Artemisia tridentata

Artemisia tridentata, commonly called big sagebrush, Great Basin sagebrush or simply sagebrush (one of several related species of this name), is an aromatic shrub from the family Asteraceae. It grows in arid and semi-arid conditions, throughout a range of cold desert, steppe, and mountain habitats in the Intermountain West of North America. Big sagebrush and other Artemisia shrubs are the dominant plant species across large portions of the Great Basin. Sagebrush provides food and habitat for a variety of species, such as sage grouse, pronghorn antelope, grey vireo, pygmy rabbit, and mule deer. Several major threats exist to sagebrush ecosystems, including human settlements, conversion to agricultural land, invasive plant species, and wildfires. Native Americans have used the plant medicinally. It is also useful as firewood....read more on Wikipedia.
