I think this is American Ginseng, but it appears to have 7 leaves instead of the usual 5 on each prong. Any ideas?
Could still be: American Ginseng (Panax quinquefolius): recovery strategy 2018 - Canada.ca Although, hmm... that might be describing the actual number of leaves and not leaflets. Still, most plants with compound leaves can rarely have amounts of leaflets that are lower or exceed the standard amount.
