Bletilla striata is a hardy and very easy-to-grow terrestrial orchid with upright, heavily textured, iris-like, 18"" long x 3"" wide green leaves and forms a slowly spreading clump. In early spring, stalks to 30"" tall of very small lavender with a dark purple lip, cattleya orchid-like flowers are held atop the foliage. The rhizomes spread forming a nice colony. Bletilla striata grows best in moist-to-damp soils in 1-6 hours of sun. Hardy in zones 5-9.
