Sorry, I started thinking about things floating or not and my mind went to Monty Python and the Holy Grail. Try these for things that float,... or don't. http://www.3dcafe.com/asp/meshes.asp Hundreds of everything http://3dplants.0catch.com/index.html They have water plants including cattails and lillypads. Hope these are more help than my last smart alec remark.
