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. It probably does not have any special cultivation requirements and will probably succeed in most soils in a sunny position[K]. See also the records for C. stratum which might be a mis-spelling for this species.
