Can anyone out there in garden blogging land help me identify this please? This mystery vine is coming through my fence from the neighbor’s garden. It doesn’t appear to be poison ivy and that has been a nuisance in the past don’t get me wrong. I’ve been a bit leary about touching it nonetheless. Next time I see my neighbor I’ll mention it to him. I don’t want to bother him since one of my wandering vines has creeped into his garden too. 
‘Sweet Autumn’ Clematis or Clematis terniflora has jumped into the overgrown Nandinas and is blooming it’s heart out right now. He hasn’t complained or whacked it back this summer yet.
