This terrestrial orchid has 3 to 7 oval to lance-shaped leaves. Unusual flowers almost 4 inches long, with a rose-pink floral globe under a pair of twisted petals, are borne singly or in pairs on upright stems in summer.
Noteworthy Characteristics:  Suitable for a shady rock garden or woodland garden. Native to eastern North America.
Care:  Grow in moist, fertile, leafy, humus-rich soil that is neutral to acidic. Prefers a sheltered site with light dappled shade or partial shade.
Propagation:  Divide carefully in early or mid-spring and replant immediately. Plant some of the soil from the root ball with each division.
