About

Jojoba ( ; botanical name: Simmondsia chinensis) – also commonly called goat nut, deer nut, pignut, wild hazel, quinine nut, coffeeberry, and gray box bush – is an evergreen, dioecious shrub native to the Southwestern United States and northern Mexico. Simmondsia chinensis is the sole species of the family Simmondsiaceae, placed in the order Caryophyllales. The name "jojoba" is a hispanicization from hohohwi in Oʼodham, not to be confused with the almost homographic but unrelated "jujube" (Ziziphus zizyphus) commonly grown in China.

Jojoba is grown commercially in its area of origin and in other (semi-)arid regions to produce jojoba oil, a liquid wax ester extracted from its seed. Jojoba oil is highly valued in the cosmetics industry.

Where it grows

The plant is a native shrub of the Sonoran Desert, Colorado Desert, Baja California desert, and California chaparral and woodlands habitats in the Peninsular Ranges and San Jacinto Mountains. It is found in southern California, Arizona, and Utah (U.S.), and Baja California state (Mexico).

Uses

Jojoba foliage provides year-round food for many animals, including deer, javelina, bighorn sheep, and livestock. Its seeds are eaten by squirrels, rabbits, other rodents, and larger birds.
