Calla lilies (Zantedeschia) are not hardy in colder climates and can be damaged by freezing temperatures. In regions where winter temperatures drop below freezing, it's best to dig up the tubers in the fall and store them in a cool, dry place until spring. In milder climates, they may survive the winter and bloom again, but in general, it's safer to lift and store them to ensure their health for the next season.
