Canna [or canna lily, although not a true lily] is a genus of nineteen species of flowering plants. The closest living relations to cannas are the other plant families of the order Zingiberales, that is the Zingiberaceae [gingers], Musaceae [bananas], Marantaceae, Heliconiaceae, Strelitziaceae, etc. Canna is the only genus in the family Cannaceae. Such a family has almost universally been recognized by taxonomists.
The species have large, attractive foliage and horticulturists have turned it into a large-flowered and bright garden plant. Although a plant of 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 can enjoy at least 6–8 hours average sunlight and are moved to a warm location for the winter.
The name Canna originates from the Celtic word for a cane or reed.
