Honestly, the only aquarium plants that have really done semi decent outside in this pond is the Rotala. The other stuff just sort of does nothing. It doesnt die off, but it doesnt grow like crazy. The parrots feather is the nicest plant. I bought that at a local pond supply and garden center. I thought the aquarium plants would grow like mad but theyre not. Yesterday I moved the pond about a foot back more underneath the tree to give it a little less sunand more shade.
