were grown in very synthetic environments, in which temperature, humidity and perhaps even day length were manipulated to coerce the plants to bloom, or for evergreens to be as lush as they are. Some were stunted with growth regulators. Recovering from such manipulation takes some time and effort, but for most, it is possible.

Of course, they all have their own personalities, and require different sorts of pampering. Some only need their old flowers to be pruned away, and will be able to produce new foliage that is adapted to their new environment. Amaryllis starts out without foliage, so has the advantage of making all new foliage after bloom. Chrysanthemum will eventually want to be cut back to favor new basal foliage. Easter lily foliage should be left while it dies back slowly until dormancy. New foliage grows next year.

Transvaal Daisy

80307There is some controversy about the identity of the flowers that Micky Mouse picks at the porch to present to Minnie Mouse when she answers the door. Some insist that they are Transvaal daisy, Gerbera hybrida. When they are not in black and white, the substantial daisy flowers are cartoon hues of yellow, orange, red, pink and white, sometimes with chocolatey brown or black centers.

Transvaal daisies are always available as cut flowers, but bloom best in cool spring and autumn weather in home gardens. Most garden varieties have single flowers on bare stems. Most cut flowers are semi-double. Double flowers that resemble zinnias, and spider flowers that resemble spider mums, are rare. Coarse basal foliage gets almost a foot high and a foot and a half wide.

Because the foliage is so vulnerable to snails, Transvaal daisy is usually grown in pots rather than in the ground or immobile planters. Besides, potted plants can be brought into the home or put in prominent spots while blooming, and then put out of sight between bloom. Transvaal daisy wants partial shade, regular watering and occasional feeding. It can take full sun exposure if not too hot.

Pots And Pans Need Cleaning

30918thumbThis is getting to be cliché. “While they are dormant through winter”, plants tolerate all sorts of abuse that would offend them at any other time of year. It applies to planting bulbs and bare root plants. It also works for pruning deciduous fruit trees and roses. It is a predictable seasonal pattern. Most winter gardening is contingent on dormancy. Processing potted plants is no exception.

Plants that have gotten too big for their pots should be replanted into larger pots. Any circling roots should be severed, just as if the plants were going into the ground. Unlike planting into the ground, potted plants require artificial media, known simply as ‘potting soil’. If larger pots are not an option, overgrown plants must at least be pruned to stay proportionate to their confined roots.

A plant that has been in a pot long enough for the media to decompose and settle might benefit from being ‘stuffed’. This involves removing the root mass from the pot, adding just enough media to the pot to support the root mass at the desired level, replacing the root mass on top, and then adding more media around the root mass to fill the pot. Exposed surface roots can be buried too.

Many overgrown succulents (not including cacti) can be replanted lower instead of higher. If settled, more media can be added on top. If all the foliage is clustered on top of bare stems, the stems can be cut and ‘plugged’ as new plants into pots of media, while the old roots and basal stems can be left to generate new stems and foliage. Newly plugged stems will generate roots by spring.

In the processes of potting, stuffing and plugging, while pots are empty, it would be a good time to scrub away mineral deposits from the bases and inner rims of pots. These deposits tend to accumulate just above the surface of the potting media, and where pots sit in water that drains from them. The pans or saucers that contain drainage water also accumulate mineral deposits. While plants are being processed, they can be groomed of deteriorating foliage and other debris.

Potted Plants For Christmas Color

80103thumbAfter all the Christmas decorations get put away for next year, and the Christmas tree eventually gets undressed from all its ornaments, and retired to the compost pile or greenwaste, all the pretty seasonal potted plants remain. Some will bloom, or at least maintain their current bloom, for months. Some might eventually get planted out in the garden. Others might stay potted in the home.

Poinsettias are the epitome of seasonal potted plants for Christmas. Their flashy red bracts last a very long time, even after the tiny yellow flowers are gone. Some are pink, white, pale yellow, peachy, marbled or spotted. They can be grown as foliar houseplants, but will not likely bloom next Christmas. If protected from frost in the garden, they get tall and lanky, and bloom in January.

Christmas cactus is an excellent potted plant either indoors or out where protected from frost. The pendulous growth cascades nicely from a hanging pot. It blooms in phases, but does not stick to a tight schedule. Amaryllis should also stay potted only because it does not do well in the garden over winter. Foliage that develops after bloom will die back next autumn before bloom next winter.

Holly and azalea can be planted directly into the garden where appropriate. Azalea will probably look shabby until it gets new growth. Cyclamen is a perennial in the garden, but dies back over summer. It just might come back with a surprise in autumn. Paperwhite narcissus is perennial too, but exhausts its resources on bloom, so takes a year or more to recover before blooming again.

Small living Christmas trees are more variable than they seem. Rosemary can either be kept potted and shorn, or planted into the garden and allowed to grow wild or into another form. Dwarf Alberta spruce can likewise stay potted or get planted into the garden, but needs no shearing. Both rosemary and dwarf Alberta spruce will want larger pots as they grow. Italian stone pine and Canary Island pine grow into large shady trees, so should only be planted into spacious landscapes that can accommodate them.

Parrot’s Beak

71213The Latin name is easy to confuse with the sacred flowers of an aquatic perennial from tropical regions of Asia, or a funny looking British sport coupe. Lotus berthelotii is a diminutive terrestrial perennial known as parrot’s beak. It gets only about a foot high, and spreads to only two or three feet wide. It cascades nicely from hanging pots, and is actually rarely planted out in the garden.

The bright reddish orange flowers bloom mostly in the warmth of spring and summer, but can bloom any time they are neither too hot nor too cool. They are about an inch long and ‘pea-shaped’, but they really look like parrot beaks. The finely textured gray foliage is comprised of small compound leaves that are divided into three or five very narrow leaflets that look like hemlock needles.

Parrot’s beak likes full sun and good drainage. It rots easily if soil is always damp. In hanging pots, it is usually sheltered from frost through winter, or can at least be moved to shelter prior to frost. Parrot’s beak can cascade nicely over the rims of urns of mixed perennials or annuals, but dies back through winter where such urns are too exposed. It is often grown as a warm season annual.

The Coffee Shoppe That Grows Its Own

P70928There are certain things that we expect to find in a coffee shoppe. Mainly, we expect to find . . . coffee. Yes, coffee, . . . duh. We can get all sorts of coffee beverages; hot, chilled, steamed, infused with things that have no business going into coffee. They have all sorts of cool sounding but strangely irrelevant Italian names that white people enjoy telling people of Italian descent how to pronounce. Yes, my name is Tony Tomeo; and I don’t want twenty cups of coffee with bread. Well, besides the coffee beverages, there are plenty of coffee beans; all sorts of roasts. I do not know of any coffee shoppe that grows any of the beans that it sells, but there is nice coffee shoppe in Felton, The Mountain Roasting Company, that grows coffee trees.

Yes, that is unique. I noticed a few years ago that besides the typical Ficus benjamina, there are three large coffee trees. They look similar to the Ficus benjamina, but are a bit less refined, and lack the braided trunks. They grow up to the ceiling before getting cut back to stumps to start the process all over again. The Ficus benjamina do not grow that well; but the coffee trees are happy enough to bloom there.

I have not asked how they get pollinated. I really do not know how coffee flowers get pollinated in the wild. Somehow, they make a few fruits, known as coffee cherries, with viable coffee beans inside. The seeds get collected, germinated, and potted for customers who have an appreciation for growing something unique. Small coffee trees can now be found in well outfitted nurseries, but it would be so much cooler to grow one that was grown at a local coffee shoppe.

I am embarrassed to say that I do not know how to grow coffee trees. I think of them as tropical plants, but I really do not know. Just because they are cultivated closer to the tropics does not mean that they originated there. I do believe that they are understory trees, that prefer to live in the partial shade of larger trees. Old text, as well as a few not so old gardening books from the 1960s, describe them as houseplants. There is not much mention of them after that. They only recently started appearing in nurseries. I like when old traditional plants make a comeback, particularly if it happens to be an alternative to a boringly common plant like Ficus benjamina.

Houseplants Bring The Outdoors In

70927thumbPhilodendrons, dracaenas, ferns, palms or any sort of tropical foliage inside our homes only create an illusion of closeness to nature. Naturally, these plants live in very different climates, mostly thousands of miles away. Not only do they have no business in our homes; they have no business on the North American Continent. Some can live in the garden, but only with unnatural watering.

They are only known as houseplants because they ‘can’ live in the house. Almost all are from tropical regions; and most are understory plants that naturally live in the shade of larger trees. They work nicely as houseplants because they tolerate the shade of home interiors. Because they are from tropical regions, they have no concept of winter, so do not need chilling for winter dormancy.

The disadvantages to their tropical heritage is that they are confined to domestic lifestyles here. Many would not survive frosty winter weather. Some might survive, but would not be happy about it. Others would not like the aridity (lack of humidity) during the summer. Houseplants that get moved out to the garden for part of the year must be grown in pots so that they can be moved back in.

While inside, there are no natural predators to control the insects that feed on houseplants. Scale and mealybug can proliferate enough to not only damage houseplants, but to also make a mess of their sticky honeydew below the houseplants they infest. Spider mites can proliferate where dust accumulates on foliage. That is why houseplants sometimes like to be rinsed by a gentle rain.

Since they are confined to pots, houseplants must be watered more carefully than plants that get to disperse their roots out in the garden. Some large Boston ferns and spider plants may need quite a bit of water to be applied very regularly. Some dracaenas, palms and ficus trees may want to get slightly dry between watering. As soil deteriorates, old plants might need to be repotted.

Houseplants are grown for their lush evergreen foliage, and such lush foliage can be sensitive to fertilizer toxicity. Even if fertilizer is applied lightly, toxins can eventually accumulate if fertilizer is applied very regularly. This problem is usually corrected with repotting. However, plants that never need to be repotted might like to be taken outside to get water rinsed through their potting soil.
