If you are looking for something different to add height and drama to a water feature, garden pond or even a container filled with water why not come to our plant sale at Open Gardens Constantia in November where we will have some of these plants on sale. They give a wonderful tropical look to the garden.
These aquatic, rhizomatous perennials are so easy to grow just needing to be planted in a wet, boggy position. They hold their large canna-like leaves at right angles to the stems during the day – but move then to an upright position in the evening. Bunches of violet blue flowers bow down the tall, 2m high flower stalks in summer. Need full sun. Their giant leaves turn gold in autumn and then die back for a short period over winter. Height 1. 5 -2 + m.
