Jojoba
Simmondsia chinensis
  
About Jojoba (Simmondsia chinensis) 12 Nurseries Carry This Plant Jojoba; Goatnut (Simmondsia chinensis) is a common native shrub that grows in Southern and Central California, primarily in the Peninsular Range and Sonoran Desert regions. It is moderately fast growing and long-lived. It grows in a rounded form to a height of 7 feet, with active growth during the summer and fall. Flowers are yellow and bloom in the late spring. Male and female flowers are borne on separate plants, the "goatnut" fruits only being found on female plants with male plants nearby. Leaves are medium green, and remain on the plant throughout the year. It tends to grow in rocky and sandy soils, at elevations from 0-4900 feet.

Plantations of jojoba have been established in a number of desert and semi-desert areas, predominantly in Argentina, Australia, Israel, Mexico, Peru and the United States. It is currently the Sonoran Desert's second most economically valuable native plant (overshadowed only by Washingtonia filifera, California fan palms, which are used as ornamental trees).

Jojoba prefers light, coarsely textured soils. Good drainage and water penetration is necessary. It tolerates salinity and poor-nutrient soils. Soil pH should be between 5 and 8. High temperatures are tolerated by jojoba, but frost can damage or kill plants. Requirements are poor because jojoba plants do not need an intensive Weed problems only occur during the first two years after planting and there is little damage by insects. Supplemental irrigation could maximize production if rainfall is less than 400 mm. There is no need for high fertilization, but, especially in the first year, nitrogen increases growth.
