My roommate and I were wondering about that one too. I used to live in Wenatchee, WA, which considers itself the apple capital of the world. Looking around the city at all of the orchards I can see why.

So anyway, they talked about the total temperature over time to allow the trees to blossom, so I thought that it might be because some trees had their start in a green house, where the temperature was a bit hotter, so they have a prediliction to bloom a bit earlier than others.

Don't know...
