Facts About

Rose pogonia is found over an unusually broad temperature range, from northern Canada to southern Florida. It is a distinctive orchid, with a pink flower and a single clasping leaf half way up the stem. The specific name (ophioglossoides) refers to the fact that Adder's tongue ferns (Ophioglossum), have a similar single leaf half way up the stem. The two unrelated plants also share similar habitat requirements.

Habitat

Anthropogenic (man-made or disturbed habitats), bogs, fens, meadows and fields, wetland margins (edges of wetlands)
