Propagation & Germination
- Stratification:

- Germination Time:
- 14–30 days
- Notes:
- Seeds benefit from cold stratification for 4-8 weeks; sow in fall or after cold treatment.
Pre-treatment: 6 prechilling treatments were used: 0,2,4,8,12,16 and 24 weeks of moist chilling at 2C in the dark.
Establishment: E. corymbosum flowers in late summer to fall and seeds ripen in late September to early November, depending on elevation. The germination response is likely related to habitat temperature, with seeds from warmer, lower elevation sites germinating faster than those from cooler, higher elevation sites.
