About this weed
In Western Australia there are two native species of Centaurium and seven naturalised species. The species are difficult to tell apart and further study is needed. All have pink or red-pink flowers except C. maritimum which has yellow flowers.
Common Centaurium is a biennial or annual herb growing between 0.05 and 0.5 m high. It produces many simple pink or red-pink flowers over summer that are held erect on more or less branched hairless stalks. How it was introduced is not documented but may have been used as a garden plant.
