Mysore raspberry

Also known as White blackberry or Hill raspberry, Mysore raspberry is originally from India and South-East Asia. It forms dense, impenetrable thickets and has become invasive in some areas where it has been introduced, including Hawaii and the Galapagos Islands. It is a Class 3 noxious weed around the North Coast region. Mysore raspberry is a large scrambling shrub, 3-4.5 metres high, with sharp, hooked thorns. Its leaves are hairy and made up of from five leaflets to nine leaflets, 2.5-6 cm long, with toothed edges. The upper side is dark green while the underside is white Pink or mauve […]


Long-leaf willow primrose

Long-leaf willow primrose is an invasive aquatic plant from South America which forms dense colonies in slow-moving and static waterways. It was first introduced to Australia as an ornamental plant, and has invaded wetlands and riparian areas near Sydney, on the Central Coast of NSW and near Brisbane, in Queensland. If no control action is taken it will dominate temperate and tropical wetland and riparian systems throughout Australia, according to the NSW Department of Primary Industries. Long-leaf willow primrose is a Class 2 noxious weed across the North Coast, except for the Nambucca local-government area where it is Class 1. […]



Cecropia are rapidly growing trees originating from tropical America. They are pioneer species that can quickly establish in disturbed areas and have become weeds in South America, Malaysia and Africa. In the past, Cecropia species (including Cecropia peltata) have been imported into Australia for private plant collections, but all known plants have been destroyed due to their invasive potential. They are listed as Class 2 noxious weeds across the North Coast region. They are a rapidly growing tree, usually 10-20 metres tall, but can reach up to 25 metres. The plants can be distinguished by the large U-shaped leaf scars […]


Cockspur coral tree

Cockspur coral tree (also known as Cocks comb coral tree) is a deciduous shrub or tree from South America. Originating from northern Argentina, eastern Brazil, Bolivia, Paraguay and Uruguay, it can grow to 10 metres. It has been commonly grown in Australia as an ornamental plant and has become invasive along waterways in coastal NSW north of Sydney. It is gazetted as a Class 3 noxious weed in the Bellingen, Nambucca, Coffs Harbour and Clarence Valley local-government areas and as a Class 4 noxious weed on the Far North Coast. It usually grows to between five metres and eight metres […]

Common pampas grass 

Pampas grass

Pampas Grass is a large, long-lived, perennial tussock grass more than two metres high with prolific fluffy seed heads (up to three metres high). It is common in open, sunny places with damp soils and on disturbed sites. Sharp, cutting bluish-green leaves grow up to two metres long. Flowers occur in summer, developing well above the foliage in two sex forms on separate plants. Female flowers are white and fluffy, while bisexual flowers are yellow, pale pink or pale mauve and almost hairless. Each plume produces up to 100,000 seeds in late summer/autumn and up to 50 plumes can occur […]

Mistflower in flower 


Mistflower is distinguished by multicellular, purple-striped, non-glandular hairs on upper stems and leaf stalks. It has flat-topped terminal clusters of small white flowers (florets). Its florets are all tubular. Seeds have hairs on ribs. The seeds are five-angled, black, 1-2 mm long, topped with bristles 3-4 mm long which readily separate from seeds. Stems are purplish and cylindrical. Leaves are opposite, mostly 7.5 cm long and 2.5 cm wide, toothed along the edges and tapered at each end. Flowers occur in white heads, 4 mm to 6 mm wide, in flat-topped showy clusters (corymbs). Bracts around the heads are hairy. […]


Mother of millions

Mother of millions is a native of Africa and Madagascar and was introduced to Australia as a garden plant. It is a serious weed on the coast and the north-west slopes and plains of New South Wales. Consequently, it is a declared noxious weed in these areas. This perennial herb is a smooth, fleshy, succulent plant growing to one metre or more in height. It is distinguished by erect, simple, cylindrical stems. Leaves are about 2 cm-15 cm long and succulent, without a stalk. They are pale grey to speckled brown with dark green patches and a shallow groove on the […]



Blackberry is a perennial shrub, with arching, entangling stems arising from a woody crown; forming thickets up to several metres high. Canes can be arched or trailing, up to seven metres long. They are green or purplish/red, smooth or moderately hairy, round or angled, with many curved or straight prickles of different sizes. Leaves are compound with three or five oval leaflets, which are usually dark-green above and lighter green beneath, with small teeth around the edges. Flowers are 2 cm to 3 cm, growing in clusters on the side of branches. They have five sepals and five white or […]


Koster’s curse

Koster’s curse is a declared Class 1 Noxious Weed in NSW and is the target of a national eradication program. It is a highly invasive shrub, growing up to five metres tall and has the potential to spread rapidly over many parts of Australia. Koster’s curse forms dense thickets, which can smother pasture and native vegetation in a similar manner to lantana. It is quick-growing and could cause major problems for primary industries. It invades disturbed areas including the edges of clearings and stream-banks, along fence lines, paths and roadways. The weed prefers humid tropical lowlands and therefore could spread […]
