Nodding to its common name, duckweed is a beloved food for ducks and also for turtles, goldfish, tilapia, carp, and koi fish. Native to much of North America, duckweed grows atop ponds, surviving winters in USDA plant zones 4 through 10. Adaptable to a wide range of temperatures, it can also be grown easily outdoors on home ponds and indoors, near a sunny window, in large aquariums. Duckweed is native to North America and Central America, Asia, Africa, and Europe. Plants have also been introduced into Australia and South America.
