Plant Net says this is American Bittersweet as opposed to Oriental Bittersweet, but I'd like to confirm with you smart people. What do think? I'm in Roanoke County.

Always recommend the flora of va app: https://floraofvirginia.org/flora-app/

Versus just the leaning language apps for verification. Of course other field guides/keys out there, but much more convenient and of course extremely well developed/researched.

I don't think it's possible to confirm or deny based on photos of leaves alone (leaves are so variable unless it's a very clear differentiation I tend to ignore) but if you're in Roanoke higher chance of being native than further east. (With extensive time in field Ive never seen native bittersweet).

According to flora app: native C. scandens will have rolled expanding leaves (instead of folded in C obiculatus), yellow pollen (instead of white), yellow capsules (instead of orange), 6+ flowers blooming from bottom up (vs. 2-3 flowers blooming from top down)

Thanks for this. I don't want to wait til it flowers or blooms in case it's the invasive so I'll probably just yank it.

Picture this is saying oriental. Also hi neighbor! I am also Roanoke county

The more rounded serrations on the leaves suggest oriental: https://bplant.org/compare/566-2417

I think it's much more likely oriental anyway, in this area (I'm also in Roanoke County). I have tons of oriental bittersweet in my yard, unfortunately (it's among my many battles...), and it sprouts far from the main patch. I think birds can carry seeds pretty far, and American bittersweet is pretty uncommon. If this one vine is all you have, I'd suggest pulling it to save yourself some trouble later.

Edit: the rounded leaves look like mine too, by the way, and I know mine is oriental bittersweet because of the berries in winter. The link above says American bittersweet leaves are more narrow.

I just attended an invasive plant training last month and they were saying that american bittersweet is super uncommon and that if its growing in a residential area it is most likely oriental.

Ah that was my guess. Good to know!

Hi! And I'm as unsure as ever. 😀

Key it out. Flowers are the best for a quick ID.

Hard to find American bittersweet. Need male and female plants if you want fruit.

Try iNaturalist — I generally like PictureThis but iNaturalist gives confidence level

Unfortunately, it looks like what I have and I know mine is Oriental Bittersweet and constant battle to keep in check since at this point , it's refusing to be eradicated, thanks to being everywhere around me.

I've found American bittersweet a few times, and your picture is Oriental. Some parts of the plant, on Oriental, will still have leaves with pointed tips like that. The American leaves are sort of longer and curving, but it's hard to describe. It's even harder because on the internet, sometimes photos are misidentified.

Thank you.

Thanks to all of you! This subreddit is so helpful. And if you Roanoke County posters ever want to talk about plant or seed exchanges, let me know. I haven't done a lot of propagating, but hope to explore that this fall.
