Cypripedium acaule, the pink lady's slipper or moccasin flower, is a species of flowering plant in the orchid family Orchidaceae native to eastern North America. It is currently the provincial flower of Prince Edward Island, Canada, and the state wildflower of New Hampshire, United States. Indigenous peoples traditionally used this plant for medicinal purposes.
