Canna Flower Plant For Outdoor Gardening

Planting And Care Cannas do best with a good supply of water, so water the plants during the summer if the rainfall is less than 1 inch per week. Keep a thin layer of mulch around cannas to help retain moisture as well. Stake tall varieties if needed. As flowers fade, deadhead to promote continued flowering. Canna Care While typically grown as annuals in cooler regions, given the proper conditions, canna lilies can colour the garden year after year. They like plenty of heat, so place them in full sun. They can also tolerate partial shade. Cannas like moist conditions too, but will tolerate nearly any well-draining soil that is either neutral or slightly acidic. They appreciate bog-like conditions as well. The soil should also be rich in organic matter. When growing cannas in the garden, placing them in mixed borders or group plantings will offer the most dramatic effect. These perennials come in a vast variety of color and boast immense, often-veined, paddle-shaped leaves and sheathing leafstalks in shades of green or bronze.
