Orchids in the genus rattlesnake orchid are sympodial epiphytic, lithophytic or, rarely, terrestrial herbs with pseudobulbs, each with one or two large, stalked leathery leaves. A large number of small flowers are arranged in two ranks along a thin, wiry flowering stem that emerges from the top of the pseudobulb. There is a large, papery bract at the base of each flower. The flowers are white, cream-coloured, yellowish or pinkish with a concave dorsal sepal and smaller petals. Most are native to areas from tropical and subtropical Asia to the southwestern Pacific.
Water:
Rattlesnake orchid thrives in humid tropical environments and requires consistent humidity with weekly watering. As an epiphyte, it prefers well-draining soil and benefits from frequent misting. Its indoor cultivation meets its high humidity needs, essential for its optimal health.
Propagation:
Propagation of rattlesnake orchid involves division and keiki development. Success requires high humidity, indirect light, and warm temperatures (18–25°C / 64–77°F). Use airy substrates like fir bark or sphagnum moss, divide pseudobulbs during repotting, and maintain humidity while avoiding direct sun. Establishment may take time.
