View an image of a Bitterbrush leaf. Bitterbrush (Purshia tridentata) has small, silvery leaves adapted for its life on sunny hillsides and rocky slopes at 3500 to 9000 feet. It is called the favorite browse of mule deer, and it is also eaten by elk. The seeds are eaten by pocket gophers, chipmunks, and ground squirrels.
