Arum Lily Winter Weed

If you have Arum Lily weeds growing on your property, now is the time to control them. Arum Lilys are dormant over summer, waiting for the winter rain to sprout and produce big white flowers. They can look beautiful; however the Arum Lily is a declared weed. It likes to grow in wet areas; it smothers sensitive wetland species and disturbs frog breeding habitat.

You can help map this invasive weed in our Shire by either using the Inaturalist app or reporting populations to the Environmental Sustainability Officer.

Small plants can be dug out, though large areas will need spraying. The flowers produce berries that birds eat and spread to new areas. Remove seed heads and dispose of them correctly. Use the right chemical (Chlorosulfuron) as glyphosate alone does not kill the bulb.
