A very shade-intolerant, submontane to montane, Western North American deciduous shrub distributed more in the Cordilleran than the Pacific region. Occurs in continental climates on very dry to moderately dry, nitrogen-medium soils. Scattered and often plentiful on disturbed water-shedding sites within cool temperate, cool semiarid, and dry cool mesothermal climates; its occurrence increases with continentality. Common in early seral communities in the coastal-interior ecotone. When forming a shrub layer it hinders regeneration and growth of shade-intolerant conifers. Symbiosis with nitrogen-fixing bacteria enhances the supply of available soil nitrogen. Characteristic of moisture-deficient sites.
