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 or more years to germinate. Elaiosome attracts ants for dispersal.

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. * 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
