Common Centaury (Centaurium erythraea), sometimes known as Feverwort. A traditional medicinal and bittering herb in its home range through the Mediterranean and Central Asia, it was likely brought to Australia intentionally as a domestic herb and garden flower. Now a widespread environmental weed, and an able colonist of grasslands and grassy woodlands in Victoria. Recorded here from the 1880s, with the first specimen being collected from Studley Park. The photographed plant was found on the suburban edge of the Gresswell Forest, where it was flowering quite early.
