Cephalanthera, abbreviated Ceph in horticultural trade, is a genus of mostly terrestrial orchids. Members of this genus have rhizomes rather than tubers. About 15 species are currently recognized, most of the native to Europe and Asia. The only species found in the wild in North America is the Phantom Orchid or Snow Orchid C. austiniae. Ecologically, this species is partially myco-heterotrophic. Some of the Eurasian species hybridise.
