This plant hardly produces fruits, and even more hardly theres a bird to eat them and spread seeds. The most common way this plant spreads itself is by rhyzomes. So, better plant in closed gardens, beds, pots, to keep it from spreading uncontrolably.

Zantedeschia aethiopica(L.) Sprengel is well documented as invasive in Australia, South Pacific islands, and along the coast of California. I do not know whether particular cultivars are more or less invasive than the species. The plant is difficult to remove from wetlands, and its invasiveness there threatens many native species that will grow no place else. Gardeners who plant this species should be sure to keep it away from marshes, riparian zones, ponds, and other wetlands, and are reminded to steward any native plant habitats in the vicinity to keep them free from horticultural escapes.
