This is a pretty, lightweight climber, sometimes known as coral vine, that blooms from late summer into autumn. Growing from tuberous roots, it scrambles over fences, pergolas or trees and produces long panicles of bright pink flowers above its heart-shaped leaves. It comes from Mexico and belongs to the small Polygonaceae family of plants, which also includes the genus Persicaria, members of which grow well in our Sydney climate. It can reputedly scale heights of between 8 and 12 m, but I have not found it a nuisance and I cut back all the stems almost to the ground in late winter and allow it to regrow over the summer months. This way, old foliage doesn't build up and it is kept under reasonable control. The vine grows best in full sun. Once established, it seems to cope with drought conditions. It is frost tender but has survived the occasional frosts I have experienced in my garden over the years. Propagation is by seed or semi-hardwood cuttings taken in summer.
