Nymphaea mexicana, commonly known as Yellow Water Lily, is a free-floating, frost-tender aquatic perennial that is commonly used as an ornamental plant in water gardens. It produces rosettes of wedge-shaped, overlapping, fluted, velvety, soft green leaves covered with water-repellant hairs. Plants resemble small open heads of lettuce. Min 50cm depth of water required
Nymphaea mexicana has many common names such as Mexican Waterlily and Banana Water Lily. It is sometimes cultivated and has become a minor weed in wetlands outside of its native range, such as California.
