Habitat Requirements

The plant grows on gravelly, sandy loams associated with talus in alpine fellfield above 3,322 meters (m) (10,900 feet [ft]) in elevation to 3,780 m (12,400 ft) (USDI 1983, 1987). The plant has a known global range of 85.59 hectares (ha) (211.49 acres [ac]) (Dexter 2007). The plant exists mainly on talus slopes as a primary successional species.

Reproductive Strategy

The plant reproduces vegetatively via rhizomes, indicated by the high percentage of plants growing in dense clusters (Phillips and Peterson 1980). However, sexual reproduction also occurs, evidenced by numerous, scattered, individual plants and the observation of mature fruits with dense flowers (Phillips and Peterson 1980). Pollinators have been observed on the flowers, but we do not have any information regarding pollinator species. Flowering is from August to early September, fruits mature in mid-September, and the plant becomes winter-dormant in early October (USFWS 1983). The most recent surveys, described below, found a total of over 36,000 ramets of the species along 2 transects (Fowler 2009).
