Calla lilies (Zantedeschia) are valued for their speckled leaves and unusual, cup-shaped flowers that come in a variety of colors. Two new varieties -- one with black flowers and one with white -- will add even more drama to your garden and container plantings.
'Edge of the Night' features rich, velvety, purple-black flowers. The white-speckled leaves have purple edges and stems. 'Edge of the Night' grows 2 feet tall and wide and is hardy in USDA zones 8 to 10.
In contrast, 'White Giant' (Zantedeschia aethiopica) grows a whopping 80 inches tall and features huge, white-speckled, lance-shaped leaves and 7-foot-tall, large, creamy white flowers. 'White Giant' is hardy in USDA zones 7 to 10.
Calla lilies grow best in full sun in the North and part shade in the South, on moist, well-drained soil. Keep soil cool by mulching. Tubers need to be dug and stored in cold areas.
