Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 14–45 days
- Notes:
- Seeds require light for germination and perform best with cold-moist stratification followed by cool temperatures.
Pre-treatment: Seeds undergo a 5-6 month cold, moist stratification either in a refrigerator maintained at 34 to 37°F or outdoors. Seeds are then sown in conetainers or on germination pads in petri dishes.
Establishment: Germination rates decrease with decreasing light intensities. Seedling mortality was 0% at all irradiance levels. Seeds are collected in late August to the end of September.
