Propagation & Germination
- Stratification:
- Cold/moist stratification required — 60–90 days
- Germination Time:
- 30–60 days
- Notes:
- Seeds benefit from cold stratification for 60-90 days to break dormancy.
Pre-treatment: Warm stratification for 6 to 17 months followed by cold stratification for 3 to 4 months. Gibberellic acid treatments can be used but results may be poor. Best results when seeds are planted soon after collection in the fall.
Establishment: Seeds often germinate prematurely during the stratification treatment period, which can lead to etiolated seedlings in the stratification containers. It is recommended to wait two years for the seedlings to germinate after planting the seeds.
