rampant, woody vine growing to 30 ft (9 m) or more and requiring
plenty of space and a sturdy support.

purplish stripe down the center of each petal.
It tolerates wind, dry conditions and salt spray, so it is an
excellent plant for seaside gardens.

water freely during the growing season. Thin out crowded stems after
Propagate from cuttings.
