I *think* it's a native tree to Georgia Piedmont. It's growing at the edge of my property which borders a wetland. It seems to be growing upright, leaves are opposite with an odd leaflet. I cannot see any fruit yet as it is a young tree. Ash?
If you were to clip off a small branch or twig, and take it to where you could shoot some in-focus closeups of the stem where the leaves attach, we could tell you right now whether it is a White Ash (Fraxinus americana) or Green Ash (Fraxinus pennsylvanica). The leaf scars can (and usually are) a definitive difference between these two common Ash species.
Fall color is not the best determinant of species identification. Just google some cultivars of these two, and see the wide range of colors that have been selected for.
