This plant grows in subalpine and alpine climates, often in moist areas, such as woodlands and meadows around streams and lakes. It also occurs on tundra and other cold, dry, exposed areas. It occurs on gravel bars and scree. It is sometimes a pioneer species, colonizing land in the primary phase of ecological succession, such as roads and bare land turned over during frost heave. It has been observed regrowing early in recently burned areas in Grand Teton National Park. It also grows in vegetated areas. Plants occurring in harsh conditions are smaller than those in more favorable sites.
