Plant Care
Planting:
Plant Callas in fall to early spring. The rhizomes should be planted 4 inches deep and at least 1 ft. apart from each other. Many species of Callas die back in the fall, but reappear in the spring. When dormant in the winter, they still need water, but not as much as during the growing season.
Plant Z. aethiopica (marginally aquatic species) in aquatic containers 10-12" across.

Perennials with tuberous rhizomes. Can take full sun, but only in cooler climates. Where summers are hot Callas need light shade especially in the afternoons.
Where temperatures drop below 50F (10C), grow in a warm greenhouse or as a houseplant. Can plant out in summer.
