''Canna flaccida'' is a species of the ''Canna'' genus, a member of the family Cannaceae. The species is indigenous to the wetlands of south-eastern and south-central USA from Texas to South Carolina. It is also reportedly naturalized in India, the Philippines, Mexico, Panama, Cuba, the Dominican Republic, Peru and southern Brazil.〔(Kew World Checklist of Selected Plant Families, ''Canna flaccida'' )〕 ''Canna flaccida''was a parent to many of the early-hybridised cannas originally known as orchid flowered cannas, but now correctly named as Italian Group cannas. It grows well as a water canna. Originally described by the early American explorer, William Bartram, when he found these plants blooming near the rivers of coastal Georgia. The seed floats down the rivers and becomes easily established on shorelines. Introduced to England in 1788.〔Johnson's Gardeners Dictionary, 1856〕 ''Canna flaccida''is a perennial growing to 1.5m. It is hardy to zone 10 and is frost tender. In the north latitudes it is in flower from August to October, and the seeds ripen in October. The flowers are hermaphrodite.〔Cooke, Ian, 2001. The Gardener's Guide to Growing cannas, Timber Press. ISBN 0-88192-513-6〕 == Taxonomy == In the last three decades of the 20th century, ''Canna'' species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. In this case both agree that ''C. flaccida'' is a distinct species, and the DNA work by Prince and Kress at the Smithsonian Institution confirms its uniqueness.〔Tanaka, N. 2001.
