mystery tree– ID please?

I never saw these before but the mature trees are lovely, they are not tgoo tall, oval in shape and flower a very pale green, I believe this is a baby one but what is it? http://i39.photobucket.com/albums/e166/paleriter/mystery-tree3.jpg it looks like it could be messy after blooming, is it a well-behaved tree? TIA.
