Fringed Sagebrush
Artemisia frigida
Aster family (Asteraceae)

Members of the Artemisia are characterized by their distinctive pungent sage aroma and foliage which is silvery green because of a mat of fine white hairs. Presence of Fringed Sagebrush is often considered an indicator of overgrazing or disturbance. "Frigida" is Latin for "cold"; the species was first collected in Siberia in 1803.
