Crag aster is an attractive perennial with one to several erect or ascending stems from 4-15 cm high. The numerous leaves are narrowly elliptical, measuring 5-15 mm long and 1-3 mm wide with entire margins.
The flower heads are solitary atop the stems. The involucre measures 7-11 mm high with shingled bracts, covered with short glandular hairs. The rays are pink, blue or violet, with about 8 to 13 thin rays, each measuring from 6-15 mm long. The central disk measures about 7-13 mm wide and is yellowish. Crag aster flowers from May to July.
Crag aster is found on dry, open places, often with sagebrush, from the lowlands to 3300 m.
Crag aster may be found from south-central Oregon east to Powell Co., Montana, south to Utah and Mono County, California.
