Native wintercress is a small annual brassica from Tasmania, closely related to the garden watercress relatives. It is grown as a leafy green that tastes a bit like rocket, and it is critically endangered in the wild.
Barbarea australis, commonly known as native wintercress or riverbed wintercress, is a morphologically and ecologically typical Barbarea species with an unusual distribution: it is an endemic and threatened species from Tasmania. The leaves have a large end-lobe and only few side lobes, much like the leaf-shape of Barbarea stricta and Barbarea orthoceras. With regard to defence chemicals (glucosinolates), it is similar to other members of the genus.
Although the plant remains critically endangered in the wild, Native wintercress is available for home garden cultivation. All above-ground parts of the plant are edible, with the leaves tasting similar to rocket.
