Germination Tips


Sow immediately. 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.


This species needs special care as described.


Give sown seeds several weeks @ 20°C to imbibe water (perhaps even germinate!), then expose to fluctuating outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in spring. See

Special Care: 
week; first need 20°C during which a radicle is formed, then cold (4C) for at least 86 days to trigger emergence of cotyledon which will appear when temperature increases in spring (no further leaves are formed that year); if sown early enough, cotyledon will emerge next spring but usually not until second spring; keep seeds in pots for 2 years
Most of the seeds in our Germination Guide have been offered from time to time in our annual Seed Exchange (Seedex).
