The delicate beauty of bleeding heart vine belies its fast growth habit. It’s one of the best fast growing vines for covering an arbor, pergola or chain link fence. 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.
