Around here people grow Zantedeschia aethiopica pretty much as an ordinary garden plant. Across the street from me they are along the side of the house and down around the corner from me there are a whole bunch of them all along a driveway. I have also read they can be grown pondside but haven't seen anyone growing them like that here. If you have more than one you could try both ways. I think I could almost say they grow like weeds here.
