I was hiking around Mt. Rogers in VA earlier this month and I saw a lot of a plant that looks a lot like poison ivy but I don’t think actually is. I’ve attached three pictures to help: one wider shot of the whole plant and then two close-ups of a five-leaf tip and a three-leaf tip. The “leaves of three” groupings look like poison ivy to me, but they’re on the same plant a
s the groups of five, which I’ve never seen poison ivy do before. They aren’t two different plants, though; they’re both growing from the same main stem.
I was wearing shorts and had to go through one particularly overgrown area of trail. I tried to keep it off me best I could but ended up brushing up against quite a lot of it anyway but with no reaction. That’s another reason I don’t think it’s actually poison ivy. Does anyone have any idea what this plant is? Thanks.
