Cananga odorata, commonly known as ylang-ylang, is a tropical evergreen tree native to Southeast Asia renowned for its intensely fragrant star-shaped flowers used in perfumery and aromatherapy. Seeds have erratic germination when fresh, but warm water treatment and patience significantly improve success; germination typically requires 2-8 weeks but may extend to 4 months. The tree produces essential oils valuable for luxury perfumes and requires warm, humid conditions to thrive.
Before sowing
Hot water or warm water immersion for 12-24 hours significantly improves germination success. Fresh seeds germinate erratically, but 6-12 month old seeds have higher germination rates.
Sowing
What to expect
Tips
Maintain consistently warm temperatures of 25-27°C (use heating mat if necessary). Keep substrate consistently moist but never waterlogged; use misting or bottom watering. Provide bright, indirect light; avoid harsh direct sunlight. Maintain high humidity (70-90%) using clear plastic covering or propagator dome with daily air exchange to prevent fungal growth. Older seeds (6-12 months) germinate better than fresh seeds. Ensure well-draining substrate to prevent root rot. Do not press seeds deeply; sow on surface or cover minimally with vermiculite or sand. Be patient—some seeds may take 3-4 months to germinate.
