Platanthera ciliaris, commonly known as the yellow fringed orchid, yellow-fringed orchid, or orange-fringed orchid, is a large and showy species of orchid. It grows in "acid soil of hillside seepage bogs" in the longleaf pine landscapes of the Gulf Coast.[1] Like many species in these habitats, including flatwoods, it is dependent upon recurring fire to create open conditions.[2] Further north it is found in bogs, but even here it may be dependent upon fire to create open conditions. [3]

It is pollinated by large butterflies, mostly swallowtails.[1]

The species is at risk in some areas from loss of habitat and collecting. For example, it is endangered in Michigan.[3] It has been recorded from extreme southern Ontario, but is now thought to be extirpated.[4]
