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 the country. It requires a well-drained soil and should succeed in sun or shade. A fully parasitic plant lacking in chlorophyll, it is entirely dependant upon its host plant for obtaining nutrient. The correct name for this species is Boschniakia hookeri.
Propagating it: Seed - we have no information on this species but suggest sowing the seed in a greenhouse in a pot containing a host plant. The seed is probably best sown as soon as it is ripe if this is possible. It might also be possible to sow the seed in situ around a host plant.
