We have the same tree, on a heavily wooded lot, that I started to clear a little last year when we moved to the Midwest.
The plant is very durable, the deer dined a bit over the winter, and yet it came back this spring and summer without missing a beat. I wish I had more of these on my property, as they are disease resistant and healthy year round.
Wish I could tell you what it is, but I would like to have a few more around.
