I do agree with your point about the lawns. I was looking for this thread to post pictures of my trees. But, the HOAs in Ga love Bermuda, which cost a small fortune to grow.
I believe that Ga banned the Bradford pear, or at least discouraged planting them, with the kudzu (They did ban planting Kudzu, it's a real problem). Builders used to love the Pear trees, you don't see any builders planting them now.
Yes, they are everywhere because they grow so easy, they are weak trees and split with a good wind and their flowers stink.
I checked and the Tulip Poplar is native to Georgia. I guess I should have said that it just started growing in the yard and wasn't a purchased tree.
