Duckweed is one of the smallest flowering, free-floating, plants found around the world. Measuring just 1/16" to 1/4" in length, duckweed floats on the water surface in colonies not attached to the bottom. Duckweed floats wherever the wind or currents take it, absorbing nutrients from the leaf undersurface and a very fine root hanging from it.
Duckweed can have one leaf or up to three leaves, known as fronds, about the size of a pencil eraser head, with a single root hair.
