NOTE: the height rating here is way off. It can grow to 4' or 6' if that is how high it's supporting structure might be, but regularly climbs over 20' up trees and occasionally twice that in favorable conditions.

I've seen two really big vines at Jenkins Arboretum near Berwyn, PA in se PA, climbing way up large trees in the woods. This species gets huge; over 50 feet long. It does not really harm trees and needs some kind of structure to climb. Pretty plant with shiny dark leaves and white flower clusters. Native to the South of the U.S.

I have had this plant growing up a wall for about five years now and this year it finally bloomed. The leaves are elegant and the vine climbs demurely and slowly; it is not at all invasive. All in all it makes a nice, dense covering for any wall you might have. I grow it in full sun.

A beautiful native vine, it often is found climbing up deciduous trees or sprawling on the ground, although it must grow vertically to flower.

Ultimate height is 20-30 feet, although some vines have reached 40 feet.
