Cultural information: To bad this plant is native to tropical regions because its a real beauty. The "Water Calla Lily" has large, bright green glossy leaves to 16" in length. During the summer it can produce large white spathe shaped flowers to 10" in length, with a yellow spadice.

Set pre-started plants in spring after all danger of frost has passed, at the ponds edge or directly in the pond utilizing baskets at a maximum depth of 10". When grown in a shady area the plant will elongate and reach the maximum specs listed above. "Water Calla Lily" flowers can be cut and used as a cut flower. If your lucky enough to have a greenhouse pond... move the plant indoors the first week of September... or before first frost. Remove any dead or dying foliage and flowers as it appears.
