Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 14–30 days
- Notes:
- Seeds benefit from cold moist stratification for 30-60 days to break dormancy.
Pre-treatment: Seeds placed in 32-34°F for a 10-day cold stratification treatment and then exposed to 72-77°F. Alternatively, seeds can be subjected to six temperature treatments intended to represent different seed sowing times and locations in the Colorado Plateau.
Establishment: Elymus elymoides is a widespread North american species found in dry soil and roadshoulders in prairies and open forests. Propagation collection varies from wildland collection to hand collection into paper yard bags to purchased seeds. Germination rates and times may vary based on pre-treatment and establishment protocols.
