Occurrence: Self-heal is a weed of damp places e.g. well-watered lawns and beside streams. In wetter climates it is more widely distributed.
Self-heal is sometimes thought to be native to Australia as well as to the northern hemisphere. Even if this is so, in the Central Goldfields Self-heal grows in weedy or greatly modified vegetation, and is unlikely to be native to the area. Self-heal has been used as a medicinal plant in Europe and Asia.
Photos all: Self Heal. The leaves are in pairs, and the usually purple flowers are in a dense cylindrical cluster.
