Not very clear, was I? I like to throw plants like water celery into small containers of water like whiskey barrel water gardens and quarantine tanks because it helps stabilize the water and health of the system. It oxygenates, stabilizes the nutrient cycles, and provides habitat for small fish that I scatter around to control mosquitos. It grows fast both above and below the water line, but isn't so invasive that I can't rip it out as a small water garden matures.
