Propagation & Germination

The above propagation data sourced from Claude AI

Pre-treatment: Extended cold, moist stratification is needed. Seeds were also soaked in distilled water for 24 hours, placed in clear plastic germination boxes on two layers of blotter paper, thoroughly moistened with distilled water, and placed in a germinator at 4°C in the dark for a 60-day prechill.

Establishment: Germination rates and times may vary. Some protocols suggest that seeds may require two winters to germinate. Seed collection varies, but generally occurs in late June or early July. Seeds are typically dark brown in color when ready for collection.
