This species is regarded as an environmental weed in Victoria and Tasmania, and a potential environmental weed or "sleeper weed" in South Australia. Small populations have invaded dry coastal vegetation, lowland grasslands, grassy woodlands and rocky outcrop vegetation in Victoria.
It has also been reported from Scott Creek Conservation Park in Adelaide and in urban bushland in the Hornsby Plateau region to the north of Sydney Harbour.
