What to Eat

Edible parts: Leaves

The leaves are edible when cooked.

Known Hazards

Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content 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.

Where to Find It

It is a temperate plant. It grows between 400-2,800 m above sea level.

How to Identify

A perennial growing 1 m tall with hermaphroditic, wind-pollinated flowers blooming May to June and seeds maturing June to July. Adapts to light sandy, medium loamy, or heavy clay soils with well-drained conditions and mildly acidic to basic pH. Tolerates semi-shade to full sun and prefers moist to wet soil.

How to Grow

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 most soils but prefers a deep fertile moderately heavy soil that is humus-rich, moisture-retentive but well-drained and a position in full-sun or part shade.

Propagation: Sow seed in spring in a cold frame. Once seedlings are large enough to handle, prick them out into individual pots and plant out during summer. Can also be propagated by division in spring.

Medicinal Uses

None known.

Other Uses

No dye data specific to this species has been recorded, but roots of many plants in this genus yield dark green to brown and dark grey dyes without the need for a mordant.
