which native clematis is this?

I think this is a native clematis, but I'm not sure which. Growing in central MS, in mostly sun, well drained sandy loam soil. My best guess is C. dioscoreifolia.

It's a beauty, regardless!

Probably Clematis terniflora, since the leaf margins aren't cleft.

Hmm, apparently Clematis dioscoreifolia is now a synonym for Clematis terniflora and is not considered native.

I am also looking to identify a very similar clematis (and am hoping it is native ....).

Oh, heartbreak! I did not realize that C. dioscoreifolia is a synonym for C. terniflora, and that it is not native. How very disappointing, especially since this plant was found in the woods on public land and not in someone's yard. That means it's spreading and someone didn't plant it there :(

Let us know about your Clematis sp. please, esh_ga. Curious minds want to know.

Mine was confirmed as C. terniflora too (by the guy that gave it to me). So mine will be ripped out after flowering. But at least it will be a hole that is ready to be filled with something else!

C. terniflora/dioscorefolia (used to be C. paniculata and a few other various species) is a known invasive across much of the country. We've had numerous discussions about it on the Clematis forum. It is a prolific seed producer and the seeds are easily dispersed via fluffy appendages.

Oddly, the seeds do not have sufficient time or warmth to ripen properly in my area so this is not an invasive species in the PNW.
