This plant has been growing on our locust for about 20 years. I know it is invasive in some areas, but it is about 40 feet up the tree trunk and has not spread to other trees. I'm sure some birds may have carried seeds off, but I have not seen much of this in our area. I love the leaf against the texture of the locust trunk. I'm afraid I'll have to give it a positive as far as our experience goes.

Do NOT plant this invasive vine. My neighborhood in eastern Cincinnati is OVERRUN with it. When I bought this house, the yard (mostly shade) was completely taken over by wintercreeper, which marches over and through fences and scaled up shrubs and tall trees. Thick (3"-4" diameter) ropes of it girdled tree trunks. It was a nightmare to eradicate - took me two summers of backbreaking labor. Because my neighbors are careless and/or lazy, they allow this invader to take over everything in their yards, and the berries fall into my yard, which means I have to be ever-vigilant to pull up any seedlings. Woods and forests are being choked to death with it. Local nurseries actually sell the stuff. I think it should be banned from sale. It's the kudzu of the southern Midwest.
A horrible invasive weed here in Eastern Kansas and much of the rest of the Eastern USA. It's completely smothering some woodlands here and will climb up, over, and kill just about anything with time. It's very difficult to get rid of too, because small root fragments left after pulling will push up more foliage and it's very resistant to some common herbicides.
