Known Hazards:	Although no specific mention has been seen for this species, the leaves of some if not all members of this genus contain significant quantities of oxalic acid and should not be eaten in any quantity. Oxalic acid can lock up certain minerals in the body, especially calcium, leading to nutritional deficiency. The content of oxalic acid will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[238].

Perennial growing to 1.5m by 1m . It is hardy to zone 7. It is in flower from July to August, and the seeds ripen from August to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Wind. We rate it 3/5 for edibility and 2/5 for medicinal use.

The plant prefers medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Habitats and Possible Locations

Cultivated Beds.

Edible Uses

The root is astringent, carminative, depurative, diuretic, purgative and tonic[51, 91, 240]. Small doses act as an astringent tonic to the digestive system, whilst larger doses act as a mild laxative[232].

Cultivation details

Prefers a deep, fertile, moderately heavy, humus rich, moisture retentive, well-drained soil in sun or semi-shade. Grows well in heavy clay soils.
A very ornamental plant[1], it is hardy to about -15° c[200].
Plants have proved very difficult to grow in cultivation in Britain[187].
Plants in this genus seem to be immune to the predations of rabbits[233].
Hybridizes freely with other members of this genus[200].

Propagation

Seed - best sown in autumn in a shaded cold frame[200]. The seed can also be sown in spring in a cold frame. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse or cold frame for their first winter, planting them out in the spring.
Division in early spring or autumn[1, 111]. Divide up the rootstock with a sharp spade or knife, making sure that there is at least one growth bud on each division. 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.
