Hi, I am hoping someone can help me identify this plant/vine which I suspect is an invasive species. It is growing alongside my mother's house. It has grown to about 8 feet in height in less than 2 months so I think that equals weed and not a good one. I am thinking possibly Dog Choking Vine from the leaves but it has tendrils. The water table is at 6 feet or so, so it has all the water it wants. Bridal wreath is in foreground. Please help.

Thanks to all who looked at plant. I emailed images to the Wisconsin DNR and they were able to help me. It is a common carrion flower (scientific name: Smilax lasioneura). :)
