Answer: Calla lillies (Zantedeschia) are originally from South Africa and should bloom for you this summer. They do not tolerate cold winter weather. You must be lift them each fall before the first frost, and store them dry over the winter. Replant them in the spring after all danger of frost has passed. In the garden, they prefer shade and a rich, moist soil. After blooming, when the leaves begin to yellow, the plants should be rested by gradually reducing water, allowing them to dry out.
