Description
Canna indica is a long-lived (perennial) herbaceous plant, 90-180 cm tall.
The upright (erect) stems (1-2 m tall) are sturdy, hairless (glabrous) and green in colour. The alternatively arranged leaves consist of a stem-clasping sheath at the base and very large, spreading, leaf blade (20-60 cm long and 10-30 cm wide). The leaf blades are elongated or oval (elliptic) in shape but come to a point at the tip (they have acute or acuminate apices). They are hairless (glabrous), have entire margins, and narrow at the base where they join to the top of the leaf sheath.
The flowers can be either red, yellow or occasionally red and yellow (yellow with red spots or vice versa) and are quite showy. They are borne singly or in pairs (monochasial cymes) and arranged into larger branched clusters (with 6-20 flowers) at the tips of the flowering stems. Each flower appears to have five 'petals' but these are actually other floral structures (staminodes and petaloid filaments) that have become modified to imitate petals. The petals are actually the three bract-like structures below these false 'petals' (4-6.5 cm long and 0.4-0.7 cm wide). They are fused together at the base (into a perianth tube 5-15 mm long) and their margins are curved inwards
