White shrimp plant (Justicia betonica) is regarded as an environmental weed in Queensland and as a potential environmental weed or "sleeper weed" in other parts of northern Australia. This garden ornamental has escaped cultivation and invaded roadsides, parks, urban bushland, disturbed sites and waste areas. It prefers damper sites and is particularly invasive along waterways and in riparian areas., White shrimp plant (Justicia betonica) is quickly becoming widespread and common in waterways in south-eastern Queensland. It forms dense infestations that replace native species and was recently ranked among the top 200 most invasive species in this region. This species was first recorded as naturalised in New South Wales in the year 2000, in Ukerebagh Nature Reserve at Tweed Heads in the far north-east corner of the state., This species is is also regarded as being invasive in Hawaii, where it often escapes cultivation and forms large stands of vegetation.
