The Bulbophyllum orchid genus is the largest in the orchid family, with over 1800 species, and it’s the third largest genus of plants of any kind. Species of this genus are distributed worldwide, with the greatest diversity in Papua New Guinea, where they are thought to have originated. These sympodial plants have conspicuous pseudobulbs with a single, folded leaf at the top. Flower stems emerge from the base of the pseudobulb, and have a mobile labellum or lip, that can rock back and forth.

Many species form clusters of flowers arranged in a semicircular pattern; this makes them look totally different from the species that emphasize a single, large flower! Other species arrange their flowers sequentially along the stem. Most flowers of this species are pungent: many smell like rotting carcasses or dung, as they are pollinated by flies. Fortunately, there are other species that don’t stink.

They do well mounted on slabs of bark, but the rhizomes will tend to wander everywhere. Growing them mounted also requires more humidity, and daily misting and spraying. For a potting mix, sphagnum moss is used. Its absorbency means that the roots have plenty of air, but are constantly given very high humidity. They generally don’t like to dry out too much, so it’s best to water as they approach dryness. They like high humidity, about 70% and like intermediate light, about 2000 footcandles or a bit higher.
