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 the country. The following notes are based on the general needs of the genus. Prefers a fairly heavy loam but succeeds in a sunny position in most soils that are well-drained. Grows well in heavy clay soils.
Propagation
Pre-soak the seed for 24 hours in warm water and then sow in situ in spring or autumn.
