Anbody know of a good hybrid lily that won't spread to the deeper areas of the pond and take over? Something that will stay 4' or less. Looking for something attactive to me and the fish to put in a new pond. Something that might take space and sunlight from the pain in the &*$ cattails and bind nutrients away from the inevitable Chara onslaught \:\( . The pond is very clear right now and dug down into the water bearing sand to maximum depth of about 14' deep. Slopes off rapidly in some places but other places will be the scene of a constant cattail battleground if I don't get something started that will shade them out or out compete with them (maybe it's impossible or impractical? ; cattails are REALLY a bad problem in the sandy soil area where my pond is located, they take over ponds quickly). Also, being entirely fed by groundwater, my 3/4 acre pond is very clear (not crystal clear; still some suspended minerals from the sand that give the water a slightly blueish cast). You can easily make out the bottom at 6' and like most other ponds in my area I suspect chara will be a problem. Although keeping cattle out of the pond area should help with the weed problem somewhat by limiting the amount of biomatter deposited into the pond area.

Anyone have any ideas? I know that lilies can be a worse headache than chara or cattails, but I am wondering if there are any hybrids out there that don't spread to deeper water and might help me combat pesky cattails and nasty chara but still provide me some fish habitat in the shallows.
