Comm<strong>on</strong> name: Canna Lily Latin name: Canna indica, Canna x generalis<br />
FAMILY: CANNANACEAE<br />
ORIGIN:<br />
Noxious Weed Category: n/a<br />
Descripti<strong>on</strong><br />
Habit: Erect, herbaceous perennial to 2m high with no true stems. Stems are a collecti<strong>on</strong> of tightly furled<br />
leaf bases. Roots extensive and a fleshy rhizome is formed underground. Leaves: Leaves Dark green to<br />
multi coloured and striped, large (60 x 25cm), arranged alternately <strong>on</strong> ‘stems’. Flowers: Tubular flowers<br />
(yellows oranges, reds and pinks) formed in asymmetrical clusters. Spring-Autumn. Fruit: Black, globular<br />
seeds (5-7mm l<strong>on</strong>g) borne in capsule, and spread by birds. Roots: Aggressively fibrously rooted.<br />
Ecology: Well suited to damp/boggy ground in full sun positi<strong>on</strong>s, but because it can spread by <str<strong>on</strong>g>the</str<strong>on</strong>g><br />
aggressive, creeping rhizome, it can invade into semi-shade. When ripe, <str<strong>on</strong>g>the</str<strong>on</strong>g> fruit capsule is unremarkable<br />
in colour but <str<strong>on</strong>g>the</str<strong>on</strong>g> 5mm seeds are spread by birds and by c<strong>on</strong>taminated and dumped green/waste.<br />
Dispersal: Seed, usually spread by birds but also often as a c<strong>on</strong>taminant of garden waste/mulch and to a<br />
lesser extent in flowing water of riparian systems.<br />
