This lily with white spathes around yellow flower spikes is widely used as a cut flower. However, it is now a widespread environmental weed that can engulf gutters, streams, waterways and wetland bogs and may be toxic if eaten. It is a perennial to 1.5 metres tall with broad leaves to 1 metre long present all year. Seeds are produced in green berries inside the spathes.
The cultivar ‘Green Goddess’ is also invasive. However, the other Zantedeschia species with coloured spathes and winter-dormant tubers are safe.
