Arum lily, like many Australian weeds is an escaped garden plant. It is usually found in wet areas along creeks or irrigation lines and If not controlled can form large dense clumps.
Unlike many weeds the most effective time to control arum lily is when it is mature and flowering, although smaller plants can be removed by hand.
Arum lily is toxic to stock however it is unpalatable therefore issues are rare. It outcompetes productive farm land and can choke up watering areas.
Due to its large green leaves and distinctive white flowers it is often sold at local markets or by flower vendors.
A faded icon means occasionally.
Due to legal requirements the PHBG does not recommend specific herbicides.
