Canna tuerckheimii Kraenzl. is a giant wild species; green foliage, oblong shaped, branching habit; spikes of flowers are erect, self-coloured crimson, staminodes are long and narrow, edges regular, petals purple, fully self-cleaning, blooms open in the early morning; fertile both ways, not self-pollinating or true to type, capsules ellipsoid; rhizomes are thick, up to 7 cm in diameter, coloured white and purple; tillering is prolific.
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 Tuerckheimii is the correct name, but Dr. Nobuyuki Tanaka considers that the correct name is C. latifolia.
