Raoulia australis forms mats of firm silvery green foliage, up to 40 in (1 m) across. The tiny leaves closely cover the stems, and are densely hairy. Tiny, yellow daisy flowers in summer.
Raoulia australis is found in bare ground, river beds, river terraces and open short tussock grasslands, in lowland to montane, in North Island and South Island, New Zealand. It can be grown in a rock garden, in full sun and well-drained soil.
