The above propagation data sourced from Claude AI
Pre-treatment: Seeds are soaked in warm water for 2 hours and/or placed into a 5% bleach solution for 3 minutes. Non-viable seeds (floaters) are removed during water soak.
Establishment: Seeds are hand collected when seed capsules have fully matured, typically in late July. There are 3 subspecies found on Catalina Island: ssp. cyclostegia, intermedia, and macrostegia.
