Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 90–120 days
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 30–90 days
- Notes:
- Requires warm stratification followed by cold stratification. Scarification improves germination rates.
