Weed Potential 
As a weed the White Arum Lily grows in moist, coastal regions of Australia and is invasive infesting native wetland habitats and along water courses. It is fast growing and once established the plant decreases the light for native seedlings to grow. 

This perennial is long lived and can form large clumps, tolerating an open sunny to heavy shaded position and tolerating most soil types. Mature plants produce masses of viable seeds. The seeds are dispersed by water or by animals and plant fragments are spread in garden waste or soil. 

Control methods include physically digging out small infestations including the roots. Fruiting stems should be cut and bagged where possible then all plant material should be removed off site and destroyed.  

Spraying plants with a non-selective herbicide may be ineffective as the leaf has a very waxy surface inhibiting penetration and drifting spray may contaminate water courses.
