Scientific Name:
Pistia stratiotes

Family:
Water Lettuce

Family:
Araceae

Description:
Water Lettuce should not be used in non-freezing climates where it can become a noxious water pest. However, in constructed water gardens of the north, it functions as an ornamental floater...you won't notice any flowers. Its light green foliage forms rosettes, and the plants form large floating colonies in the tropics.
