People grow it for its unusual and intriguing appearance in woodland gardens or naturalized areas. Attempting to grow it indoors is challenging due to its specific environmental needs.
Water Lily
Nymphaea spp.
Water lilies are aquatic rhizomatous perennials known for their striking, floating leaves and beautiful, often fragrant flowers.
