Stemless and tuberous. Semi dry heavily wooded area. 50ft elevation and 75-150yds to nearest water body. Suggestion was giving lionsfoot rattlesnake root, but the glaucus patterning and lack of deep lobing on small-medium foliage does not seem to match. And yes, I did dig one up, but only because it started to come up when I removed some honeysuckle from around the patch so please do not come for me :)
Ugh if actually Japanese honeysuckle. Lots of it in the forest behind our development.
