Some fall bulbs seem to respond to water and some to lower soil 
temperature. The earliest Colchicum to flower here is usually C. alpinum, 
which is as the name implies a plant of higher elevations, where it would 
have to bloom earlier to go through its reproductive cycle. I think that 
Colchicums are more likely to respond to moisture -- they often bloom in 
their shipping bags, where moisture is retained but where one supposes they 
are fairly warm.
