Colchicum germination

Jane,
I have just read your comment again and understand it differently the
second time.
I assumed you meant that when seeds of a certain Colchicum species
germinate, they all do.
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.
If the precipitating factors occur this year, then species A may
germinate in only two years, but if the constellation of events don't
occur for another ten years, then maybe species A might take 12 years
to germinate this time, but not every time.
Am I right in my second interpretation?

years
old the seed pots are. Apparently there is some environmental
trigger that
affects many species similarly.
