I was just researching for a tree in my front yard that is a very difficult to plant location. It was a staging area when this community was built -- nearly 30 years now, but it still has super compacted clay soil under the thin loam of the lawn, plus less than ideal grading brings a lot of rain water to that spot.
I was looking at descriptions for Blackgum and thought.... Wait, didn't somebody say those shrubby things might be Blackgum?
Sorry -- I didn't realize I failed to thank you for the possible ID.
I must have taken photos of their fall foliage. I'll have to go look for them.
