Its a cherry. Its starting to lose leaves and will be bare almost 3 months before the others drop. Of course it comes back while the others are sleeping. It will just look like a dead tree going into the end of summer as usual.
Autumn it turns out, has some thing of a negotiable start. It by no means loses everything quickly like so many around here will, but it just peppers the lawn with leaves over the weeks. I have never had a "pile" of cherry leaves the way I get piles of oak and other leaves. I suppose I should find out which type of cherry it might be. Its a big sucker, the trunk diameter is kind of amazing.
