canna lily 'Tropicanna'
Canna ‘Tropicanna’ has become one of the most popular cannas grown worldwide and quite understandably.
Most growers agree that it is a tall, undemanding, robust cultivar with strikingly marked, almost psychedelic foliage topped by huge orange flowers. Given a rich diet and plenty of water in the growing season and protection from winter frost, it is a high octane ‘must have’ splash of colour for any tropical border.

Care & Size Guidance
The foliage of ‘Tropicanna’ will reach a height of about 60cm+ but including the flower spikes attain a total of 1.2m. A showy statement feature for a sunny spot, they do best in rich fertile soil or with regular feeding.
They are very sensitive to winter frost: In mild areas they can be left outside in a sunny sheltered position if soil is not too wet and a deep layer of mulch applied. In colder areas they should be lifted after the first Autumn frost, cut back and stored in barely-damp compost in a frost free place for the winter.
