Red mullberry?
I love big trees. But that was the first big thing I had done after I bought the house. Had thered mulberry cut down. Couldn't keep it off the house. I'd have to trim it several times each year. Tough wood. resists rot.
Also had the chinese paper mulberries in the back neighbor's yard cut down. They're one of the worst weed trees around here.
I don’t know. The berries are near black and quite tasty. If you can get them before a flock of birds gets to them. Roots or not, i wouldn't want them anywhere near the house or cars
