Please help me identify a tree in the northern Virginia/DC area. Picture taken today May 8, 2007 thanks, Bob
I'll be interested to see what other people say, but since you are in my neck of the woods, I've got to take a stab at it. It looks like the tree has palmate compound leaves, which to me says "horse-chestnut." Looking around for pink-flowered horse-chestnuts, I found Aesculus carnea.
Another vote for Aesculus × carnea. It is a hybrid between Aesculus hippocastanum and Aesculus pavia.
