Invasive Plant
Arum lily
Zantedeschia aethiopica

This white lily with large spathes is widely used as a cut flower. The plants of the Arum lily will engulf gutters, streams, waterways and wetland bogs. It is now a widespread environmental weed! The green form called 'Green Goddess' is also invasive and can also be found clogging up natural waterways.



  • These plants produce prolific amounts of seed that wash down gutters and streams and readily germinate. It also produces large amounts of small rhizomes that are easily spread in contaminated soil. Birds and small mammals also disperse the seeds through their droppings.
  • Any moist soil will be quickly infiltrated.

Though these are popular cut flowers, the use of this plant must be discouraged for the home garden. Its spread must be stopped.
