Bogs, shorelines, streambanks, wet meadows and moist forests in the lowland and montane zones; common in SW and SE BC south of 55degreeN, infrequent in SC BC, rare in N BC; amphiberingian, N to AK and S to CO, ID and CA; E Asia.
A shade-tolerant/intolerant, submontane to subalpine. Asian and Western North American sedge distributed equally in the Pacific and Cordilleran regions. Occurs on wet to very wet, nitrogen-medium soils within boreal, temperate. and cool mesothermal climates. Scattered in non-forested, semi-terrestrial communities (less frequent in forest understories) on water-collecting sites; often with Lysichitum americanum. Characteristic of wetlands.
