Zantedeschia aethiopica, commonly known as white calla lily, is a perennial herb native to southern Africa, specifically found in the Cape Provinces, Free State, KwaZulu-Natal, Lesotho, Northern Provinces, and Swaziland. This plant thrives in wet environments and prefers full sun to partial shade, with soil that can be light (sandy), medium, or heavy (clay). It is hardy in zones 8-10 and grows up to one meter tall. Known for its ornamental value, the white calla lily features a large, showy spathe surrounding a central spadix, giving it a distinctive appearance. The plant's edible leaves are often used in cooking; they can be prepared fresh in salads or cooked as a green vegetable. However, it is important to remove the tough midrib before consumption. The white calla lily has been introduced into numerous regions including Albania, Algeria, Assam, Azores, Bermuda, Brazil Northeast, California, Canary Islands, Colombia, Corse, Costa Rica, Dominican Republic, East Aegean Islands, East Himalaya, Ecuador, Great Britain, Greece, Hawaii, India, Italy, Madeira, Mexico Southwest, Morocco, Mozambique, New South Wales, New Zealand North, Nicaragua, Norfolk Island, Oregon, Philippines, Portugal, Puerto Rico, Réunion, Sardegna, Sicilia, Society Islands, South Australia, Spain, St. Helena, Tasmania, Trinidad-Tobago, Tristan da Cunha, Tunisia, Turkey, Victoria, Western Australia, Yugoslavia, and Zimbabwe. This versatile plant not only adds beauty to gardens but also offers culinary benefits when used correctly. While it is primarily ornamental and edible, caution should be exercised if considering its use in traditional medicine or other applications, as no medicinal properties are currently documented.

Start with a simple, water-loving plant that thrives in full to partial sun and well-draining soil.
A Zantedeschia aethiopica plant or tubers, potting mix suitable for aquatic plants, a container with drainage holes.
Plant in spring when the soil is warm and there's no risk of frost.
Use a container that allows water to drain freely. Fill it with potting mix designed for aquatic plants, ensuring good drainage at the bottom.
Plant tubers just below the soil surface in the center of the container. Ensure they are not too deep or too shallow.
Keep the plant in a bright location but avoid direct sunlight for the first few days to prevent scorching. Water regularly, keeping the soil consistently moist.
Place the container in full sun or partial shade. Keep the soil moist and fertilize every 4-6 weeks with a balanced aquatic plant fertilizer.
Prune dead leaves to maintain the plant's appearance but avoid cutting back too much as it may affect growth.
