Dalbergia nigra, commonly known as Brazilian Rosewood, is an endangered tree species endemic to Brazil's Atlantic Forest, valued for its dense, rose-scented hardwood used in musical instruments and fine furniture. Fresh seeds germinate readily within 10-20 days at temperatures between 25-30°C with germination rates exceeding 80%. Stored seeds require pre-treatment with hot water soaking and scarification to overcome dormancy and improve germination success.
Before sowing
Fresh seeds sown directly germinate best; stored seeds benefit from scarification and soaking
Sowing
What to expect
Tips
Use fresh, mature seeds whenever possible for best results. For stored seeds, scarify by soaking in hot water (nearly boiling) for 24 hours, then soak in warm water for 12-24 hours before planting. Vermiculite substrate reduces germination time compared to other substrates. Maintain consistent moisture without waterlogging. Seedlings develop slowly and require 6-7 months to reach transplant size. Ensure seeds come from legal, sustainable sources as this species is CITES Appendix I protected. Light treatment with indirect sunlight promotes germination.
