Calopogon

Description

Calopogon is a genus of terrestrial orchids with about 15 species native to North and Central America. The name Calopogon is derived from the Greek words “kalos” meaning beautiful and “pogon” meaning beard, referring to the beard-like tuft of hairs on the lip of the flower. These orchids have a single, slender stem that ranges from 10 to 50 cm in height and produces one to several flowers at the end of a long stalk. The flowers are usually pink or purple with yellow or white markings, and they bloom in late spring to early summer.
