Bletillas


Bletilla

A genus of nine or ten species of terrestrial orchids, occuring in E Asia. Bletilla sriata is an important wound herb in traditional Chinese medicine and was first described in medical literature in c.CE500. It is an attractive plant for shady borders in mild areas. Variegated forms are popular in the East. They are more tender, and are often grown in pots and given protection in winter. Bletilla is named after Don Louis Blet, a Spanish botanist.

Deciduous, terrestrial orchid with flattened, underground pseudobulbs and pleated leaves, to 50cm (20in) long. Loose spikes of magenta, occasionally white, flowers, 3cm (1¼in) across, appear in late spring.
