Joshua Trees (Yucca brevifolia) grow in the Mojave Desert of southwest California, Nevada, Utah and Arizona. It is said that Mormon pioneers named this species of Yucca "Joshua" Tree because it mimicked the Old Testament prophet Joshua waving them, with upraised arms, on toward the promised land. The legendary rock band U2 also helped put Joshua Tree National Park on the map of pop culture.
