Cypripedium montanum (Mountain lady's slipper)
Glase, Terry

Cypripedium montanum

Cypripedium montanum Douglas ex Lindl.

Mountain Lady's Slipper

Orchidaceae (Orchid Family)


USDA Symbol: CYMO2

USDA Native Status: L48 (N), AK (N), CAN (N)

A leafy plant with few stems in a clump, and near the top 1-3 white and dull purple bilaterally symmetrical flowers, 1 in each upper leaf axil.

Most Lady's Slippers are handsome plants, all the more charming because of the mystique and romance surrounding Orchids. So many species have been dug up that most are now rare in the wild. Although many enthusiasts try to cultivate these plants as ornamentals, they will die in the garden.
