distribution_en:

description_en: Genus of about 50 species of rhizomatous herbaceous perennials, mainly from forest margins and moist, open areas in forest in Asia and tropical North and South America. Cannas are cultivated for their large, alternate, paddle-shaped leaves, 30-60cm (12-24in) long in most species and cultivars; they are pinnately veined and sheathed at the bases. The racemes or panicles of brightly coloured flowers are also attractive, each asymmetric flower having 3 petals joined into a tube at the bases, 3 sepals, and showy stamens. The flowers are usually produced in pairs from the axil of each bract. Hundreds of hybrids have resulted from complex crosses between various species; they are often grouped under the names C. x generalis and C. x orchioides. As the distinctions between these hybrid groups have been blurred by further inter-breeding these names have not been used in the descriptions below. In frost-prone areas, use cannas in summer bedding and lift for winter, or grow in containers on a patio or in a cool conservatory or greenhouse. In warmer areas, grow in a border.

hardiness_en: Half hardy to frost tender.

cultivation_en:

propagation_en: Sow seed at 21°C (70°F) in spring or autumn. Chip seed or soak in warm water for 24 hours before sowing. Divide rhizomes into short sections, each with a prominent "eye", in early spring. Pot on and start into growth at 16°C (61°F); water sparingly at first.

pests_en: Susceptible to red spider mites under glass. Slugs and caterpillars may be a problem outdoors.
