Ecological Indicator Information

A shade-intolerant, subalpine to alpine, Western North American evergreen shrub distributed equally in the Pacific and Cordilleran regions. Occurs in alpine tundra and subalpine boreal climates on fresh to very moist, nitrogen-poor soils. Common in non-forested (heath and krummholz) and open-canopy forested communities on water-shedding sites with prolonged snow-lie. Often grows with Rhododendron albijlorum and Vaccinium membranaceum. An oxylophytic species characteristic of Mor humus forms.
