Bamboo orchid

Description

Arundina graminifolia, the Bamboo Orchid, produces pinkish flowers at the top of tall canelike pseudobulbs. It's the only species in the genus. The plants are quite tall; they'll reach at least hip level, possibly over your head, and their vegetative resemblance to bamboo can be uncanny. The long pseudobulbs have leaves alternating along their length, similar to Epidendrum orchids. The flower stems, which emerge from the top of the canes, produce several flowers sequentially, so that there will be one at a time over an extended period. The flowers are white with a purple-to-pink lip, and shaped similarly to a Cattleya orchid flower. They are 2-3 inches across (5-8cm), and can appear for much of the year, especially in summer.
