Simmondsia chinensis (Link) C.K. Schneid.
Jojoba, Goatnut, Quinine Plant, Coffeeberry
Simmondsiaceae (Jojoba Family)
Synonym(s): Buxus chinensis, Simmondsia californica
USDA Symbol: sich
USDA Native Status: L48 (N)
This attractive, gray-green shrub is often considered evergreen but technically is deciduous with persistent leaves. Inconspicuous flowers occur on short axillary stems and are followed by green, acorn-like fruits on female plants. Stiff branched for a low mound shape; jojoba grows 4 1/2-6 ft., or more, tall. Bluish-green, medium-size shrub with low, broad appearance and leathery leaves. Very widely spreading.
Jojoba is emerging as a potentially important desert crop species. Its fruit is about 50 percent oil, of a quality similar to that of sperm whale oil. Unlike many other oils, it does not degrade by bacterial activity. It can be used in cosmetics, lubricants, in cooking, and as a wax for cars, while the pulp remaining after oil extraction can be fed to animals.
