Propagation & Germination
- Stratification:

- Germination Time:
- 14–30 days
- Notes:
- Seeds benefit from cold moist stratification for 60-90 days to break dormancy.
Pre-treatment: Seeds are sown into cone-tainers filled with Sunshine # 1, a soil-less peat-based media amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). A minimum of 30 day cold, moist stratification is also recommended.
Establishment: Seeds are collected in late August when perigynia turn tan and are easily stripped from the inflorescence. C. deweyana grows in moist forest openings and streambanks, from near sea level to near tree line, widespread throughout North America and eastern Asia.
