Joshua Tree (Yucca brevifolia) is a tree yucca specie. This unique plant is an iconic symbol of the Mojave Desert. It has good cold hardiness and can be planted throughout the milder winter areas of the Western US. Be patient, as this slow growing beauty can take many years to reach the mature size so often photographed in the wild. Find a hot, sunny spot with poor, infertile, quick-draining soil for planting. Water regularly (a deep soaking every few weeks during the growing season) will help it to grow a little more quickly. Grown from seed collected near St. George, UT.
