Allium karataviense ssp. henrikii

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.

H

Use repeated cycles of 4°C, then 20°C for 3 months each. Germination is very prolonged.
Special Care: 
store seed @ 4°C; seed stored @ 20°C takes 6-9 months to germinate
