Trillium albidum

Germination Tips


This species needs special care as described.


Requires darkness.


Use repeated cycles of 20°C, then 4°C for 3 months each. Germination is very prolonged.
Special Care: 
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
Most of the seeds in our Germination Guide have been offered from time to time in our annual Seed Exchange (Seedex).
