Your eye is going to be drawn to the yellow waterlily, but it is really the small green spheres covering the water that I am going to talk about. That tiny plant is called Duckweed (Lenticule). They float on the surface of still water, sometimes covering it entirely and making the pond appear green.
If you could look at them closely, you would see that the free floating leaf is similar to a lily pad, and each pad has a thread-like root that dangles down in the water for nutrients. I took this photo at McBride’s Horseshoe Lake.
