Canna (or canna lily) is not a true lily. Although a plant of the tropics, it is easy to grow in most countries of the world as long as they receive at least 6–8 hours average sunlight during the summer, and are moved to a warm location for the winter.
The plants are large tropical and subtropical perennial herbs with a rhizomatous rootstock. The broad, flat, alternate leaves that are such a feature of this plant, grow out of a stem in a long, narrow roll and then unfurl. The leaves are typically solid green and the flowers are red. Cannas grow best in full sun with moderate water in well-drained rich or sandy soil. In arid regions, cannas are often grown in the water garden, with the lower inch of pot submerged. Plant is sensitive to frost and will rot if left unprotected in freezing conditions. Suitable for containers, otherwise zone 8b+
