They are sold as root-less tubers in a bag. In Canada it is found from Labrador to British Columbia, and northward to the Northwest Territories, typically in coniferous forest. The truth is that they will probably begin growing right away in Florida since it will too warm to keep them dormant. The thick rhizome has flattened, bulb-like internodes and a vigorous root system. They are born on a thick fleshy stem in a lose spiral, 3 to 7 in all, and becoming smaller, eventually ending as floral bracts as they ascend the flower stalk. Today it is being mass produced and recently has made it onto the world market. These do not necessarily represent juvenile plants, but may rather be adults “taking a rest” from a heavy flowering/seeding cycle. Known for growing into large, clumping colonies and having yellow crested lips. Keep your potted orchids off the ground, so pests can't easily crawl into them. TERRESTRIAL ORCHIDS FOR SOUTH FLORIDA prepared by John McLaughlin* and Joe Garofalo* Orchids can be broadly categorized into three basic types depending on their growth characteristics: (1) epiphytic orchids survive attached to trees (or rocks - lithophytes) producing a sequence of shoots from a basal rootstock. Hey dude, I was stoked. Talk about frustrating! So again, we can see that diversity within any category of plants is often extreme, and generalizations are not adequate in describing them.Probably some of the best known terrestrial orchids are in the genera Bletilla, Cypripedium, and Orchis. It grows in moist rich woods. Here’s a video showing all the varieties covered in this article in my garden in southern Japan. Third, this orchid appears to have a dependency on mycorrhizal fungi even throughout adulthood. As already said, the plant itself is smaller in size and also less robust. Many more are challenging – the vast bulk of the popular genus Cyripedium, many of the acidic bog species, and most of the tropical jewel orchids all need more care and attendance to than a typical tropical orchid. Snails and slugs are another bane of this plant, and unless diligently controlled, will be the end of them in short order. The hair-like petals are held directly backward The column is long and arching. I grew this species in Gainesville, Florida and had problems keeping them dormant in February due to warm days – they would always begin growth and then we’d have a frost and they’d get damaged. The bulbous rhizomes can be packaged for some months, completely rootless, and yet when planted they will grow on and even flower.
If you have a native forest, or forest-like condition in the outside garden, and you live near natural populations, you may try this one in the open garden.
Of course not all terrestrial orchids are from temperate climates, in fact, they can be found as far north as the Arctic Circle and all the way down to the very south end of Patagonia. I had a friend in the UK who had a similar problem with this plant and after planting them in full sun they started to grow and flower like weeds. Plants don’t like that treatment, but they can endure it and within a couple seasons of planting even thrive. Sterile plants mostly bear a single, broad leaf with no significant above ground stem showing. Beyond that, I wonder how well they would do for you in your tropical climate. The lip is slipper-like, similar to a lady slipper (genus Cypripedium), but more elongated with a frilled front plate with upward curling margins. The long sepals are held in a triangle and are undulating. Although it has always just been one stem with three leaves – I found a good-sized corm underneath. The flower stalk, occasionally up to 15 cm tall, but often much shorter, begins growth once the cold of winter has abated.
The leaf margins are also distinctly uneven, almost toothed, not unlike some members of the genus Liparis. Finally, these plants are so small that they cannot endure much competition from neighboring plants including grasses, any type of ground cover, spreading bushes, or indeed even vigorously growing mosses. hi Tom a nursery in Belgium is selling a variety of bletilla called cerulia .Have you heard of this variety or is this something new? Recently though, a split was made – those that generally flower in the fall without a basal rosette of leaves are now in the genus Diplodium, while the winter/spring flowering species that retain their leaves when in bloom remain in Pterostylis. It is nowhere truly common, and is often overlooked. I knew you where thinking about and working on this project for some years now but teh result is great. Some contrary info: I read from Allan Summers at Carroll Gardens that it perfers semi-shade, and that indoors it supposedly blooms in February. A pair of broad glossy leaves ascend from a pseudobulb that sits at ground level. Ground orchids flower year round and with the right conditions, they grow for years. They also are a bit smaller than the normal type, at least in the plants I’ve grown. The flower of P. nutans alba is of course the main interest since it is truly pure white, and like the normal green flowered type, it is transparent as well. This plant is very similar looking to Liparis kumokiri, however, when not in flower L. kumokiri is a larger plant with more broad leaves while L. krameri has more elegantly tapering leaves.
None in that genus are cold hardy, being found only in subtropical to tropical forests and grasslands. While normal P. nutans is a near weed if grown properly, this little white flowered plant is more gracile and trickier to maintain. Five of the flower parts are nearly identical in size and shape, two petals and three sepals, splayed out in a star-like pattern. I would like to plant them in my garden on Siesta Key in FL. In time plants became more distributed and the reality of this flower became less legend, and more real. The pollina are bright green, almost electric looking. Ironically, while this species is so easy to grow and is available at big box stores the world over, it also is very rare in the wild these days. This little beauty is truly remarkable, and if you are a terrestrial orchid nut like me, once you’ve seen them, you’ll be hooked. Here’s a brief article about a truly lilliputian orchid, Listera makinoana. If you have it in a pot indoors, put it in a window behind a curtain. The trap then slowly releases and the fly escapes with no prize (Pterostylis produce no nectar), but with luck the pollen of the flower attaches to its back.
The genus Bletia has members that rival or exceed Bletilla in beauty and they should do very well in your climate. I have seen one growing in a bonsai pot that has virtually no soil anymore – the plant’s bulbous rhizomes piled on top of each other like rocks, veritably overflowing the pot. In Japan plants are in danger due to climate change since populations are confined to high mountain forests that are undergoing rapid warming. It shares many attributes with that species including its overall habit as well as habitat choice. Look for them where bulbs are sold. Plants in shadier areas tend to be more pale yellow. The plant is small, no more than 20 cm tall, the flower spike included. Thank you! Still, every time I find one of these little plants in the field my heart skips a beat – there it sits on the forest floor like some lost precious jewel. C. bulbosa v. americana – found across the entire boreal region of North America from the Atlantic to Pacific, as well as the mountainous regions of the western US (in Canada it is widespread in forested regions, in the US from northern Maine, Vermont, Michigan, Wisconsin, Minnesota, South Dakota (Black Hills), Montana, Idaho, Wyoming, Washington, Utah, Colorado, New Mexico, Arizona, Alaska; historically N.Y. (last seen in 1969) and New Hampshire. Mari. That finally changed in 2019 when I finally beheld a lovely population growing on a limestone plateau in northern Kyushu, Hiraodai Karst Plateau.
