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’.
Professor Paul Maas and his wife Dr. Hiltje Maas, consider C. tuerckheimii is the correct name, but Dr. Nobuyuki Tanaka considers that the correct name is C. latifolia.
