Germination Information
Pre-treatment: Seeds are removed from storage and placed in water at room temperature for 12 - 18 hours, then placed in self-sealing, polyethylene baggies and placed in refrigerated conditions (2 to 4°C) for 28 days to satisfy stratification requirements.
Establishment: Entire cones are harvested by hand from trees when they begin to turn tan or brown, prior to scale opening. This typically occurs in early to mid-September within its natural range and slightly later when grown at lower elevations. The species is found from Idaho and Oregon south through California and in the southern Rocky mountains in New Mexico and Southern Colorado.
