Arum lily (Zantedeschia aethiopica)
Arum lily (also commonly named funeral lily or death lily because it was once popular as a funeral flower) is a garden escapee that is now considered an environmental weed. Arum lily is a long-lived plant that is 1-1.5 m tall. It is known for its large, white flowers and recognisable leaves. Arum lily can be toxic to humans, livestock, horses, dogs, cats and birds.
Arum lily prefers wet, sunny areas but can also grow in full shade. It is hardy and can tolerate waterlogging, fire, occasional frost and salt. It can grow in tropical and cold areas. In Helensburgh, it is common in swampy areas and along drainage lines and creeks, and has now spread into the Royal National Park and Garrawarra State Conservation Area. It spreads by seed and plant parts.
Removing large clumps of Arum lily is time consuming and requires many years of follow-up.
If you have Arum lily on your property or close-by, please do all you can to remove this invasive weed.
