Anyone who’s seen specimens from the Smithsonian Orchid Collection knows that this most diverse and species-rich plant family can display truly bizarre yet strangely beautiful forms. Literally every day, some improbable flower comes into bloom in our greenhouses. But there is one plant that invariably causes jaws to drop when viewed in full bloom. Most onlookers agree it is among our most spectacular and prized orchid species in the collection.
Habenaria medusae is a terrestrial orchid from monsoonal habitats in Indonesia and mainland southeast Asia. Producing a basal rosette of leaves from a subterranean corm, the plant is fairly nondescript until it sends up a 20-inch inflorescence bearing ten to twenty or more truly astounding flowers. Most prominent is the outstanding lip, composed of finely dissected, radially arranged fringe reminiscent of Medusa’s head of snakes, from which it gets its name. One might ask why such a lip evolved in the first place; in this case it is still somewhat of a mystery. Thought to be moth-pollinated because of its white color, sweet evening fragrance and nectar spur, the deep fringe is actually a fairly commonplace feature of moth flowers. Though no one knows exactly why, something about these deeply fringed flowers acts as a highly effective attractant to moths.
Habenarias are known for being difficult to cultivate, intolerant of poor or chemically treated water, and needing a strict, dry winter dormant period. They rot easily if watered during their dry season. Despite its sensitive nature, the Smithsonian’s specimen has proven to be more amenable than most to cultivation and has bloomed three times since being purchased as a small bulb from a vendor from Singapore at the World Orchid Conference. This year the plant was selfed (pollinated with its own pollen) to create more seedlings of this delightful species and also crossed with a related species with a deep coral pink lobed lip in the hopes of producing flowers with a colorful medusa lip.
