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 most parts of the country. We do not know the plants cultivation needs.
Young leaves and young plant - raw or cooked[
The plant is antitussive and febrifuge[
]. It is also used in the treatment of boils and snakebites[
Seed - we have no information for this species but suggest sowing the seed in middle to late spring in situ. If you only have a small quantity of seed then it will probably be better to sow it in a cold frame in mid spring and plant out in late spring.
