Big Sagebrush

Big Sagebrush (Artemisia tridentata)

Big Sagebrush (Artemisia tridentata) is the Nevada state flower and one the most abundant woody plants found throughout the Great Basin and is an icon of the American west.

Big Sagebrush can grow up to 10 feet in height, but tend to average less than 3 feet. It is considered an evergreen, although its leaves are more of a grey/silvery color. The leaves are wedge shaped and tend to have three lobes at the end. They also have a distinctive odor when crushed--an odor that is emblematic of the the wild west. The flowers are inconspicuous and yellow, they bloom in late summer--1 plant can produce up to 1 million seeds. The plants prefer dry plains, mesas or rocky areas with deep, well drained soils. They tend to be found at elevations between 3,000 and 10,000 feet.

Big sagebrush communities are vital to the Great Basin because they provide an important winter food source for wildlife, including deer and pronghorn, although it tends to be avoided by horses and cattle. Sagebrush also provides nesting cover for sage grouse and other birds, it helps prevent soil erosion and protects animals against harsh environmental conditions such as wind, rain and intense sun. The importance of big sagebrush communities for wildlife habitat is widely recognized. Species of concern that rely upon sagebrush communities include the Greater Sage-Grouse and Pygmy Rabbits.
