Calla lily, another white legacy flower

I inherited this white Calla lily from the previous community gardener, who seemed to have amassed an interesting collection of white flowers during her regime. While googling, I came across the term 'moon garden', describing a garden filled with only white flowers. In my hands, this plot is no longer a moon garden since I am rather fond of pink flowers.

Family: Araceae, Zantedeschia sp., probably aethiopica
