I have two of these in my backyard. It’s actually me neighbors yard but it’s an area behind their fence that they left unkept that I have cleaned up. I am Wondering what these two trees are. They seem like the same tree. Berries and leaves look alike. The bark on the small multi trunked tree resembles that of a cherry? Let me know. Hoping they are native and serve some value to wildfire in Philadelphia zone 7a because they sure are ugly with bad growing habits.
