Plants that like pond water

I noticed that since the water tool has been introduced the plants and trees are all hydrophobic, well as far as pond water is concerned. I want to make my trees and plants sit in a pond, not just on the surface but in the pond itself. I know there must be a way to do this and I have looked at the tuning for the water plants but I can't see what I need to add. I have even looked at the Outrigger Canoe but they all just sit on the water surface. I know I could use the 'move objects on cheat' but I really don't like using it, it sucks. I want to be able to mimic real plants sitting close and in pond water. Am I aiming high or is there a bit of code that might do it?  

Moderators you can delete this thread I must have had a game glitch, today all the game trees are taking to water like ducks!
