Origins and History
Zantedeschia kalla originated in the wetlands of South Africa, where it thrived in the moist, shady conditions.

Botanical Description
Tubular Bract
The calla lily’s most striking feature is its tubular bract, which resembles a trumpet or funnel. This modified leaf is what most people perceive as the flower. It can range in size from miniature to grand, and its colors vary from pure white to vibrant hues such as yellow, pink, orange, and purple.
Spathe
Within the tubular bract lies the true flower of the calla lily, called the spathe. It’s a small, club-shaped structure that produces tiny, bisexual flowers. These inconspicuous flowers are responsible for pollination and seed production.
