Canna patens (Roscoe) Tb. Tanaka

A medium sized wild species; green foliage, very small, ovoid shaped, arching habit; triangular stems, coloured green; spikes of flowers are erect, yellow with a wide red margin, staminodes are long and narrow, edges regular, petals yellow, partial self-cleaning; fertile both ways, self-pollinating and also true to type, capsules globose; rhizomes are thick, up to 3 cm in diameter, coloured white; tillering is prolific.

Introduced by Aiton, and confirmed by Roscoe. Native of Mexico, thought by Professor Maas to be a synonym of C. indica L. but Dr Tanaka has categorised this as a separate species, confirmed by DNA sample.
