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.
