The above propagation data sourced from Claude AI
Pre-treatment: Seeds are soaked in water overnight, followed by a warm treatment at 75 degrees F, then cold stratified at 35 degrees F in peat for 90 days or until seeds start to germinate.
Establishment: Seeds are collected between June 20th and November 15th. Mature inflorescences and seeds are brown. The plant is found on coastal bluffs and flats, in largely Northern Coastal Scrub communities; from southern Washington to Monterey and Del Norte counties, California.
