A matted plant, often grayish-haired, with basal leaves and round heads of tiny, reddish or purplish to cream flowers on long, erect, leafless stems.

Alpine plants are generally dwarf; plants growing in sagebrush are usually taller. Flowers vary from cream to yellow when young; as they age, they may become reddish or purple.
