Pre-treatment: Seeds are placed in fine mesh bags, soaked for 10 seconds in water at 95 °C, then immediately placed in cold water. Seeds are then placed into a 1% hydrogen peroxide soak for 24 hours, rinsed, and placed in water for an additional 24 hours. Mesh bags are layered in peat in a covered container and placed in refrigeration at 1 to 3 °C for 60 days. Check seeds in peat weekly and treat with 1% hydrogen peroxide if mold is evident.
Establishment: Native to northern California and southern Oregon, where it grows in mountain forests and woodland on volcanic soils.
