Facts About

Loesel's wide-lipped orchid has a wide distribution in North America, Europe and Asia, but is apparently uncommon to rare in most of its range. It is found in moist to wet open soils in meadows, fens, shorelines and disturbed areas. Hydrology may be the most inportant factor in limiting growth and reproduction in this species.

Habitat

Anthropogenic (man-made or disturbed habitats), fens (calcium-rich wetlands), lacustrine (in lakes or ponds), meadows and fields, shores of rivers or lakes
