Arundina graminifolia is a species of orchid and the sole accepted species of the genus Arundina. Arundina graminifolia is a terrestrial, perennial orchid with reedy stems, forming into large clumps growing to a height between 70 cm and 2 m.
Arundina graminifolia is a terrestrial orchid with foliage that resembles a bamboo, hence the common name of bamboo orchid. It is native to southeast Asia. Reedy stems grow to 5-6' tall to form large clumps. Stems are clad with narrow linear grass-like leaves (each to 4-8" long) with sheaths that wrap the stems. Cattleya-like flowers (to 2-3" across) bloom throughout the year, but more heavily in summer. Each flower features white or pink tepals and a ruffled pink to rose labellum with a yellow center. Each flower is followed by a ribbed seed capsule which splits open when ripe to release its powdery seeds into the wind. Synonymous with and formerly known as Arundina bambusifolia and Bletia graminifolia. Genus name comes from the Latin word arundo meaning a reed. Specific epithet means having grass-like leaves.
