Joshua Tree
Yucca brevifolia
  
About Joshua Tree (Yucca brevifolia) 17 Nurseries Carry This Plant Joshua Tree is a native tree-like monocot that grows from southern California to Utah. Although it grows to tree size, it behaves like a Yucca in every other respect. It tends to grow in the high desert at elevations from 1600-6600 feet, though it grows up to 11,000 feet in the White and Inyo Mountains. It is exposed to lower winter temperatures than other parts of southern California. In locations where it is common, such as the Mojave Desert, it forms large colonies known as Joshua Tree Woodland. The leaves are stiff, long (6-9 inches), narrow and sharply pointed on the tips. The flowers are greenish-white held on a long panicle and pollinated by a moth. Around 25 species of birds use Joshua trees as nesting sites. Because of its slow growth rate and its very specific requirements, it is not often used in typical residential gardens. However, it could be a great choice for a larger garden in a desert or semi-desert area.
