The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

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 most parts of this country. The following notes are based on the general needs of the genus. Easily grown in a well-drained loam, preferring a position in full sun but tolerating shade. Prefers an alkaline soil but tolerates a slightly acid soil. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – sow early spring or autumn in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Edible Uses:
Young shoots and leaves – cooked. A famine food, it is only used when all else fails.

Medicinal Uses:
The plant is rich in tannins. It is astringent and is used in the treatment of diarrhoea. It is also emmenagogue and febrifuge. It is used in Korea to treat fevers and as a women’s tonic. The plant has antitumour activity
