The saguaro grows only in southern Arizona, in California along the Colorado River and in the northern Mexican state of Sonora. It can live more than 200 years, attaining heights of 30 to 40 feet; a few exceptional ones exceed 50 feet. Its blossom, the state flower, appears in May and June. Native Americans use its fruit for food and as a beverage base.
In addition to protecting the saguaro and other desert vegetation of the Sonoran Desert, the park's Saguaro West district has rock formations decorated with Native American petroglyphs and designs.
