I have known Colchicum seeds from my own plants germinate the Spring
following sowing. I rarely rush to collect it and so it does have time to
mature naturally which seems sensible to me - I find it at repotting time.
I do however agree that fast germination is the exception rather than the
I have never bothered to wash Colchicum seeds, though I have done this
with  Cyclamen. Colchicums do seem to germinate best after cold winters but
I have known it after warmer ones.  I subscribe to the theory that many
hard seeds are best sown and imbibed in warm conditions before Winter.
In flower here are Colchicums jolante from seed, munzurense and hirsutum.
