Description

Canna hybrids are generally characterized as having bold foliage and large showy flowers that come in a variety of colors. They are cold hardy and heat-tolerant, making them a good selection in a variety of landscapes.

When selecting canna plants, please note that they have a history of viral infections. This is an issue monitored by the California Department of Agriculture and you should ask your nursery about this to make sure their stock does not carry the virus.

Equally effective in containers and in the ground. Most are hybrids descended from species native to the American tropics and subtropics.

All show well in groups against plain backgrounds. Grow in borders, near poolsides, in large pots or tubs on terrace or patio. Plant in full sun in a rich amended soil. Give ample water and a generous amount of fertilizer in late spring. They will look much better if deadheaded and if snails and slugs are controlled. Only cut off the part that has flowered, as new buds will begin developing nearby. When a stem has no more discernible buds, it can be cut back to the ground to allow a new stem to develop.
