Joshua Trees (Pictures)

Yucca brevifolia, or the Joshua tree, is one of the characteristic plants that occur in the Mojave Desert region. It is perennial and endemic to the Mojave, and considered central to many of the ecocommunities that make their homes in this desert. A joshua tree only produces its branch-like shoots when it manages to flower, and this may not happen for many years, depending on climate conditions. Because it generally requires more moisture for this process, Joshua trees can be found on higher elevations, on soil that is more likely to be penetrated by precipitation (Somerville).
