Day flowering water lilies of the tropical type are the most popular subjects.
In addition to lilies, aquatic gardeners might use plants such as Arrowhead, Bulrushes and Water-hyacinths in the decoration of large pools so as to give a more natural setting. These plants are native in this region, being found in numerous canals and drainage ditches. These plants form excellent fish havens. This plant may become a pest. This delicate little plant, with its numerous small, roundish, floating leaves and small, yellow, poppy-like flowers is an addition to any shallow pool.
