This evergreen groundcover grows about 1m tall in the wetlands, sun or semi shade. It is frost resistant, fast growing, and bears white flowers in summer. It makes a very attractive back drop to a wetland garden as the leaves are a pretty green and interestingly ‘pleated.’ Birds strip the leaves for nest building and the seed eaters enjoy the fruits. The leaves are palatable and are browsed by game. It is the larval host plant to the Long-horned Skipper, Lesser-horned Skipper, Twilight Brown and Gold-spotted Skipper butterflies. Strangely, it is also eaten by dogs. It is used traditionally to treat bruises. The name is derived from the Latin seta=a bristle and aria = pertaining to: referring to the bristly awns in the involucrum. A leaf-like structure occuring just below the flower.
