Dyschoriste depressa (L.) Nees
Note: the identity of this species is not certain, and it is possible that plants naturalised in Australia actually belong to another African species (i.e. Dyschoriste radicans).
butterfly heaven, dyschoriste
Native to southern Africa (i.e. the eastern parts of South Africa).
This species is currently only naturalised in the Moreton district in south-eastern Queensland.
Dyschoriste (Dyschoriste depressa) is an emerging environmental weed that is found in parks, gardens, lawns, parks, roadsides, footpaths, and waterways in Brisbane. It prefers wetter environments such as creekbanks and wetlands, but will also grow in drier habitats. Mowers and slashers are thought to be one of the agents of its dispersal to new areas.
This species has been observed to develop into very dense monocultures, particularly along waterways in the Kedron Brook, Enoggera Creek and Ithaca Creek catchments. Such infestations have the potential to damage riparian ecosystems and reduce biodiversity, and may also restrict the flow of water.
