Ecology & Habitat

Habitat

Montane populations in Wyoming are on dry, rocky, often disturbed ridges and in meadows with volcanic substrates at 2200-3300 m elevation. Other Wyoming populations are along sandstone ridges with scattered Limber pine (Pinus flexilis) and Utah juniper (Juniperus osteosperma) at elevations of 1770-1800 m. The Utah plants are growing in gravelly soils on limestone outcrops at 2620 m.
