Germination Information
Pre-treatment: Seeds are placed in fine mesh bags into a 1% hydrogen peroxide (3:1 water/3% hydrogen peroxide) soak for 24 hours, rinsed, and placed in water for an additional 24 hours. The bags are then placed in sealed containers in refrigeration at 1 to 3 °C for 90 days. Seeds should be checked weekly and treated with 1% hydrogen peroxide if mold is evident.
Establishment: Seeds ripen in late summer to early fall (August/September). The plant grows mostly in relatively dry climates in Chaparral and woodlands in part shade or shade and at low to mid elevation. It can grow in sandy, loamy, or clay soils as long as they are moist and well-drained. Found in the west coast of the US from California up to southern and western Washington.
