Does anyone recognize this plant? It's growing in fresh water behind a neighbors house across from my backyard. I zoomed as close as I could get and cropped a couple of pictures for (hopefully) a better view. I've lived here four years and never noticed blooms but it may just be that I missed them cause I don't often pay much attention to that particular area. These plants seem to be @ 3 feet above the water line ... water level is probably about 1 foot right there.
