Assuming you mean the long leggy plants in the centre of the photos, they are not Echinodorus (swords) or Cryptocoryne. No species in either genus grows leaves off a stem in this manner. As to what they are, I've no idea, I've never seen something like this. I would have to dig through my reference works, so hopefully someone who knows can comment first.
Another thing I know of this plant it is a native or at least is found in Tennessee. I found it a lake where I go swimming all the time. The plant grows from a center point and sends off runners. The leaves will reach the surface and float on top. I have it planted in a tank with only plants right now to see if I can get it grow.
It might be quicker to do a serach of native plants. The US Dept of Agriculture has information, not sure how it is organized (by state, or whatever) but I have come across their site now and then as some of our "tropical" aquarium plants are invading NA.
Is it red on the bottom or slimy? Could it be Watershield? You said it lays on the top of the water - NOT pokes up? It reminds me of Pickerel rushes, but they don't lay flat. . . any idea if it gets a flower? I have no idea! Good luck, though!
It has a stem that has a root system in the dirt. The leaves grow up from the stems and reach the surface. No idea if it has a flower never seen one but doesn't mean it doesn't. Posted via Mobile Device
I bet it's just some sort of generic pondweed, honestly. American Pondweed - Potamogeton. . . whatever. There are tons of different varieties of it, and it can be found nearly everywhere. Look in that direction and you may find what you're looking for
Thanks Ches! It looks very much like Long-leaf Pondweed (Potamogeton nodosus). I am hoping I can get it to take off. As I would love to see it form a mat on the surface of my tank!
Yay! Glad I could help, and I hope you got your answer. It'd be awesome if you could get it to cover - even if that were the only thing in the tank - that would be a pretty cool effect. . . nice cover from above and all of those long stems beneath. *nods* Let me know how it does
Yeah it would be awesome if I could get that look which is what I am hoping for! If it does die no big deal since it didn't cost me anything. I will keep ya updated. Posted via Mobile Device
