How do tulips know when to bloom?

"Googling", I found the National Gardening Association's website. www.garden.org


For tulips to bloom, they must experience a 6-10 week period of chilling/cold weather before the warmth of spring causes them to grow and bloom. (When they bloom is dependent on geographic location and weather conditions.)


Searching through our school library, I was unable to locate any print materials that answered this question about tulips.


Searching Credo Reference online, I couldn't find the information I was looking for. I think it was a problem with not knowing what to use as search terms. (Anyone have any suggestions?)
