Originally from South Africa, Black-eyed Susan escapes from Queensland and New South Wales gardens. It is a weed in several countries around the world. The name refers to the bright yellow-orange flowers, which have a contrasting black centre. Roots form at the nodes of the stem when they come into contact with the soil, forming new plants. Like Singapore daisy, the material needs be completely removed by hand, bagged, and taken off site.
