Crested fringed orchid (Platanthera cristata) is a state-threatened terrestrial orchid found in wet prairies, seepage bogs, ditches and wet pine flatwoods. Its bright yellow to light orange flowers bloom in summer, peaking in August. Bees are thought to be its primary pollinator.
Crested fringed orchid’s range extends along the coastal plain westward to Texas and north up to New Hampshire. While considered rare, it tends to grow in small colonies resulting in patches of bright color. It is known to hybridize with other Platanthera species including the White fringed orchid (P. blephariglottis), Yellow fringed orchid (P. ciliaris) and Chapman’s fringed orchid (P. chapmanii). It also closely resembles the latter two species.
