[pbs] Timing of Bloom in Bulbs

Of course there are "triggers" that awaken dormant bulbs - rain at the 
end of a dry season, warmth at the end of a cold one.

I'm still puzzled as to why some crocus flower in fall when many of them 
bloom in spring. And what advantage does colchicum gain, flowering in 
fall and waiting 8 months to produce seed.

And then there are bulbs that flower in summer, adding a third season 
into the equation . . .

fringe of white roots at the basal plate.
