Bulbophyllum auricomum

A small epiphytic Bulbophyllum from low-elevation forests of Myanmar, Thailand, Sumatra and Java, grown for its nodding racemes (about 22 cm long) of many fragrant flowers. Flowering falls in late autumn to early winter, the cooler, drier part of the monsoon year, so it is best grown warm and wet in summer and brighter, cooler and drier in winter. Published habitat detail is thin, so the targets below come from the lowland monsoon climate of its range.

Where it grows wild

Low-elevation forest in continental and western Malesian Southeast Asia. Like most Bulbophyllum it grows on trunks and branches; the northern part of its range (Myanmar and Thailand) has a strongly seasonal monsoon climate with a dry, cooler winter, while Sumatra and Java are wetter and less seasonal.

Described only as low-elevation forest; no elevation range was found and no measured records are available.
