Thanks, everyone! This plant has been a mystery to me since we moved to this spot 4 years ago. It appears to love this side of the mountain (east side) and is growing in 3 ft diameter clumps with a very prolific show of flowers. Quite the display for spring! I just wish it would last a bit longer in the season. Cindy

Great, invasive. Fits right in with the Japanese honeysuckle and knotweed and bindweed. Only thing I haven't found yet is garlic mustard, but no doubt it is there somewhere. And I'm the one who wouldn't let the builder bulldoze that area - I wanted my "woods"!!!

Just a guess, but perhaps Leatherwood, Dirca palustris. One identifying feature to check is whether the lateral buds are hidden by the leaf petiole.

Gracie, looks like a match! Thank you ! Oh, I'm driving out to Possibility Place today lol. I love those leaves.
