Joshua Trees (Yucca brevifolia) only grow in California, Arizona, Nevada and Utah, mainly in the Mojave Desert. The name Joshua tree was coined by early Mormon pioneer settlers because the tree shape appeared to them to be reminiscent of Joshua’s hands reaching up in prayer. The Cahuilla Native Americans of the region call the tree "hunuvat chiy’a" or "humwichawa". Joshua Tree is also the name of the Joshua Tree National Park and a community outside this National Park.
