Propagation & Germination

Stratification:
Warm then cold/moist stratification (double dormancy) — 150–240 days
Germination Time:
365–730 days
Notes:
Double dormancy requiring warm then cold stratification. Seeds may take 2+ years to germinate; hypogeal germination produces root first, leaf emerges following year.

The above propagation data sourced from Claude AI

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. Expose to fluctuation outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in the spring. * seeds must be stored cold and moist; germination is unlikely after storage >6 months; if seeds are received dry, try hydrating in damp paper towel @ 20°C for 1 week; 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
