The above propagation data sourced from Claude AI

Pre-treatment: Seeds are placed into fine mesh bags and soaked in a 1% hydrogen peroxide (3:1 water/3% hydrogen peroxide) for 24 hours, then rinsed and placed in water for an additional 48 hours. Seeds are then layered in peat and placed into cold stratification (1 to 3 °C) for 90 days. Seeds should be checked weekly and if mold is evident, they should be treated with 1% hydrogen peroxide.

Establishment: Seeds are collected between May 7th and July 29th. The plant is found in canyons below 5,000 feet elevation, in the coastal and foothills of the Sierras; from Santa Barbara to Del Norte County and Tulare to Shasta County, California. There is a discrepancy in the length of the establishment phase between protocols, with one suggesting 3 to 4 weeks and the other suggesting 8 days.
