Platanthera leucophaea
Also called Eastern Prairie White Fringed Orchid, Prairie White Fringed Orchid, Eastern Prairie Fringe Orchid
A rare, long-lived terrestrial orchid of moist tallgrass prairies, sedge meadows and fens in eastern North America, with showy white flowers. It is a protected species and is not grown in home gardens as a routine houseplant.
Platanthera leucophaea, commonly known as the prairie white fringed orchid or eastern prairie fringed orchid, is a rare species of orchid native to North America. It is a federally threatened species, protected since October 30, 1989 under the Endangered Species Act of 1973. In Canada, it has been listed endangered under Schedule 1 of the Species at Risk Act since 2005. In 2014, the International Union for Conservation of Nature assessed it as "least concern."
Platanthera leucophaea is found in moist to wet tallgrass prairie, sedge meadows, fens, and old fields. For optimum growth, little or no woody encroachment should be near the habitat. Historically, the eastern prairie fringed orchid is found primarily in the Great Lakes Region with isolated populations in Maine, Virginia, Iowa, and Missouri. A historic record exists for Choctaw County, Oklahoma. The plant has not been observed in Oklahoma in the past 150 years. The major factor in the decline of the eastern prairie fringed orchid has been a loss of habitat due to grazing, fire suppression, and agricultural conversion.
