This kind of "sawtoothed" edged 3 leaf vine is growing near my trellis where I planted Mrs. Bateman Clematis last year. at first i thought it was my clematis, but then the clematis recently came up and put on its first leaves on a separate vine on the trellis. And it's not my Chinese indigo either. The indigo is the plant in the picture with the smooth edged oval leaves.
I don't recall planting anything else there besides the indigo and Mrs Bateman clematis, but it's possible. But it's more likely something "wild"
Should i "Leaves of 3 beware of me So get rid of me" or should i see what it does? It looks like it's a vine but I'm not really sure yet.
In the third pic if you go from the top of the pic to the bottom, you can see Mrs Bateman's leaves at the top on the trellis, then the plant in question in the middle in front of the trellis then the Chinese indigo at the bottom
