How to Grow
We do not have much 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 at least in the milder parts of this country. The following notes are based on the general needs of the genus. Prefers a fertile humus rich moisture-retentive well-drained soil in cool shade or semi-shade. Plants are intolerant of heat and drought but they tolerate most other conditions. Members of this genus are rarely if ever troubled by browsing deer or rabbits. The young shoots are very attractive to slugs. Hybridizes with other members of this genus.
Propagation: Seed is best sown as soon as it is ripe in early autumn in a shady part of a cold greenhouse. Stored seed should be sown as early in the year as possible. Germination can be slow, seedlings may not come true to type, and it takes several years for plants to reach a good size. When large enough to handle, prick seedlings out into individual pots and grow on in a shady position in the greenhouse for at least the first winter. Plant out into permanent positions in late spring or early summer, after the last expected frosts. Division can be done in March or October. Larger divisions can go directly into permanent positions, while smaller divisions are better potted up and grown on in light shade in a cold frame until well established before planting out in late spring or early summer.
Medicinal Uses
The roots are antiperiodic, antirheumatic, demulcent, refrigerant, sedative, sialagogue, and tonic.
Other Uses
