I found this thread on the U of MN site and thought you might find it informative....Helen.

Here is a link that might be useful: Invasiveness of Virginia Creeper

I'm in zone 3 and don't find it to be "invasive" at all. We live in quite a wooded area and it is "native" here. I let some of it grow where it likes, others I just pull or chop down. This year I have had only two come up in any of my flower gardens and these were quickly eliminated. They do die bck in the winter and seem to like quite abit of sun, so I'm not sure if your chosen spot will have enough sun. I'm surprised that the Nurseries are selling it as Englemen's ivy. Most anything to make money.
Good luck !

I have quite a lot of VC in my woods, but not to the point of strangling anything or being invasive. The wild grape is much more agressive and harder to control IMHO. If you want more, I'd suggest you air layer the plant you have as it will root at nodes if they come into contact with the ground.

It will not be as agressive in the shade, but you should keep an eye on it so as not to injure your smaller tree. I've never seen it do much to a large tree except grow up the trunk. In full shade the fall color is not as vivid, but I still like it.

First year you'll have to water as other new plants to get established, then it will pretty much fend for itself.
