Plants are usually monoecious but dioecious forms are sometimes found[43]. A very polymorphic species[43]. In mud or shallow water the leaves are broad, but in deep water the plant only produces long slender leafstalks[212]. This plant has potential for commercial cultivation as a root crop[212].

Propagation

Seed - best sown as soon as it is ripe in a pot standing in about 5cm of water. Prick out the seedlings into individual pots when they are large enough to handle, and gradually increase the depth of water as the plants grow until it is about 5cm above the top of the pot. Plant out in late spring or early summer of the following year. Division of the tubers in spring or autumn. Easy. Runners potted up at any time in the growing season.
