Ecological Indicator Information

A shade-tolerant/intolerant, sub montane to subalpine, transcontinental North American deciduous shrub (sporadic in the Pacific region). Occurs predominantly in continental boreal and cool temperate climates on very dry to moderately dry, nitrogen-medium soils; its occurrence increases with increasing continentality. Common in semi-open forests on water-shedding sites; scattered on the leeward side of Vancouver Island; plentiful in the coast-interior ecotone. Often associated with Calamagrostis rubescens, Linnaea borealis, and Paxistima myrslnites. Symbiotic with nitrogen-fixing organisms. Characteristic of continental forests.
