Germination Information
Pre-treatment: Seeds require cold, moist stratification for 60-90 days. Imbibing seeds in water for 1 hour prior to stratification may improve results. Light treatment during stratification may increase germination rates.
Establishment: Germination rates vary significantly based on stratification and light conditions. Seeds are very small and collected when capsules begin to split. They are stored in paper bags or envelopes at room temperature until cleaned.
