The meaning of calla lilies has changed through the years. Used as a flower to symbolize fertility and sexuality by the ancient Egyptians and Romans, respectively, calla lilies are now associated with marital bliss and true devotion between spouses.
Moreover, white calla lilies symbolize rebirth and resurrection, which is why we often see these flowers used in Easter services and funeral arrangements. Yellow calla lilies symbolize gratitude, pink for admiration, and purple for passion. Black calla lilies are also known to express elegance and mystery.
