Orchids Have History In California

50218thumb
Breeding has done wonders with orchids.

It is funny how so many different plants get here from all over the world, and then become so popular so far from their natural homes that they seem to have always been here. It is now hard to imagine that some of the more popular cymbidium orchids actually came from tropical and subtropical Asia and northern Australia. Other orchids are from tropical Africa or South America.

As the Nineteenth Century turned to the Twentieth, orchids were popularized by those who profited from industry in the east, and then moved west to escape harsh winters. They arrived in the Mediterranean climate of the Santa Barbara region with resources to spend on outfitting luxury homes with comparably luxurious gardens and exotic plants. Orchids were a natural choice.

At homes in Montecito and Hope Ranch, cymbidium orchids were grown is mass plantings, and maintained by professional horticulturists. The popularity of orchids continued for decades. As the extensive orchid collections of England were threatened by the bombing and fuel shortages of World War II, collectors and horticulturists in California brought them here to be safe and warm.

Many of these refugee orchids were bred extensively by Californian horticulturists to produce many of the countless varieties that are now available. Production of blooming potted orchid plants and cut orchid flowers have become major horticultural industries in California. To this day, the Santa Barbara region produces more orchids than any other region in America. Modern tissue culture cloning technology has made it possible to propagate and grow more orchid plants at a faster rate than ever before. This makes them more affordable.

Even though mass plantings of cymbidium orchids are now rare, orchids are probably as popular as they ever have been, simply because they are so available to more people who can enjoy them. They are not limited to fancy gardens of luxury homes. Cymbidiums are still popular potted plants for sheltered porches. Small but flashy moth orchids are among the most popular of blooming potted plants for homes and offices.

Ornamental Pepper

50211
Colorful but not flavorful ornamental pepper.

The red, orange, yellow, purple, white or almost black fruit of ornamental pepper that naturally develops in summer can be seen at any time of year because the plants are grown in artificial greenhouse environments. The peppers are usually small and narrow, and stand upright above their glossy rich green foliage. Some are narrower. Others are a plumper. Technically, the fruit is edible, but it is not as flavorful as peppers grown for culinary purposes.

Because the plants are sensitive to frost, they are more often grown as houseplants than out in the garden. In the garden, they need shelter to survive as perennials. As houseplants, they need warm and sunny exposure in order to bloom and develop fruit. They should be watered regularly, but only as their potting soil is starting to get dry.

Overworked Plants May Recover Slowly

91218thumb
Some potted plants are real overachievers.

Landscaping and growing houseplants really is no way to bring nature closer to home. If it were up to nature, most of our gardens would be relatively bare. Most of the few native trees are less than ideal for home gardens. The few native annuals and perennials with colorful flowers bloom only briefly. Almost all native shrubbery is scrubby and not conducive to pruning. After all, most of us live in what would naturally be coastal chaparral.

This is why home gardens contain so many exotic plants from so many different climates and regions all over the world. These plants get pruned, shorn and mown in all sorts of unnatural ways. Most do better if watered unnaturally through naturally dry summer weather. Many crave unnatural fertilizer. Houseplants and a few others are confined to pots so that roots can not disperse like they want to.

Potted plants that are forced into bloom to decorate home interiors are the most unnatural of all. They are among the most extensively bred of plants. They are grown in contrived environments that coerce them to bloom whenever their blooms are needed. Poinsettias, lilies, azaleas, hydrangeas, kalanchoes, callas, miniature roses, chrysanthemums and some orchids are the more familiar of these sorts of plants.

They are certainly colorful by the time they leave the greenhouses they were grown in. By the time they come home, they are in the middle of full bloom. There is no work to get them to bloom. The work is in keeping blooms as healthy and as colorful as possible, for as long as possible. Most of these plants only want to be watered regularly, and are happy to keep their color for quite a while.

By the time they want fertilizer, blooming potted plants will have finished blooming. Sadly, at that time, most get discarded instead. Realistically though, such systematically abused plants can be rather ugly as they replace their greenhouse foliage with foliage that is better adapted to the garden. The process of forcing them into bloom is just too unnatural and difficult to recover from easily.

Yet, with enough patience and pampering, most blooming potted plants should eventually recover and adapt to a garden lifestyle. Lilies, callas and other bulb-like plants should be put aside in the garden while their foliage fades and eventually separates from the bulbs. The dormant bulbs can then be planted and allowed to grow into their new environments.

Hobbit’s Pipe

50107
Jade plant has some weird cultivars.

Good old fashioned jade plant has a few interesting cultivars (cultivated varieties) that exhibit variations of color, texture and form. Hobbit’s pipe, Crassula ovata ‘Hobbit’, is similar to classic jade plant in form and color. It is only slightly lighter green, and only a bit shorter. The succulent stems are just as plump and gray. The small and round-topped clusters of pale pink or white flowers that bloom sporadically are just as unimpressive. What is unique about hobbit’s pipe is the weirdly tubular foliage. Each leaf is rolled into a cylinder, with a hollow tip.

Mature plants do not often get much more than two feet tall and broad, although they have the potential to get twice as large. Because they are more sensitive to frost than other jade plants, hobbit’s pipe should be grown in sheltered spots, or pots that can be moved to sheltered spots through the coldest part of winter. Foliage that is too exposed during the warmest weather of summer can get roasted. Hobbit’s pipe can tolerate a slight bit of shade, so can be happy as a houseplant.

Seasonal Potted Plants For Christmas

91218thumb‘Tis the season for seasonal potted plants. These are not well established houseplant or potted plants that live out on porches and patios through the year. Seasonal potted plants are those that are purchased at their prime, allowed to live in our homes and offices while they continue to bloom or maintain their foliage, and then most likely get discarded when no longer visually appealing.

Poinsettia epitomizes winter seasonal potted plants. Florists’ cyclamen, azalea, holly, amaryllis, Christmas cactus and small living Christmas trees are other overly popular choices. All are grown in very synthetic environments designed to force optimal performance, with no regard to survival afterward. They are like cut flowers that are not yet dead. They are true aberrations of horticulture.

Technically, any of them can survive as potted plants, or out in the garden after they serve their purpose as appealing seasonal potted plants. Their main difficulty is that it is not so easy for them to recover from their prior cultivation, and adapt to more realistic environmental conditions. For now, it is best to enjoy them at their best, and try to maintain them at their best for as long as possible.

Eventually, they all experience a phase in which their original growth deteriorates to some extent, while they start to generate new growth that is adapted to the situation that they are in at the time. Christmas cactus are probably the most proficient at adapting, and becoming delightful houseplants. They are even likely to bloom occasionally, although not on any particular schedule for winter.

Holly, azalea and cyclamen can eventually get planted out in the garden. Most hollies grow into large evergreen shrubbery, but do not produce as many berries as they originally did. Azaleas are cultivars that were developed to be seasonal potted plants, so are a bit more finicky than those developed more for landscapes. Cyclamen can be added to pots of mixed annuals and perennials.

Living Christmas trees are not so easy to accommodate. Most are pines that need their space.

Kalanchoe

41112It is unfortunate that, like Easter lilies and poinsettias, most kalanches, Kalanchoe blossfeldiana, are enjoyed while actively blooming, and then discarded as their blooms fade. It is so easy to simply snip out the deteriorating flowers, and grow the small perennials plants for their appealing succulent foliage until they bloom again. They do not get much more than half a foot tall, so can stay in small pots indefinitely. They seem to prefer the porosity of clay pots. Because they can rot, they should be watered when the surface of the soil seems to be getting dry, and their drainage saucers should not be allowed to hold water too long. Kalanchoes like bright but indirect sunlight. They can be acclimated to direct sun exposure, but might seem to be somewhat stunted. If brought in before frost, they can be happy out on a patio. The clustered small flowers can be white, pink, red or bright or pastel shades of orange or yellow.

Horridculture – Fake Media

P90911This is no way to get the dirt on someone. There is no dirt involved. If there were, it would be referred to as ‘soil’. ‘Dirt’ is a term used by those who do not know any better.

Anyway, this is about the media that plants are grown in. It might be called growing media, potting media, potting mix or simply potting soil. Some in the horticultural industries might say that, because it is assembled from a variety of components that do not naturally occur together, growing media is synthetic. Because it lacks real soil, most of us refer to it simply as soilless.

Now, I am aware that not all media are created equal. The medium that we grew citrus in was much sandier than what we grew rhododendrons in. It was purchased already mixed specifically for citrus, and ready for use. The medium for the rhododendrons was mixed on site, with more coarsely shredded fir bark (from local mills), less sand and a little bit of perlite.

What I was not aware of, was just how perishable potting media purchased from retail garden centers are. Rather than drive out to the farm for a bin or two of medium, I purchased a bail of common ‘potting soil’ from a garden center about two years ago. I just happened to be there to pick up something else. The cost seemed worth avoiding an extra trip to the farm.

It actually was worth the cost. It did what I needed it to do for a time. The problem I am noticing now is that plants that were not planted or canned up (into larger cans) soon enough are now lacking the volume of medium they need. They need to be stuffed, which involves sliding them out of their cans to add a bit more medium to set them on top of, back in their cans.

The potting soil decomposed too readily. It is as if it rotted into muck that was rinsed through the drainage holes with watering. I suspect that there was more to the medium that the typical simple components. It probably contained significant volumes of compost derived from recycled greenwaste. I certainly have no problem with that. I just would have liked to know about it.

This little American persimmon seedling can stay in this half empty can until winter dormancy. Once dormant, it can be canned into a #5 (5 gallon) can, to resume growth next spring, before it even realizes that it is lacking medium. It will get a happy ending.

Guzmania

60713Just like potted chyrsanthemums, azaleas, hydrangeas and poinsettias, potted specimens of Guzmania magnifica are popularly purchased while beginning to bloom, enjoyed as house plants through a long bloom cycle, but then discarded as bloom eventually deteriorates. They are rarely allowed to produce new pups that can be divided and grown into fresh new plants to bloom later.

The bright yellow, orange, red or pink bloom stalks, as well as their rich green basal foliage, are so glossy that they seem to be plastic. The colorful parts of the blooms are pointy strap shaped bracts that arch outward from upright stalks. The leaves below have the same shape, but are longer, and more densely arranged in neat rosettes. Tiny flowers are mostly obscured by the bracts.

Guzmania magnifica, likes bright ambient sunlight without direct sun exposure, and can tolerate significant shade, especially if grown for only a few months while blooming. They seem to like misting, but probably do not not need it. They should be watered only weekly to every two weeks, when the surface of the soil seems to be getting dry. Too much fertilizer might scorch the foliage.

Ivy Geranium

90626This is one of the more traditional perennials for old fashioned window boxes, not only because it cascades downward to avoid obstructing associated windows, but also because, back before window screens were commonly available, the aromatic foliage was purported to repel mosquitoes. Ivy geranium, Pelargonium peltatum, is splendid for hanging pots and retaining walls as well.

The best bloom is usually later in summer or in early autumn, but sporadic bloom can continue almost throughout the year. The flowers are very similar to those of more common zonal geranium, but perhaps more abundant. The slightly more extensive color range goes beyond hues of white, pink, red and peach, to include rich burgundy, pinkish lavender and candy striped red with white.

The rounded and lobed light green leaves are rather succulent, so are easily damaged. Some cultivars have slight foliar halos (semicircular zones of darker color around the centers of the leaves) almost like those of zonal geraniums, but not quite as prominent. The thin and nearly succulent stems are easy to root as cuttings. Although fragile, they can sprawl or cascade as much as six feet.

Horridculture – What’s The Point?

P90403In this situation, the point is that all those pointed tips of the leaves of this awkwardly floppy century plant, Agave americana, are extremely sharp, extremely rigid and EXTREMELY dangerous. Those shorter teeth on the margins of the leaves are just as sharp and rigid, and are curved inward to maximize injury to anyone trying to get away from an initial jab. With tips that impale, and marginal teeth that slash, this is one very hateful perennial!

Another point is that this big and awkwardly obtrusive century plant is on a patio at a Mexican restaurant. Yes, it is in a public place where people get dangerously close to it. On Friday and Saturday nights, this restaurant can get quite crowded. Some within such crowds are inebriated, so are more likely to stumble about and bump into things that are best avoided. Those concrete slabs to the left are benches where people are often seated.

The third point is that the only remedy for this ridiculously bad situation is to remove the century plant. Chopping the leaves like those that were over the bench on the left only removes a few tips and teeth, but does not make the rest of the foliage significantly safer. Nor does folding the leaves inward, like those that are next to those that were chopped. Such abuse only makes the whole mess uglier. Now it is both dangerous AND ugly.

Now, who thought that putting the most dangerous of all perennials available into this public situation was a good idea?! (Cacti with inward curving spines and other plants that are more dangerous are not even available in nurseries.) Century plants are dangerously nasty even when small and young, so even someone who knows nothing about landscape design should have known better than this!
