Propagation & Germination
- Stratification:

- Notes:
- Seeds require light for germination and benefit from cold-moist stratification to break dormancy.
Pre-treatment: Seeds require 6 weeks of cool/moist stratification at 38F or a 5 month outdoor cold, moist stratification when fall sown.
Establishment: Collect mature inflorescences when perigynia and scales turn dark brown. Seeds are collected in late August to mid September and are kept in paper bags in a drying shed prior to cleaning. Germination rates were reported to be low even with pre-treatment.
