Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 150–270 days
- Germination Time:
- 365–730 days
- Notes:
- Double dormancy requiring warm period followed by cold stratification. Seeds may take 2+ years to germinate and additional years to reach flowering size.

Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Cold-moist stratification for 60 days.

ORGHPS Germination Guide: Sow immediately, Either the viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience. Use repeated cycles of 20°C, then 4°C for 3 months each. Germination is very prolonged. Requires darkness. * hydrophilic; seeds must be stored cold and moist; during 3 months @ 20° a radicle is formed; then 4°C for at least 86 days will trigger emergence of a cotyledon which will appear as the temperature increases in spring; no more leaves are formed that year; if sown early enough, a cotyledon may emerge first spring but usually not until second spring; keep seeds in pots for 2 years
