Boneseed (Chrysanthemoides monilifera ssp monilifera) is declared noxious in the Illawarra District Weeds Authority control area (including Kiama, Shellharbour and Wollongong council areas).

The weed control class is 1. This means that:

The plant must be eradicated from the land and the land must be kept free of the plant”.

Description: A perennial upright shrub to 3m high, Boneseed has woody branched stems and elongated oval shaped leaves with irregularly serrated edges. New growth is typically covered by white downy cotton-like material. Boneseed has yellow daisy like flowers, with 4-8 petals borne in late winter/spring. It has round fleshy green fruit that turns black when mature and contains a single smooth round seed 6-7mm in diameter. The seed is bone coloured when dry, hence the name ‘boneseed’. A native of South Africa.

Problem: Very invasive, out competing native vegetation. Relatively easy to control but regenerates and spreads quickly after disturbance. Capable of invading a wide range of habitats in the area.
