I just received several packets of Allium seed from one of the exchanges and I am seeking seed germination advice. My main question is do these require cold, cool, warm or fluctuating outdoor conditions to germinate? or an i grow in pots in a cool 55F basement?
Allium beesianum hopefully- China, blooms in August
Allium callimishon- Crete, blooms in fall
Allium platycaule- western American sounds like cold is needed
Allium victoralis- bloom in June
Thank you
