Convolvulacae

An evergreen vine that seems to go on forever, with heart shaped leaves and trumpet-like purple/white flowers.
While it likes a hot climate, it seems to do best where there is some shade during the day.

As an active garden herb it is not one you would use often. The resin 'convolulin', is the active ingredient in the root, and is such a powerful cathartic that it should seriously not be used.

It is a delight, however, trailing over an old and dilapidated fence.
