We have almost no 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. It is likely to require a sunny position in a dry to moist well-drained soil.
A latex obtained from the root is used as a chewing gum[
]. The skin of the root is used, the gum is obtained by pounding the roots[

Seed - we have no information on this species but suggest sowing the seed in late winter or early spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
