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. Requires a deep rich slightly acidic soil. A greedy plant, inhibiting the growth of nearby plants, especially legumes.
Propagation
Seed - best sown as soon as it is ripe in a cold frame in late summer. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a tray of water in a cold frame until they are at least 15cm tall. Plant them out into their permanent positions in the summer. Division in early spring or autumn. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the summer or following spring.
Edible uses
Young leaves - cooked. Some caution is advised, see the notes above on toxicity.
Habitat
Grasslands, by streams at elevations of 3200 - 4100 metres in SE Xizang and NW Yunnan.
Native range
E. Asia - China, Korea.
