Ecological Indicator Information

Very shade-intolerant, submontane to montane, Pacific North American forb; occurrence decreases with increasing continentality. Species occurs in hypermaritime to submaritime cool mesothermal climates on wet to very wet, nitrogen-medium soils. Occasional in semi-terrestrial communities (less frequently in open-canopy forests) on water-collecting sites with surface groundwater table and accumulations of peat. Characteristic of wetlands.
