Adonis vernalis

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: 
hydrophilic, sow as soon as seed is ripe; ; will not germinate if seed has dried; if stored, must be put in plastic bag with barely damp vermiculite; keep them warm during summer, coolish towards the fall and then 4⁰C at the onset of winter. Do not store them in the freezer because the formation of ice crystals will damage cell membranes; much chaff and nonviable seed is typical; does not need chilling if seed is fresh
Most of the seeds in our Germination Guide have been offered from time to time in our annual Seed Exchange (Seedex).
