Joshua Tree - Yucca brevifolia
Most common in the Mojave Desert, this is a low to middle elevation southwestern tree. It grows fairly rapidly, given the dry habitat, and can achieve a height of nearly 50 feet. The bark is gray-to-brown and consists of plates and furrows. The crown of mature trees is broad with many stout branches. The leaves are more than a foot in length, evergreen, and needle-shaped with a sharp point; they are serrated on the edges. The creamy-white flowers are borne in long panicles; flowering is dependent on available moisture. The fruit is somewhat fleshy and contains many seeds.
