These velvety, dahlia-like, chocolate-maroon flowers have a delicious aroma, reminiscent of the best Belgian chocolates. One of our recommended plants, they’re particularly suitable for a sunny, exotic garden or a planting scheme based on ‘hot’ colours.
- Garden care: In autumn after the foliage has died back, reduce the stems to within 5cm (2in) of the roots. Lay in a tray of soil or compost and over-winter in a frost-free environment until early spring.
