Description
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).
Jojoba is endemic to North America, and occupies an area of approximately 260,000 square kilometers (100,000 sq mi) between latitudes 25° and 31° North and between longitudes 109° and 117° West.

Moderate
Simmondsia chinensis, commonly known as jojoba, is a drought-tolerant evergreen shrub native to the arid deserts of the southwestern United States and northern Mexico. Prized for its oil-rich seeds that produce a liquid wax used in cosmetics and skincare, jojoba is a slow-growing but long-lived plant that can survive over 100 years. Seeds require scarification pretreatment to overcome dormancy caused by the hard seed coat.

Soaking — 24 hours
Soak seeds in warm water (not boiling) for 24 hours, or after scarification allow water to cool to room temperature over 18-24 hours. This softens the hard seed coat.

🔨
Mechanical scarification
Lightly scarify seed coat with sandpaper or file, or use hot water treatment by soaking in 82°C water then cooling naturally for 18-24 hours. Mechanical scarification (sandpaper) significantly improves germination rates.

Additional notes
Scarification is highly recommended as jojoba seeds have a hard outer coat that resists water penetration. Combined mechanical and water scarification yields best results.
Substrate & Container
Recommended substrate
Well-draining sand or loamy soil, alkaline preferred. Mix of sand, perlite, and potting soil works well.
Recommended container
Small pots 2-3 inches in diameter. Cover with plastic to retain moisture until germination.
Growing Tips
Seeds need scarification (mechanical or hot water) to improve germination rates significantly. Plant in alkaline, well-draining soil and keep soil moist but not waterlogged. Provide plenty of light and maintain warm temperatures (70-80°F/21-27°C) for best results. Germination may be slow and sporadic; be patient as seeds can take up to 6-8 weeks. Use larger seeds when possible as they germinate faster and produce more vigorous seedlings. Seeds produce either male or female plants (dioecious), so both are needed for seed production.
