Pistils stratiotes (water lettuce)

Water lettuce pond plants are commonly found in the slow-moving waters of drainage ditches, ponds, lakes, and canals in water anywhere from 0 to 30 feet (0-9 m.) deep. Its early origins were recorded to be the Nile River, possibly around Lake Victoria. Today, it is found throughout the tropics and the American Southwest with no wildlife or human food uses for water lettuce recorded. It can, however, make an attractive water feature planting where its rapid growth may be corralled.
