As their name suggests, wetland plants grow naturally in wetland areas with their roots either permanently submerged under water or in the boggy damp zone.
Wetlands are a natural filter. They remove nitrates, phosphates, heavy metals, and faecal matter and other impurities from waterways and from riparian areas. This in turn leads to regeneration of aquatic and birdlife making wetlands a critical component of a healthy environment.
Species that are predominantly used in wetland plantings include the reed species such as Schoenoplectus tabernaemontani, Baumea articulata, Baumea rubiginosa, Baumea teretifolia, Typha orientalis, Eleocharis sphacelata, Eleocharis acuta, Juncus pallidus, Juncus gregiflorus, Isolepsis nodosa, Apodasmia and the sedge species Carex secta, Carex virgata, Carex lessoniana, Carex germinata, Cyperus ustulatus and also Phormium tenax and Cordyline australis.
