Duck weed is a nice cover for a small pond like the one in your photo, but if you have fish, they'll eat it right up. I think you may be able to grow a water lily in there aswell. Hornwort is a good underwater plant. In reality, there are all sorts of pond plants. It just depends on what you want.
I've had good luck with corkscrew rush so far. It's a neat plant--some of the foliage grows straight, and some of it grows in a corkscrew pattern. It just depends how much room you have in your pond.
My rush hasn't really done anything. I may need to repot it into something larger but it really hasn't grown since I bought it. I've got corkscrew and blue.
