 You have touched on a favorite topic of mine, what triggers a bulb to 
put forth a flower at a specific time of year.

Is it the availability of water as in spring rains, drop in temperature 
as you have mentioned for lycoris or changes in light intensity or 
duration.  I have some cyclamen hederifolium flowering that have been 
sitting out side on a stone wall.  I put my boophone disticha in the 
basement under lights for the winter  and with out changes in water, 
light duration it almost always comes into growth in early March.

I imagine there are chemical triggers that are in place that are 
responsible for the flower initiation.

Any thoughts out there?
