I’m trying to figure out the identity of this tree. Its in the backyard of our new home. In the summer it had BIG leaves, maybe 8 inches long as I remember. In the fall, fruit (or nuts) with four wings. Now it is showing off with masses of pink bell-like blossoms. The bumble bees and hummingbirds flit in and out. Its a big tree, 40 or 50 feet tall.

Once I get a good look at the mature leaves, I hope I can follow through with the tree identification at Arborday. But if you know this tree, let me know!
