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.
