I am helping a friend redo their yard, and we are finding all sorts of leftovers from previous owners. One of them, this vine, seems to be a deliberate introduction, but I haven't been able to identify it yet. It's vine is very similar to honeysuckle in diameter and behavior, (twining, with no tendrils or suckers), and it's leaf looks like this. We are in the extreme northern tip of Kentucky. and it did overwinter. Thanks for the help!
