Habitat / Range
Moist forests, bogs and meadows in the montane and subalpine zones; frequent on the coast, infrequent in NW BC and E of the Coast-Cascade Mountains south of 55 degrees N; N to AK, E to AB and S to WY, ID and CA.
A shade-tolerant, submontane to montane, Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs on fresh to very moist, nutrient-medium soils within boreal, wet cool temperate, and cool mesothermal climates; its occurrence decreases with increasing elevation and continentality. Scattered in dense coniferous forests on water-shedding and water-receiving sites; often associated with Blechnum spicant, Gaultheria shallon, Hylocomium splendens, Rhytidiadelphus loreus, Plagiothecium undulatum, and Vaccinium alaskaense. Characteristic of friable Mors and acidic Moder humus forms.
