Zantedeschia is a genus in the family Araceae, native to southern Africa. The genus contains 8 species and numerous cultivars 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, commonly known as Calla Lilies. Zantedeschia is widely popular and a beautiful addition to any garden. These plants can be grown in beds, borders, containers, but also in water (Zantedeschia aethiopica).
The genus was named in honor of Giovanni Zantedeschi (1773-1846), a botanist from Italy.
The plant is commonly known as “Calla Lily”. The name, which comes from the Greek word “calla” (“beautiful”), is actually a misnomer because the plant is not a true lily. Carolus Linnaeus, a famous Swedish botanist, made an error naming the plant. But despite the fact it was corrected later, the common name is still in use and relevant today.
Zantedeschia symbolizes beauty, purity, holiness and faithfulness.
It is also a symbol of rebirth and resurrection.
