Cypripedium parviflorum var. pubescens (Willd.) Knight

Greater yellow lady's slipper, Large yellow lady's slipper

Orchidaceae (Orchid Family)

USDA Symbol: CYPAP3

USDA Native Status: Native to U.S.

Borne terminally on a leafy stalk are 1 or 2 fragrant flowers with an inflated, yellow, pouch-shaped lip petal.

The Yellow Ladys Slippers form a highly variable population, and currently the large and small forms are regarded as separate species. The Small or Lesser Yellow Ladys Slipper (C. parviflorum), has very fragrant flowers, a lip petal only 3/4-1 1/2 (2-3.8 cm) long, brownish lateral petals, and a height of about 22 (55 cm). It is found mostly in limestone wetlands, only rarely as far south as the Appalachian mountains. Cherokee people made a preparation from the roots of these plants that was drunk as a treatment for worms.
