Mojave Yucca (Yucca schidigera)

The Mojave Yucca is a small evergreen tree which flourishes in the Mojave and Sonoran deserts of California, Arizona and Nevada. The Yucca’s most noticeable characteristic is its large branches and bayonet like leaves. The rigid leaves are typically dark green in color and can reach up to 4 feet in length. I can also personally attest that they are sharp at the pointy end.

The Mojave Yucca can reach a height of 16 feet and that mass is supported by a trunk which is up to 12 inches in diameter. The Yucca is typically found on rocky slopes and below 4,000 feet in elevation. The plant blooms are very similar the Joshua Tree and it will send up a cluster of white bell shaped flowers from the top of the stem. This cluster is short lived, but can reach and additional 120 cm in length.

Also like the Joshua Tree, the Mojave Yucca depends upon the white pronuba moth for pollination. This moth will deposit its eggs in the ovary of the Yucca Flower and there by cross pollinate the tree. The moth lavae hatch and consume some the the seeds in a wonderful example of natures balance.

The Mojave Yucca also provided utilitarian purpose for the Native Americans. They utilized the leaves as a source of cordage, which could be woven into blankets, rope, hats and mattresses. The roots of the Yucca contains high levels of saponin, and could be made into a pulp and used as soap The flowers and fruit were a food source and could be eaten both raw and roaster. The black seeds could be ground into flour.

The yucca, with its sharp pointed leaves offer wonderful defensive habitat for snakes, lizards, rabbits, birds and other desert animals.
