Nymphaea mexicana is perhaps best known as a noxious weed in wetlands outside of its native range, such as California. It can easily invade similar aquatic ecosystems when it is introduced. The plant is attractive and has been introduced to new habitats for ornamental purposes.[citation needed]
Nymphaea mexicana has thick rhizomes and long, spongy creeping stolons which bear bunches of small yellow roots that resemble miniature bananas. The plant can grow from seedlings or send out new shoots from its stolons. The large, flat leaves are green with purple or brown patterning, and float on the surface of the water. The floating lotus flowers have yellow petals and pointed, star-like, greenish-yellow sepals. The flowers close at night.[5]

The plant flowers during the summer, and also during spring and fall in warmer areas. Seeds are contained in green berries which grow underwater. It grows in marshes and readily invades canals and other shallow waterways, sometimes becoming a nuisance.
It was published by Joseph Gerhard Zuccarini in 1832.[2]
The chromosome count is n = 28. The genome size is 586.80 Mb.[6]
Nymphaea mexicana reproduces vegetatively through stolons. Their structure, resembling bananas, consists of leaf buds and thick, starchy roots.[7]
The NatureServe conservation status is Vulnerable (G3).[1]
The canvasback duck, Aythya valisineria, feeds on the banana-like roots of the plant.[8]
