The Calla flower, also known as the Arum LILY, is a species of flowering plant native to South Africa. It is a popular ornamental flower, and its white spathe and yellow spadix are often used in floral arrangements. The Calla flower is also known by its scientific name, Zantedeschia aethiopica. The term 'Calla LILY' is actually a misnomer, as it is not a true LILY. However, it is commonly referred to as such due to its resemblance to the LILY family.
