Looks to be Clematis virginiana, so a native (and therefore not invasive) species. But it does grow quite aggressively throughout much of its native range, which is pretty much anywhere east of the Rockies.

You got it. I guess technically you're right, but the stuff sure has invaded areas of my lot and also the adjacent field since I don't remember seeing it at all when I first moved here.

It is a thug at the local golf course where it is covering huge swaths of the roughs. It came up by my fence but was far too aggressive for me to keep.

I’ve grown it from seed and am on my fourth year waiting for it to even get 1 foot long. Go figure!
