Germination Information
Pre-treatment: Seeds are surface sterilized with a 5 to 10 minute Physan disinfectant soak or a 3 to 5 minute 5% bleach solution. They are then soaked in distilled water for 24 hours, followed by a 30 minute hot water soak or a 1:2 (v:v) liquid smoke to water soak for 24 hours. Seeds undergo natural cold, moist stratification during early winter months.
Establishment: Seeds are hand collected when fully matured, typically from December to May. Seeds are shiny black at maturity. Catalina Crossosoma is found throughout southern California and the Channel islands.
