Mountain lady’s slipper is in the Orchidaceae (orchid family), one of the largest and most diverse of all plant families.
Though mountain lady’s slipper, like most other species in the family, produces beautiful flowers, collection of wild plants is strongly discouraged. Most mountain lady’s slipper populations are very small, can easily be decimated and transplanted wild plants rarely survive. Some states have laws protecting wild orchid populations.
Stems of mountain lady’s slipper arise 2 to 7 dm (8 to 28 inches) from short rhizomes. Leaves are sessile, often sheathing, and generally broadly elliptic in shape, 5 to 15 cm (2 to 6 inches) long and up to 7 cm (2.8 inches) broad. The inflorescence typically includes one to three flowers each subtended by a green leafy bract.
