Since some of you have Aquariums, I will share information on Aquarium plants native to America. Hornwort or coontail found in lakes. I bought a start and the collected some for my outdoor tubs as I needed a lot. Discovered Elodia floating in the lake but not much. I noticed a plant growing on the bottom along the dock and thought that looks like the Guppy grass I bought. Looked up its native range and sure enough that is what it is.
