Any ideas are more than appreciated.
I water lettuce will not work planted, but try water cabbage (Samolus parviflorous)
It looks similiar and will grow submerged. Be careful, because floating water lettuce is also called water cabbage but will not work submerged. Make sure it's samolus.
Also, I've looked everywhere for somewhere selling this, and I can't even find a picture on the internet. Good luck finding it. It would be exactly what you're looking for though, I remember seing it in a book. :-/
-edit- I found a pic
