Garden thugs, a national list of invasive and potentially invasive garden plants

The Garden Plants Under The Spotlight (GPUTS) report (Roush et al. 1999), represented many months of work in developing a national list of Australia's 100 worst invasive garden plants or garden thugs. However, the base list that these plants were drawn from was made up of 720 naturalized flora plus a number of prohibited or noxious weeds. Since the release of the GPUTS report, there have been numerous requests for copies of the complete list from within the nursery industry and other interested parties. This paper represents a completely revised version of 958 species. The term 'garden thug' was possibly coined by Edward Augustus Bowles in the early 1900s, in reference to garden plants that were misbehaving and creating problems within the garden. It is no great stretch to apply this same term to plants that have escaped from the garden.
