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 much of the country. This species has 24 chromosomes which makes it quite distinct from P. ginseng which has 44 chromosomes[174]. The following notes are based on the general needs of the genus. Requires a moist humus rich soil in a shady position in a woodland[200].

Plant Propagation
Seed - sow in a shady position in a cold frame preferably as soon as it is ripe, otherwise as soon as the seed is obtained. It can be very slow and erratic to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a shady position in the greenhouse or frame for at least their first winter. Make sure the pots are deep enough to accommodate the roots. Plant out into their permanent positions in late summer. Division in spring.
