Impact
Impact
Canna lily (Canna indica) is regarded as an environmental weed in New South Wales and south-eastern Queensland. It is mainly found north from Macquarie Pass in New South Wales, and is of particular concern in the Sydney, Blue Mountains, and North Coast regions. However, this garden escape is probably most common and invasive in south-eastern Queensland, where it appears on the list of the 200 most invasive weeds. It is considered an environmental weed because it forms large dense clumps, particularly along waterways, and replaces native aquatic and wetland species.It is also regarded as an invasive species in other parts of the world and is listed in the Global Invasive Species Database. In Hawaii and Fiji it also becomes naturalised in disturbed wetter forests and in forest clearings.
