Parthenocissus quinquefolia or Parthenocissus vitacea?
This "quinquefolitate" vine is growing on the deck leading to the garden with the Siberian Iris called Snow Queen (unfortunately not yet blooming). The woods are full of this woody vine that climbs quickly to the top of the tallest trees. Tarzan would be quite satisfied with it!
