Not sure what this guy is , but it can grow quite tall...this one is only about 2-3 feet atm and is available for adoption if anyone wants
Acer campestre, in a bush form. Presumably it popped up there on its own (as a weed) and maybe got cut down once or twice. So would have to be re-trained in order to have a tree shape. Also should be dug up for transplanting in November and not this early, while still in leaf.
@War good evening, looks like Acer campestre or Field maple. Too far away for me Lol. But a kind offer.
