The above propagation data sourced from Claude AI

Pre-treatment: Seeds require a 30 to 90 day cold, moist stratification. They are placed in fine mesh bags and buried in moist peat moss in ventilated containers under refrigeration at 1 to 3C.

Establishment: Seeds are collected in late August when capsules turn brown and begin to dehisce. They are brown at maturity and are collected in paper bags and kept in a well ventilated drying shed prior to cleaning.
