The above propagation data sourced from Claude AI
Pre-treatment: Cool, moist stratification and cool growing conditions. High germination was obtained from seeds sown in flats and left outside under cool, fluctuating spring temperatures.
Establishment: Seeds are black when mature. They are stored in envelopes or paper bags at room temperature until cleaned. Seedlings which germinated outside died when placed in the greenhouse.
