Description and Growing Information
| Cultivation | Grow in a frost-free environment on a sunny patio. Otherwise it may be grown as a potted patio plant and brought into a cool greenhouse in autumn. It will benefit from an annual pruning especially if it is grown as a patio pot; prune hard in autumn before bringing into a cool greenhouse, let dry out between waterings. Prune again in the spring and fertilize throughout the season using a dilute water soluble fertilizer. |
| Pests | Whitefly may be a problem on greenhouse grown plants. Lack of water will cause premature leaf-drop receded by rapidly yellowing leaves. |
| Flower Description | Flowers are 2.5 cm wide and are purple in colour with a yellow centre. They are produced in profusion throughout the summer. |
