2-product description

Bletilla is a temperate, terrestrial genus of orchids containing 9 species distributed through China, Japan and Taiwan and Vietnam. The name is actually a diminutive of Bletia because of the resemblance between the two genera even though Bletia is a New World genus. The genera Jimensia Raf. and Polytoma Lour. ex Gomes are generally included into Bletilla. This genus is abbreviated Ble in trade journals.

The pseudobulbs resemble spreading corms which usually sit at ground level. Each pseudobulb generally bears several pleated leavesaround 40cm long. The racemes of flowers emerge from the center of the years new growth before it is mature, during spring and early summer. The flowers vary in color from white to purple, and all species have four pollinia. The tubers resemble a horn or claw. They are grayish-white or yellowish-white in appearance, with concentric rings and brown rootlets. They have a hard texture and do not break easily.
