Nymphaea mexicana (Banana Waterlily or Yellow Waterlily) is a vibrant aquatic perennial native to Texas and the southern U.S., known for its sunny yellow blooms and lush, floating foliage. Often called Banana Lily due to its banana-shaped tubers, this striking water plant spreads across quiet ponds and ditches, with flowers that float or rise slightly above the surface. Blooming from spring to fall, it thrives in full sun and still water, making it a favorite in natural pondscapes and water gardens.
