Pre-treatment: 5 month outdoor stratification. Germination did not occur until the second spring; 1.5 years after sowing. Germination occurred under fluctuating spring temperatures.
Establishment: Seeds are collected in paper bags and kept in a well ventilated drying shed prior to cleaning. Collect mature capsules when they begin to split and turn tan in color in July and August. Seeds are brown at maturity.
