The chocolate vine is an unusual climber, that can suffer damage from late frosts. The maroon-chocolate flowers look almost artificial, with waxy ‘petals’ forming an inverted cup shape. These are clustered along the stems and have an exotic spicy fragrance with a hint of vanilla. They stand out against a background of light purple, three-lobed leaves, most colourful in full sun. In mild conditions the leaves last all winter but in cold areas expect them to be shed. After a particularly warm summer, large sausage-shaped fruit dangle from the stems.
