Cultivation Details
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of the country. This plant does not appear in The Flora of China[1], and so its stated distribution needs to be questioned[PFAF]. The following notes are based on the general needs of the genus. A pond or bog garden plant, it requires a moist or wet loamy soil in a sunny position[2, 3]. It can also be grown in shallow, still or slowly flowing water. The flowers of species in this genus are either polygamous or monoecious. They are produced in whorls of three with a male flower at the top and two hermaphrodite or female flowers at the bottom[1].
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.
