"Canna coccinea" is a species of the "Canna" genus, belonging to the family Cannaceae, a native of northern Argentina. Introduced to England from South America in 1731. [Johnson's Gardeners Dictionary, 1856] [http://apps.kew.org/wcsp/prepareChecklist.do?checklist=selected_families%40%40080200320082134980 Kew Gardens, Checklist of plant families] ]

It is a perennial growing to 2m. 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 Netherlands [Segeren, W. & P. J. M. Maas. 1971. The genus Canna in northern South America. Acta Bot. Neerl. 20(6):676.] and Nobuyuki Tanaka from Japan. There are differences in their categorisations.

Dr Maas considers C. "coccinea" to be a synonym of "C. indica" L., however, Dr Tanaka's studies have revealed that a DNA assay demonstrates that the "C. indica" complex can be clearly distinguished from other taxa, as a result he recognises it as a separate species.Tanaka, N. 2001. Taxonomic revision of the family Cannaceae in the New World and Asia. Makinoa ser. 2, 1:34–43.]

"Canna coccinea", Mill.

Full heads of raspberry red flowers held high over the deeper green leaves. Orange or red staminodes (usually 2). The inflorescence stalk generally elongated and not branched. The fruits contain 3 to 5 seeds. The axis (inflorescence stalk) "distinctly triquetrous". Note: triquetrous: triangular in cross-section and acutely-angled; with three distinct longitudinal ridges.
