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 many parts of this country. Judging by the plants native habitat it is likely to require a well-drained light to medium soil in a sunny position. It is also likely to be resistant to maritime exposure.
Propagation
Seed - we have no details for this species but suggest sowing it as soon as it is ripe in a cold frame. Alternatively, sow stored seed in late winter in a cold frame. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
