Update: I feel confident enough with the suggestion of Sanicula (genus) that I'm willing to make a preliminary ID of Sanicula canadensis. The habitat matches well (mesic deciduous woodland). I'll look for flowers in late Spring and early summer for confirmation.
I am stumped. Our edible plants tour guide called this "wild chervil," but that's a common name for Anthriscus sylvestris, a carrot relative that's toxic (and LOOKS like a carrot relative). This one looks like Virginia Creeper and/or American Ginseng. I obscured the location just in case it IS American Ginseng, but I'd be surprised if it is.
We did eat leaves and they tasted like parsley.
Note: it looks like Virginia Creeper but doesn't have a trailing habit or spread much laterally. There are 2-3 levels of growth upward.
Sorry the pic is rather grainy. I've recently upgraded from this point-and-shoot to a really nice smartphone, so hopefully if I see this plant again I can get better photos.
The species in this area, according to BONAP, are canadensis, odorata and smallii.
Sanicula is a genus of plants in family Apiaceae (or Umbelliferae), the same family to which the carrot and parsnip belong. This genus has about 40 species worldwide, with 22 in North America. The common names usually include the label sanicle or black snakeroot.
