Sagebrush is a woody shrub with hairy, silvery leaves that stay green all year round. It's normally 2-4 ft high but can be taller. It has a gray twisted trunk and branches with stringy, fragile bark. Small yellow flowers appear in late summer or early fall. It has a deep taproot that can gather water from far below the surface.
Sagebrush is usually found in cold deserts with sandy or powdery soil and has a sharp odor (turpentine and camphor), especially after it rains.
