Dry to moist, mossy forests in the lowland, steppe and montane zones; var. occidentalis - common W of the Coast-Cascade Mountains; var. americana - common E of the Coast-Cascade Mountains; circumpolar; var. occidentalis - N to AK and YT and S to ID and CA, Eurasia; var. americana - N to AK, YT and NT, E to NF and S to ME, VT, MI, WI, MN, SD, NM and AZ.
A shade-tolerant/intolerant, submontane to montane, circumpolar forb (transcontinental in North America). Occurs on moderately dry to fresh, nitrogen-medium soils within montane boreal, cool temperate, and cool mesothermal climates. Rare to occasional (locally abundant on eastern Vancouver Island and Queen Charlotte Islands) in mossy forest understories on water-shedding sites; its occurrence increases with increasing continentality. Characteristic of coniferous forests.
