Propagation & Germination
- Stratification:
- Cold/moist stratification required — 14–30 days
- Scarification:
- Seed coat scarification required before sowing
- Germination Time:
- 14–60 days
- Notes:
- Scarification of hard seed coat improves germination. Cold stratification beneficial but not always required.
The above propagation data sourced from Claude AI
Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Scarify, then cold-moist stratify for 60 days.
Notes: Seeds may require light for optimal germination.
