Often grown for their dramatic foliage - large banana like leaves - Cannas provide a strong ornamental interest and immediately give a touch of the tropics in the garden. Ranging from 2-8 ft. tall (60- 240 cm), they bloom from mid summer to fall in a warm array of colors varying from red, orange, yellow to pink or cream.
- Flowers last only a day or two, but are generally quickly replaced.
- The foliage of large paddle-shaped leaves may be striped or variegated and exists in shades of green or bronze.
- Perform best in full sun in organically rich, moist and well-drained soils.
- Canna Lilies look at their best when massed along walls or hedges or in garden beds where they proudly stand out. Spectacular on a patio, they are well suited to container growing.
- Very sensitive to frost, there are tender perennials that are only hardy to zones 8-11. Therefore, in cooler areas, their bulb will have to be dug up before the first frost and stored indoors over the winter in a dry place before being replanted in spring.
- Cannas are largely free of pests but in the USA, special care has to be provided to protect their leaves from the damage eventually caused by the Canna Leaf Roller.
- Deadhead Cannas throughout the growing season to keep them blooming for as long as possible.
