Porcelain berry or wild grape? #815963
Asked November 06, 2022, 11:56 AM EST
I found this plant growing in a shady spot behind some azaleas. iNaturalist isn’t certain whether it’s native grape or porcelainberry. It doesn’t seem particularly glossy like porcelain berry, but could that be because it’s still quite young? I’d appreciate your thoughts on ID.

It is difficult to accurately identify plants this young, even in person.
We can't reliably say for sure but this page from
Plant Invaders of Mid-Atlantic Natural Areas can tell you more of what to look for if you decide to let it grow a bit:
https://www.invasive.org/alien/pubs/midatlantic/ambr.htm, for instance, young twigs are usually pubescent (hairy), and stem pith (the interior when sliced/broken) is white, while grape is tan or brown.
As you likely know, porcelainberry is an non-native invasive vine that should be removed. Here is our page on it:
