What is this plant?
-A: Paper Mulberry

This is the paper mulberry, but it is not related to the mulberry. These trees were brought to the U.S. as a shade tree and escaped captivity. They are invasive. They reproduce by seed and rhizome. You can use a herbicide on it, but it will be useful to try to dig up as much of the roots you can. The roots store carbohydrates that will allow the plant to send up new shoots from the roots.
