This vine blooms on and off all year more in milder weather with frilly clusters of snowy white heart-shaped flowers. At first glance, it appears that each little blossom is tipped with a touch of scarlet. The white part is actually a flower "bract" from which a red flower emerges. Leaves are a soft dark green and contrast beautifully against the white. The foliage tends to stay darker, fuller and more lush in part shade. In full sun the leaf color fades to a medium green and growth is less dense, though you'll get more profuse flowering.
