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 this country. The following notes are based on the general needs of the genus. Succeeds in sun or shade in deep, moist, wet, lime-free soil that is rich in organic matter[200]. Grows well in a bog garden or along the wet banks of streams and ponds[1, 238]. All parts of the pant, but especially the flowers, have a strong unpleasant aroma[4, 187]. The plant can raise the temperature of its inflorescence by 15 - 35°c above the ambient air temperature, thus protecting itself from frost and helping to attract pollinating insects[200, 238].

Plant Propagation
Seed - best sown as soon as it is ripe in a cold frame[200]. The seed should be stored in water if it is not sown immediately[238]. Stored seeds can be sown in late winter or early spring. Stand the pot in 2cm of water to keep the compost wet. Germination should take place in the spring, prick out the seedlings into individual pots once they are large enough to handle and grow them on in wet soil in light shade in the greenhouse for at least their first winter. Plant them out in late spring once they are large enough. Division with great care whilst the plant is dormant[200].
