What does Aerangis look like?
Aerangis orchids are small plants that often grow on trees (epiphytic) or rocks (lithophytic). They have six to ten fleshy, evergreen leaves with parallel veins. Their flowers are large for the plant’s size, waxy, and shaped like stars, usually in shades of white, cream, or yellow. The flowers are arranged on a long stem, and each one has a flat lip similar to its petals and sepals. A long, nectar-filled spur extends from the flower, sometimes longer than the flower itself. At night, the flowers release a pleasant fragrance.
Where does Aerangis come from?
The genus Aerangis was described in 1865 by Heinrich Gustav Reichenbach, with Aerangis flabellifolia as the type species. Its name comes from Greek, meaning 'air urn,' which refers to the shape of the flower’s lip. Aerangis species are native mostly to tropical Africa, but some are found on the Comoro Islands, Madagascar, and Sri Lanka. These orchids are adapted to humid, forested environments, growing mainly on trees or rocks.
