Germinating Jacaranda Seeds: Soil, Light, and Temperature Requirements

Starting Jacaranda mimosifolia from Seed

Jacaranda seeds are papery and winged. They germinate quickly with warmth and light.

Sowing Method

1. Sow on the surface of moist potting mix; barely cover (⅛ inch).
2. Keep at 75°F (24°C); use a heat mat if needed.
3. Cover with clear plastic to retain humidity.
4. Germination in 10–15 days.

Seedling Care

• Immediately place under 40-watt shop lights, 8 inches above seedlings.
• Provide 12–14 hours of light daily.
• When 2–3 inches tall, transplant to individual pots.
• Harden off after last frost; plant in full sun, well-drained soil.

Jacaranda is frost-tender (Zone 9b+); in most of the U.S. it must be container-grown and protected in winter.
