Nursery contributed plant descriptions

This beautiful tuberous ginger relative from Nepal has lance-shaped leaves and orchid-like pink to mauve flowers partially concealed by the upper leaf sheaths. Part shade to part sun in a moist but well-drained soil
"Roscoea is a small genus of late spring/summer growing plants of the ginger family, Zingiberacea. They have a growing point from which a cluster of thickened roots descend, somewhat like a Dahlia but in minature form. The leaves are reminiscent of a minature sweet corn, with flower at the apex, which to my eye is somewhat orchid like (thinking Masdevallia) with one large decending petal and several smaller petals above and beside the main petal. They originate mainly from India, Nepal and China." The above description is from PacificBulbSociety.org , an excellent informational resource! Full size bulbs. Should be dug up and brought inside for the winter in colder climates (if it snows, its cold). Mine have overwintered in zone 8, Arizona. Needs fertile soil, moisture, and shade.
