Yucca baccata

Spanish Bayonet grows from southeastern California through Utah and along the Texas Mexico Border. "The large fleshy fruits are an important fruit among the native Californians, especially the Navajos who eat them raw or roasted. Often these fruits are dried, ground, and made into small cakes to be used during the winter. Leaf fibers of this species are used in basketry." Benson and Darrow, Trees and Shrubs of the Southwestern Desert.
