Cultivation
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 could succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Prefers a cool moist peaty soil in the bog, woodland garden or a sheltered border in semi-shade. Only plant out full sized tubers and mulch them with organic matter in the winter. Most species in this genus are dioecious, but they are sometimes monoecious and can also change sex from year to year.
Propagation
Seed - best sown as soon as it is ripe in a shady position in a cold frame. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least a coupe of years until the corms are more than 20mm in diameter. Plant out into their permanent positions whilst they are dormant. Division of tubers when the plant dies down in late summer.
Edible uses
Young leaves - cooked. Some caution is advised - see the notes above on toxicity.
