Cypripedium is a genus of 47 species of hardy, lady's-slipper orchids native to temperate and colder regions of the Northern Hemisphere.
Some grow in the tundra in Alaska and Siberia, which is an unusually cold habitat for orchids. They can withstand extreme cold, growing under the snow and blooming when the snow melts. But, in the wild, most have become rare and close to extinction, due to an ever shrinking natural habitat and overcollection. In the late 20th century, only a single plant of Cypripedium calceolus survived in Britain.
Common names include slipper orchid, lady's slipper, mocassin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes and whippoorwill shoe. An abbreviation used in trade journals is 'Cyp'.
The genus has a long history of use, dating back 2,500 years to the Far East, where they were used medicinally. Several orchid species thought to be extinct in the United Kingdom including one native species in this genus have been found in habitat and are currently the subject of aggressive conservation efforts to protect and restore these showy plants to their native ranges
