{{redirect|Sagebrush|other uses of the word|Sagebrush (disambiguation)}} '''''Artemisia tridentata''''' (also called '''sagebrush'''/'''common sagebrush''', '''big sagebrush''', '''blue'''/'''black sagebrush''' or '''mountain sagebrush''') is a [[shrub]] or small [[tree]] from the family [[Asteraceae]]. Some botanists treat it in the [[segregate (taxonomy)|segregate]] genus ''Seriphidium'', as ''S. tridentatum'' (Nutt.) W. A. Weber, but this is not widely followed. The [[Sagebrush (plant)|vernacular name "sagebrush"]] is also used for several related members of the genus ''[[Artemisia (plant)|Artemisia]]'', such as [[Artemisia californica|California Sagebrush]] (''Artemisia californica''). It is a coarse, hardy silvery-grey bush with yellow [[flower]]s and grows in arid sections of the [[American West|western]] [[United States]] and [[Western Canada]]. It is the primary vegetation across vast areas of the [[Great Basin]] desert. Along rivers or in other relatively wet areas, sagebrush can grow as tall as 3 m (10 feet), but is more typically 1-2 m tall. Sagebrush has a strong pungent fragrance, especially when wet, which is not unlike [[common sage]]. It is, however, unrelated to common sage and has a bitter taste. It is thought that this odor serves to discourage browsing. Sagebrush [[Leaf|leaves]] are wedge-shaped 1-4 cm long and 0.3-1 cm broad, and are attached to the branch by the narrow end. The outer and wider end is generally divided into three lobes (although leaves with two or four lobes are not uncommon), hence the scientific name ''tridentata''. The leaves are covered with fine silvery hairs, which are thought to keep the leaf cool and minimize water loss. Most of the leaves are carried year-round, as sagebrush tends to grow in areas where winter precipitation is greater than summer precipitation. Sagebrush flowers in the late summer or early fall. The flowers are yellow and are carried in long, slender clusters. Sagebrush is not fire-tolerant and relies on wind-blown seeds from outside the burned area for re-establishment. {{Inc| Artemisia tridentata, Nutt. Sage Brush.
