Variety: none[2]


P. ciliaris is a perennial forb/herb of the Orchidaceae family that is native to North America.[1]


P. ciliaris is native to the eastern United States, reaching as far west as Texas, as well as Ontario, Canada.[1]



Native habitat for P. ciliaris includes bogs, swamps, marshes, wet sandy barrens, thickets that border streams and ponds, moist woods, wet meadows, praires, and deep humus of upland forests.[1][3]

Shaded areas or partial sun is ideal for this orchid. Also, slightly acidic soils are ideal.[1]


P. ciliaris has been observed flowering in July and September.[4] When flowering it prefers full sun; it has been observed that there are less dense flowers when lacking full sun.[5]

Fire ecology

Populations of Platanthera ciliaris have been known to persist through repeated annual burns.[6]

Diseases and parasites

Slugs, snails, and cutworms are known to be pests for the P. ciliaris.[1]

Conservation, cultivation, and restoration

Due to habitat loss, harvesting, and land management practices such as fire suppression, there has been a decrease in P. ciliaris. It has been listed as threatened in Connecticut, Florida, Maryland, Michigan, Ohio, and Pennsylvania. It is also listed as endangered in Illinois, Indiana, new York, and Rhode Island. Canada is considered to be locally extinct.[1]
