Germination Information
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 collected when the capsules begin to split in July. Capsules can be collected individually or the entire stalk cut. Seed is black in color. Seed is stored in paper bags or envelopes at room temperature until cleaned. Seedlings which germinated outside died when placed in the greenhouse.
