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,[4] and the state wildflower of New Hampshire, United States.[5]

Indigenous peoples traditionally used this plant for medicinal purposes. For example, Algonquin peoples, who form part of the larger cultural group known as the Anishinaabeg,[6] traditionally used C. acaule to treat menstrual disorders.[7] Due to population decline, harvesting for medicinal purposes is no longer recommended. As C. acaule takes many years to go from seed to mature plant, the gathering of seed-bearing specimens is presently unsustainable.[8]
