Cannas (Canna spp.) are a genus of beautiful, easy-to-grow plants with showy flowers that come in red, pink, yellow, orange, and cream. Canna leaves are wide and long (resembling banana leaves) in green, bronze, or multicolored patterns. Most cannas grow up to 6 feet tall and occasionally as tall as 8 feet. These plants grow from rhizomes, underground stems that send up plant shoots.
Throughout their hardiness zone, cannas can be left in the ground as true perennials. In colder climates, the rhizomes can be lifted in the fall, stored over winter, and replanted in the spring. Best planted from rhizomes in the early spring, cannas can take a few weeks to sprout. But then they grow at a fairly quick pace and typically flower in their first year.
