    Yellow Passionflower is a climbing or trailing vine to 15 feet and is widespread in thickets throughout the eastern US. It has small, intricately detailed pale yellow-green flowers in summer followed by small black berries. Not particularly showy but good in its own right, especially at the edge of woods.
