Paraguay burr (or Acanthospermum austral) is native to South America and the Caribbean and is a creeping plant that can often emerge on roadsides, footpaths, gardens and waste areas.
This weed is commonly spread by its burrs becoming attached to animals, clothing and vehicles, but seeds and stem fragments may also be spread by soil, water, mowers and other road maintenance activities.
This species was first recorded in south-eastern Queensland in 1994, yet it has now been widely naturalised between the Hunter Valley and Wollongong.
Paraguay burr is usually easily recognised by its hooked burrs and creeping stems that can form dense mats of vegetation. The younger stems are green and hairy, while older stems tend to be woody in nature.
Residents can play an important role in stopping the spread of this invasive weed. Anyone who sees it is encouraged to contact Cessnock City Council’s Weeds Officers on 4993 4100.
