Colchicum germination

But now, I think you meant: as a result of some unknown environmental
trigger, many different Colchicum species germinate, no matter how
many years they've been buried in their seedpots.
Diane,
I find this with Trillium germination...... last year I had seed sown
2, 3, and 4 years before all germinate, or at least in sufficient
numbers to notice that there were lots of seedlings simultaneously in
lots of pots.
I have found that some Colchicum (rhodopaeum for example) have
germinated easily (or conditions were just right) while others just
sit and wait.
Cheers.
