Calla lilies are not true lilies, but are arum (jack-in-the-pulpit) family members. They are stemless plants whose flowers and leaves rise directly from rhizomes. ëRubylite Pink Ice is a hybrid variety that typically grows to only 12-15î tall. Each flower features a yellow finger-like spadix that is surrounded by a showy light pink spathe born atop a leafless stalk. Blooms throughout summer.

Winter hardy to USDA Zone 9-10. Plant rhizomes in spring after threat of frost has passed. Best in moist to wet soils with part shade. Tolerates full sun in some climates, but prefers part shade in the St. Louis area. Lift rhizomes in fall and store in a damp medium such as peat or immediately replant in containers to overwinter as a houseplant. Calla lilies may be planted in shallow water in mud at the edge of ponds or water gardens. In this case, the rhizomes could arguably survive a St. Louis winter if the covering water does not freeze to the bottom. May also be grown year round in containers that must be brought indoors in winter before first frost. Overwintering containers placed near a window with bright indirect light can make attractive houseplants.
