Green cestrum (Cestrum parqui) is regarded as significant environmental weed in New South Wales and Queensland. It is currently listed as a priority environmental weed in three Natural Resource Management regions, and is also regarded as a sleeper weed in other parts of the country. In New South Wales it is of most concern on the north coast and in the wider Sydney and Blue Mountains region. In Queensland it is listed in the top 100 invasive plants in the south-eastern part of the state. It is also scattered in bushland around Adelaide and causing some concern in the warmer regions of Victoria., Green cestrum (Cestrum parqui) grows vigorously and has been known to outcompete other vegetation on alluvial floodplains in Queensland. It has also formed reasonably dense infestations along degraded creek-banks and in overgrazed pastures. As it can form extensive stands along the edges of forests and waterways, it replaces indigenous plants in these habitats and prevents their regeneration., The roots, stems, leaves and fruit of green cestrum (Cestrum parqui) are very toxic to livestock, domestic animals and humans, and stock losses have been reported.
