Sagebrush is a hardy, silver-gray shrub that grows wild across the dry plains and deserts of the American West. If you've ever seen a classic Western movie with wide-open landscapes dotted with dusty, aromatic bushes, you were probably looking at sagebrush. It thrives in places where other plants struggle: hot, dry regions with sandy soil and little rainfall.

The plant gets its name from its resemblance to culinary sage, though they're different species. When you crush sagebrush leaves, they release a sharp, distinctive smell that many people associate with the open range. This scent comes from oils the plant produces to protect itself from being eaten by animals.

Sagebrush plays a crucial role in its ecosystem. The greater sage-grouse, a large bird species, depends on sagebrush for food and shelter. Pronghorn antelope browse on it during winter. Native American tribes used sagebrush for medicine, ceremonies, and even weaving.

The word sagebrush also appears in phrases describing the Western frontier. A sagebrush rebellion refers to conflicts over how Western land should be used, while sagebrush country simply means the wide, open spaces where this tough plant dominates the landscape.
