Calopogon

Calopogon, grass pink, is a genus of terrestrial orchids (family Orchidaceae). The generic name is from Greek and means "beautiful beard", referring to the cluster of hairs adorning the labellum. The five species are native to the eastern United States, eastern Canada, Cuba and the Bahamas. The genus Calopogon is abbreviated Cpg in trade journals.

Calopogon, like many other orchids, is an indicator species for good remnant hydrology. This means that their presence is an indication of high-quality ground and surface water. Most species of Calopogon frequent wet, sunny swales, bogs, and the edges of marshy areas, and associate with ferns, sedges, grasses and forbs. Calopogon oklahomensis has been observed in drier areas than Calopogon tuberosus would prefer.
