Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 90–120 days

The above propagation data sourced from Claude AI
Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Cold-moist stratification for 60 days.
Notes: Seeds may require light for optimal germination.
