About Calla Lilies
Calla lilies are not true lilies and belong to the genus Zantedeschia. Native to southern Africa, calla lillies are considered tender perennials in USDA zones 8 to 10. However, they can be grown as annuals or in containers, even as houseplants, throughout the rest of the country. Planted in spring, the flowers bloom for 6 to 12 weeks through the summer.
Beautiful trumpet-shaped blooms and long, sword-shaped foliage make calla lilies a favorite flower for weddings, borders, and colorful containers. The flower is made of a spathe and a spadix, like a caladium or jack-in-the-pulpit. The spathe is a modified leaf that curls around the spadix; that’s the spike-y thing in the center.
Calla lilies are available in many colors, including white, yellow, burgundy, near-black, rose, pink, orange, and multi-color varieties. They range from 1 to 3 feet tall, and typically one rhizome will spread out to about a foot in diameter.
