Water callas (Zantedeschia aethiopica) are captivating aquatic perennials renowned for their striking trumpet-shaped flowers that emerge from dramatic arrow-shaped foliage. While they are often associated with wetlands and ponds, these versatile plants can thrive in various environments, adding a touch of elegance to gardens, balconies, and even indoors.

Cultivation and Care

Sunlight and Temperature:

• When growing in containers, use a potting mix specifically formulated for aquatic plants.

Fertilization:

• Fertilize lightly every 2-3 weeks during the growing season with a balanced liquid fertilizer.
• Avoid over-fertilizing, as this can burn the roots.
