Dendrobium rigidum

Dendrobium rigidum is found in Australia and New Guinea. Plants usually grow on mangroves in swampy coastal lowlands in New Guinea and commonly grow in mangrove swamps but are also found on trees along creeks and on rock faces and ironbark trees in low mountains and dry savannas, sometimes considerably inland from the coast in Australia.  They grow from sea level to 2,300 feet (0 to 700 meters). It blooms sporadically during the year and usually blooms several times, with the main flowering in spring. It is a very slow-growing species. It is best grown mounted, but it can be in a shallow bulb pan or hanging basket. Do not use sphagnum moss. Air movement is critical. Repot in the spring.
