C. x durandii reaches 3 to 6 feet tall and blooms all summer. It is considered a nonclinger or nonclimber (unless its vines are tied to a trellis or other structure) due to the fact that its vines aren't strong enough to grow up. They tend to fall over, giving it a form more like a bush. It's great for growing in a container or being allowed to meander among small shrubs. For heaviest flowering, prune back to 12 inches from the ground in early spring. (Pruning Group 3.) Zones 5-9.
