DESCRIPTION
Robust evergreen herb (1–2 m high) with a thick, branching, underground rhizome; leaves taper into slender petioles that form a sheath (tubular structure that clasps stem) around the main stem.
Leaves: Green, hairless, simple, elongated or oval (20–60 cm long and 10–30 cm wide), tapering to a point, margins entire, sheath clasping the stem similar to Canna × generalis Bailey, which also has purple-bronze leaves.
Flowers: Red or orange, usually yellow below, narrow (40–50 mm long), borne singly or in pairs at the tips of the flowering stems as opposed to Canna × generalis, which are yellow, red, orange, white or other colours, broad (80–90 mm long).
Fruits: Capsules (dry fruits that open at maturity), green turning brown as they mature, spiny, three-valved containing hard black seeds.

IMPACTS
Forms dense clumps out-competing native plant species. It also restricts the flow of water contributing to increased sedimentation and flooding. Dense stands can also restrict access to water. It is also an alternative
host of a number of crop pests, including banana bunchy top virus, cucumber mosaic virus and tomato spotted wilt virus, and a range of other pests that cause pathogenic diseases. Chemical extracts have a negative impact on snail species (Tripathi and Singh, 2000).
