Canna or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species. All of the genus's species are native to the American tropics and naturalized in Europe, India and Africa in the 1860s. Although they grow native to the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world, as long as they receive at least 6–8 hours average sunlight during the summer, and are moved to a warm location for the winter. See the Canna cultivar gallery for photographs of Canna cultivars.
