Cultivation details
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 the country. The following notes are based on the general needs of the genus. Succeeds in most soils[1] but prefers a rich loamy soil in full sun or partial shade with plenty of moisture in the growing season[200].
