Ecological Indicator Information

A shade-intolerant, subalpine, Asian and Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs in alpine tundra and subalpine boreal climates on very moist to wet, nitrogen-medium soils. Its occurrence increases with increasing latitude, and decreases with increasing continentality. Common in high­elevation, heath-like or low­shrub communities on water­shedding and water-receiving sites. Associated with Cassiope mertensiana, Luetkeapectinata, and Phyllodoce empetriformis. Characteristic of subalpine communities.
