Zantedeschia is a genus in the family Araceae, native to southern Africa. The genus contains 8 species of herbaceous perennials, divided into two main types: hardier outdoor forms with striking white flowers, called Arum Lilies, and the more tender forms with white-spotted leaves and colorful flowers, called Calla Lilies. Zantedeschia is a widely popular and a beautiful addition to any garden. They can be grown in beds, borders, containers and also in the water (Zantedeschia aethiopica).
The genus was named in honor of Giovanni Zantedeschi (1773-1846), a botanist from Italy.
Calla Lily, named after the Greek word “calla” (beautiful), is actually a misnomer because it’s not a true calla and it’s not a true lily. Carolus Linnaeus, a famous Swedish botanist, made an error naming the plant and even it was corrected after, the common name “Calla Lily” is still active and relevant today.
Zantedeschia symbolizes beauty, purity, holiness and faithfulness.
It is also a symbol of rebirth and resurrection.
