How it is grown
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 this country. A polymorphic species, it is closely related to C. hirsuta. The following notes are based on the general needs of the genus. Prefers a moist humus rich soil in shade or semi-shade but succeeds in most soils that are not dry.
