Rumex longifolius - DC.

Common Name dooryard dock
Family Polygonaceae
USDA hardiness Coming soon
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[238].
Habitats By rivers, in ditches and in damp grassy places[17].
Range Europe, including Britain, from Scandanavia south and east to the Pyrenees, Caucasus and C. Asia.

The mature stalk has excellent fibres. The fibrous bark can be split of in similar manner as from nettles.
