Seeds, which are rolled up in a ball of clay and dropped into a pond, or sown in pots which are then submerged in shallow water, either in-doors or out. Usually increased by portions of the root-stocks, which are sunk in the pond and held by stones, or the tender species placed inside, in pans of water. Some species produce tubers on the root-stocks, which are used for propagation.
