What to Eat

Edible parts: Leaves, Stem

The leaves can be eaten raw or 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 grows in sands near the sea. It is a mediterranean plant.

How to Identify

A low slender herb. It has a creeping rhizome. It keeps growing from year to year. The leaves are oval or sword shaped and can have lobes. The fruit valves are several times larger than the nut.

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. It is likely to tolerate maritime exposure. 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. Prick seedlings out into individual pots once large enough to handle, and plant out during summer. Plants can also be propagated by division in spring.

Medicinal Uses

None known

Other Uses

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