Yucca brevifolia is in the family Agavaceae. Commonly known as the Joshua Tree, it is only found in the Mojave desert of California, Nevada, and Arizona. The Joshua Tree is one of the fastest growing desert plants, able to grow up to 50 feet tall and produce roots that reach dozens of feet down into the soil. Individuals can live for hundreds of years and flower multiple times throughout their life. The production of flowers at the apical meristem causes the Joshua Tree to form branches in order to keep growing, giving this plant its iconic shape.
