About
Arum lily (Zantedeschia aethiopica), like many Australian weeds, is a plant that escaped gardens to invade native ecosystems. The sale of arum lily is now banned in Western Australia.
Arum lily thrives in wet areas along creeks and irrigation lines. If left uncontrolled it can form dense clumps, outcompeting native vegetation, reducing land productivity, and choking up watering areas.
Unlike many weeds, the most effective time to control arum lily is when it is mature and flowering. However, smaller plants can be removed by hand.
Arum lily is toxic to livestock. It is unpalatable so poisonings are rare, but animals may consume it during times of feed scarcity.
