Thanks Bill. It looked like at the base it might be a rhizome type plant. The plant seemed to be jointed down towards the water line. I may dig up a plant tomorrow just to see what the roots look like.
This is the first year I have had much rooted plant growth around the pond. Water primrose has taken hold numerous places. Some rushes have started in places other than the places I planted them.
So next year may be a new chapter in pond management for me. Which could be a good or bad thing.
