Creeping lantana (Lantana montevidensis)

Creeping lantana is a sprawling shrub. It is a weed of pastures along north and central coast of NSW and southern Qld.


How does this weed affect you?

Creeping lantana occurs on the north and central coast of NSW and south-eastern Qld. It is a weed of unimproved pastures. It has been suspected of poisoning cattle. 

Creeping lantana is also highly toxic to humans, and can cause serious illness and death. All parts of the plant, particularly the green berries, are poisonous if ingested, causing vomiting, diarrhoea, muscular weakness and respiratory distress. The plant is also a skin and eye irritant. 

What to do if poisoning occurs:

  • If the patient is unconscious, unresponsive or having difficulty breathing dial 000 or get to the emergency section of a hospital immediately.
  • If the patient is conscious and responsive call the Poisons Information Centre on 13 11 26 or your doctor.
  • If going to a hospital take a piece of the plant for identification.

What does it look like?

Creeping lantana is a sprawling shrub with weak stems and aromatic leaves when crushed. Its flowers change from pale to dark purple with yellow centres.
