Canna tuerckheimii Kraenzl. is a species of the Canna genus, belonging to the family Cannaceae. Native of Belize, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua, Panama, Colombia and Ecuador at altitudes of 500-2,000m (1,600 - 6,500ft). Johnson's Dictionary of 1856 reports that it first entered England in 1820 as Canna latifolia, meaning 'broad-leaved'.
It is a perennial growing to 4-5m. 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 (have both male and female organs).

[edit] Taxonomy
In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Professor Paul Maas in conjunction with his wife Dr. Hiltje Maas, both from from Holland and Dr. Nobuyuki Tanaka from Japan. Inevitably, there are differences in their categorisations and Dr Tanaka considers that the correct name is C. latifolia.
