On the leaf only the backside has fuzz, the backside should also be a lighter color than the top color of the leaf
I just went ahead and listed all the other characteristics that would make it a paper mulberry! Without any pictures of bark, bottom side of leaves, or roots, I am not sure either. The reason I said paper mulberry is in the picture the leaves have different lobes to none at all, and that is indicative of a paper mulberry. Have a peaceful safe weekend!
