Butterfly Orchid

I always assumed that the Florida butterfly orchid, Encyclia tampensis, got its name because it looks like a stylized butterfly, but I likened it to a butterfly for the way its flowers dance and flit  in the slightest breeze. Reading up on the plant for this post, I found that this resemblance to the fluttering of the butterfly's ephemeral wings often is cited as the source of the name, so I wasn't as original as I had thought!

Encyclia Flowers Dance in the Breeze

Encyclia is a smallish genus in the orchid family. It once was included in the Epidendrums, and fairly recently taxonomists have split out Prosthechea from Encyclia, so the classification probably will change again.

The name "Encyclia" comes from a Greek word meaning "to encircle." That's because the outside of the lip of these orchids wraps around the column, the reproductive structure in the center of the flower. The Florida butterfly orchid was first discovered around the Tampa area, hence its specific name, "tampensis," but its range is much larger, from the Keys to north-central Florida.

Though it varies pretty widely according to growing conditions, Encyclia tampensis is a  small plant. One or two leaves are produced from a  swollen storage organ called a "pseudobulb," which can be round or more elongated. The pseudobulbs are anywhere from a quarter-inch to at most an inch in diameter, and a half-to-one and a half inches tall on average. The somewhat succulent leaves can be a few inches to 5 or 6 inches or more in length, depending on the individual plant and its habitat. Each pseudobulb produces one blooming spike, and slowly declines over the next 3-5 years. Some people remove the dead pseudobulbs. Otherwise they either fall off, or just become incorporated within new growth. Left to its own devices Encyclia tampensis eventually forms a mound-shaped colony.

Encyclia tampensis Pseudobulbs and Leaves

The butterfly orchid flowers from late spring through August, but its peak season is now - June. This plant in bloom can be spectacular A flowering branch can have up to 45 flowers, but the plant is lovely even with fewer blossoms. The flowers last a long time - about a month. I don't get too many seed pods, so the pollinator - a wasp or a bee - evidently doesn't visit our yard regularly or in great numbers.  The flowers close much more quickly when pollinators are active, so some people bring their Encyclias indoors to enjoy the blooms longer.

Seed Pods

 I bring some smaller colonies onto the patio to be enjoyed from inside the house, but leave my largest colony outside. It's happy where it is, and I can see it from the patio. Also, a large colony tends to have creatures living in it, and I hate for anoles to get lost in the house. They're next to impossible to catch, and inevitably end up dead. There might even be a small snake hidden amidst the pseudobulbs and leaves, and they don't do well inside either.

Encyclia tampensis Flowers

The bilaterally symmetrical flowers are an inch to inch-and-one-half wide and tall. Petals and sepals are a green-bronze, sometimes more  yellow, sometimes tinged with brown or maroon. They are quite attractive, though my attempts to render them in watercolor or colored pencil usually end looking muddy. The lip is clear white with a magenta or lavender splotch in the middle. The variety 'alba' has lime-green petals and sepals and an all-white lip.

The flowers also have a delightful fragrance, which comes and goes during the day - the pattern with most fragrant blossoms. It sometimes is described as vanilla- or honey-scented. To me, it has an undefinable light sweet odor, not the heavy tropical fragrance of a gardenia.

Though once common, Encyclia tampensis now is neither common nor rare, and is protected by the state. Its natural occurrence continues to be depleted by illicit collection and habitat destruction. Collectors, even those harvesting plants from private property, and sellers must have a state permit to be legal. Fortunately there are several reputable nurseries offering this plant, so there really is no need for taking them from the wild unless it is a salvage operation.

This plant often is found in or around swamps. It likes to grow on trees such as oaks, pond apples, buttonwood, cypress, and more rarely, pine. Instructions for its care tend to emphasize maintaining high humidity, but I would temper that advice. The plant also occurs in scrub, and as a Florida native is adapted to seasonally dry periods. I have seen colonies in scrub that were so stressed they were purple-gray, but they still were very much alive. It should not be placed in potting soil. It's an epiphyte - the roots serve primarily to anchor it, not for nutrient and water uptake. Some of my butterfly orchids are in pots, but the substrate is lava rock, charcoal and large wood chips. The plant likes to attach itself to the terra cotta as well.

My plants get very little TLC, and do just fine. In the dryest weather I check them for scale. They are in filtered light - protected from the worst sun exposure, but still in conditions bright enough to make blooms. Those in too much shade grow ok, but don't flower. If they are lucky they get a sprinkle of diluted orchid fertilizer once or twice a year. If I notice that there aren't many new pseudobulbs forming, I remount the plant, relocate it, give it a little more attention, or all 3. I don't worry that much about watering them during the dry season, but if we get prolonged hot and windy spells, I will give them an occasional sprinkle.

A virtually pest-free, no-care native plant with spectacular long-lasting flowers and delightful fragrance  - does it get any better than this?

7-Year Apple

7-Year Apple, Genipa clusiifolia, is a wonderful native plant that should be used more in south Florida. It doesn't make sense that it can be hard to find, because it should be a gardener's and landscaper's dream plant. Though it bears individual flowers intermittently all year, the "big event" occurs in  spring and summer. Then it produces intensely fragrant white, star-shaped flowers over the entire shrub. Flower buds and the tips of petals are apricot-colored. Even out of flower, its large (up to 6 inches long), evergreen glossy leaves make it a good choice for a medium-to-large sized shrub/small tree. The smooth leathery leaves are slightly turned under along the margins, which lowers the transpiration rate.

7-Year Apple - Staminate Plant

 A lot of plants are said to be trouble-free, but this one really is. Nothing bothers it. It grows freely on the back side of the beach dunes here. It is extremely drought-and-salt tolerant, untroubled by diseases, and free of insect pests. It is listed as the larval host of the Tantalus Sphinx Moth, but ours has never shown any evidence of chewing. In general it is also wind-resistant. Ours came through Hurricane Wilma in 2005 with minimal damage. Irma, last September, though, tore it apart.

When we moved to our house on a barren lot I broke a cardinal rule of gardening - don't place shrubs and trees too close to each other. I knew the theoretical mature size and spread of the things I was planting, but could not visualize how the bare slips I was committing to the earth would ever reach those dimensions. Besides, I didn't expect everything to thrive. I planted a Jamaica Caper, the Genipa, and a Coontie (Zamia pumila) on 3-4-foot radii in the vicinity of a medium Christmas Palm. Then later, I added a Lignum Vitae (Guajacum sanctum) which had outgrown its pot because there seemed no other place to put it.

 For a few years everything in the garden was lovely, and then everything took off at once. The Coontie has formed a massive clump at least 5 feet in diameter, and the Jamaica Caper is 12-15 feet tall. The Lignum Vitae, which already had developed a spreading form in the pot, spread even more in competition with the others. The Genipa started getting shaded out. Genipa bears most of its leaves in clusters at the ends of its  branches, so it is sort of hollow "inside," but the growth is typically dense and compact enough to protect it from wind. The branches on ours had become so elongated and spread out that Irma's winds ripped the shrub apart. It is badly disfigured now, and the problem of too little space for too many plants remains. But it is blooming so profusely now that I can't bring myself to be rational and ruthless.

My main reason for loving it is its incredibly fragrant flowers. By now  the Jamaica Caper has ceased flowering, but the Genipa is still going strong, and I go out at least once a day, but usually more, just to get my "hit" from the fragrance. Butterflies, skippers, other small insects, and probably moths, love the flowers too. Ours started blooming in March and is still not slowing down.

Gulf Fritillary and Genipa

The plants are dioecious - that is each individual plant has either "male" (staminate) or "female"(carpellate) flowers. The staminate plants produce clusters of flowers, while carpellate flowers appear singly. When you buy a Genipa, it's the luck of the draw which one you get, same as with hollies. You'll get fruit only with a carpellate plant close enough to a staminate plant to be pollinated.

Immature Fruits

The immature fruit isn't quite so "deco neon" - I'm no master of Photoshop Elements! In spite of the name, the fruit takes about a year to mature. Fruit in various states of maturity can be found on the same bush. It starts green, turns yellow, and then dark brown when ripe. It is about the size of a Comice pear. It is vaguely edible, but not palatable.

Fallen Ripe Fruit

I've never eaten a fermented prune, but that's what came to mind when I tasted Genipa. The fruit is little more than a pulpy sac containing numerous seeds, which are said to be emetic. Mockingbirds apparently have developed a trick of pecking a small hole in the fruit and eating the inside goodies - leaving an empty sac still hanging on the branch. Other wildlife, especially raccoons, eat the fruit as well.

7-Year Apple is native to Cuba, the Bahamas, Turks , Caicos, Bermuda, and southern Florida. It grows in sandy or rocky substrates. Why do garden centers concentrate on exotics that need coddling when there are natives like this?
