The Joshua tree is a type of yucca plant that grows in the Mojave Desert of the United States, and it can live as long as 150 to 200 years. This tree's height can range from 20 to 70 feet, and its trunk diameter can range from 1 to 3 feet. During the 19th century, the Mormon pioneers gave this tree its name because of their association of the tree with Joshua the prophet.
The Joshua tree is a succulent with the scientific name of Yucca brevifolia, which belongs to the Agave family. For pollination, the Joshua tree depends on the yucca moth. The tree produces fruit and disperses seeds via wind and animals. The Joshua tree provides both shelter and sustenance for a variety of desert insects, birds and reptiles. These trees grow in the Joshua Tree National Park and are protected by law.
