Cannas are easily grown tender perennials with architectural foliage and brash flowers that inject a dash of exotica. They can be grown in shape and colour to the end of the summer season.
The most popular kinds of canna tend to have gladiolus-like flowers perched high above the large, paddle-like leaves. In addition to those listed below, keep an eye out for new hybrids that keep coming on the market. Cannas generally grow 1.5m to 2m (5ft to 6ft) high, with a spread of nearly 60cm (2ft).
Canna watering
These can be grown as marginal aquatics in plastic baskets around the edges of a pond. In the west of England they often survive in ponds all year, but in colder parts of Britain they need to be removed in winter and protected from frost, as with border cannas.
