Cannas thrive in hot, humid weather. They are thirsty plants and need a consistent supply of water throughout the growing season. In warm areas, cannas grow well in full sun or in partial shade. In cooler areas they grow best in full sun.
In warm climates (USDA hardiness zones 8 to 10), canna bulbs can be left in the ground over winter, and the plants perform reliably as perennials, coming back year after year.
