Boneseed (Chrysanthemoides monilifera subsp. monilifera (L.) T.Norl.) appears to have been a popular although isolated garden plant on the Eyre and Yorke Peninsulas, where it has since escaped and established wild populations. Infestations in the Eyre and Yorke regions are the western most in South Australia and despite being recorded in twenty nine locations, currently impact an area of less than 190 ha of bushland. Boneseed is growing in northern mallee areas with rainfall as low as 200mm and in areas of up to 500mm of rainfall in blue gum, Eucalyptus petiolaris (Boland) Rule, and sugar gum, E. cladocalyx F.Muell, country in the south
