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 https://www.youtube.com/watch?v=SO_KKbGYTEM

Special Care: 
germination unlikely after dry storage > 6 months. Gabriela Costea notes that fresh or moist packed seeds seeds can have two types of morphophysiological dormancy (after Baskin & Baskin): In the first case the roots will emerge in late fall after a warm stratification and the shoots growth will begin in the following spring (= after cold stratification); deep simple epicotyl dormancy. In the second case (said to occur (said to occur in about 49% of seeds according to a study), the shoots growth will begin in the second spring after sowing; deep simple double dormancy. It is well known that the germination dormancy traits have a genetic component.
Most of the seeds in our Germination Guide have been offered from time to time in our annual Seed Exchange (Seedex).
