Canna (redirected from canna lily)

canna [Lat.,=cane], any plant of the genus Canna, tropical and subtropical perennials, grown in temperate regions in parks and gardens for the large foliage and spikelike, usually red or yellow blossoms. Today, most cultivated cannas are hybrids, but two species are found wild in the S United States, one called Indian shot because of the hard shotlike seeds. C. edulis, Queensland arrowroot, is cultivated in the tropics for its rootstock, a commercial arrowroot starch. Canna is classified in the division Magnoliophyta, class Liliopsida, order Zingiberales, family Cannaceae.

canna

Any of the tropical herbaceous plants that make up the family Cannaceae, of the ginger order (Zingiberales), containing a single genus with about 55 species, found from southeastern North America through South America. Cannas have rhizomes with erect stems growing to 10 ft (3 m) high. The green or bronze leaves are spirally arranged. The flowers are asymmetrical. Spotted variations of the scarlet, red-orange, or yellow flowers sometimes occur. The genus Canna is widely grown for ornamental use. C. edulis, from Peru, has edible, starchy rhizomes.

Canna 

the only genus of the family Cannaceae. The plants are large perennial herbs with strong stalks; they often have tuberous thickened rhizomes. The leaves are large, broad, pinnately veined, and sheathed. The flowers are irregular, monoecious, large, and usually brightly colored; they are gathered into a paniculate terminal racemose or inflorescence. The perianth is binate. Only half of the anther of one stamen is fertile; the remaining half and the other stamens are petaloid and are stami-nodia. The stigma has a petal-like style. The ovary is inferior and trilocular. The fruit is a capsule. There are approximately 50 species, found in tropical and subtropical America. There are approximately 1,000 garden varieties (for example, Canna × genera lis and C. × hortensis), which are used in cultivation. They differ in color, leaf color, size, height of stalk, and form of the staminodia. The species Indian shot (C. indica) is cultivated in Europe as a greenhouse ornamental; C. edulis is grown in the Americas and Australia for its rhizomes, which contain starch from which the queensland arrowroot is obtained.
