Nymphae, commonly known as water lilies, are aquatic plants belonging to the family Nymphaeaceae. They are characterized by their large, flat leaves that float on the water's surface and their beautiful, often fragrant flowers that bloom above the water. These plants thrive in freshwater environments, such as ponds and lakes, and play a vital role in their ecosystems by providing habitat and food for various aquatic organisms. The flowers of Nymphae can be white, pink, yellow, or blue, depending on the species. They typically open during the day and close at night, a behavior known as nyctinasty. Nymphae are also important for water quality, as they help reduce algae growth and provide oxygen through photosynthesis.
