    Sorry to disagree, but full sun is not essential for success with Zantedeschia aethiopica. I have grown these plants for over 25 years in semi shade. I live on the edge of a forest and have no area that gets full sun on my entire lot. I bring them inside in the winter, and of course there they get minimal sun. That said, I would acknowledge that if I could grow them in full sun I might get heavier bloom.

      I can attest to the minimal light requirements. This is the first winter where I've not stored the bulbs in the fridge and can say they are growing just fine at a SW window. I also agree that more sun equals more blooms, but you need a lot more water.

        I have been looking for any of the pink forms. Any sources for those?

          Plant Delights used to sell the "Pink Mist' variety, but no more. Do a search and see what you come up with.
