Cannaceae . Indigenous to the wetlands of south-eastern USA. It 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.It 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 .Synonyms

In the last three decades of the 20th century, "Canna" species have been categorised by two different
taxonomists ,Paulus Johannes Maria Maas fromthe Netherlands andNobuyuki Tanaka fromJapan . In this case both agree that "C. flaccida" is a distinct species, and the DNA work byPrince and Kress at theSmithsonian Institution confirms its uniqueness."Canna flaccida" Salisb.
It is aquatic species, with narrow, blue-green (glaucous) leaves, very pretty, large, canary yellow flowers growing in clusters at the tops of long stalks. The lip of the flower is wavy. Flowers emerge in the evening and wither in the heat of the following day, the only member of the genus that behaves in this manner, all others open early in the morning and are strong enough to survive at least one day. It grows as a marginal plant in up to about 15cm of still or slow-moving water.
