Propagation & Germination
- Stratification:

- Germination Time:
- 14–30 days
- Notes:
- Light enhances germination. Seeds are very small and should be surface-sown on sterile medium.
The above propagation data sourced from Claude AI
Pre-treatment: 6-month cold moist chilling in a refrigerator maintained at 34 to 37°F
Establishment: Germination does not decrease with decreasing light intensity from full to partial, but declines substantially from full and partial irradiance to zero. Seedling mortality is high in the partial and zero irradiance treatments.
