The canna lily plant is a rhizomatous perennial with tropical-like foliage and large flowers that resemble that of iris. Canna lilies are low maintenance and easy to grow, and both their flowers and foliage offer long lasting color in the garden. The flower color may be red, orange, or yellow. Depending on the variety, foliage color varies from green to maroon, bronze, and variegated types. 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.
