Propagation

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 April and plant out in late spring.

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 should succeed outdoors in most parts of the country. We do not know the plants cultivation needs.
