Cypripedium is a genus of terrestrial orchids in the Orchidaceae family. It includes about 50 species, most of them quite hardy, which can be found in America, Europe, and Asia. In the northern part of their distribution, temperate slipper orchids are found from sea level into the lower hills, occupying coniferous forests, mixed deciduous woodlands, bogs, fens, grasslands or prairies. Some of them can survive through harsh winter conditions, fearlessly withstanding temperatures below -22°F (30°C). Farther south they usually inhabit montane woodlands and grasslands at higher elevation.
