Rumex scutatus (syn. Rumex alpestris) is a plant in the buckwheat family, used as a culinary herb. Its common names include French sorrel,[2]buckler sorrel, shield-leaf sorrel, and sometimes the culinary name "green-sauce".[3]
As a culinary herb, it is used in salads, soups, and sauces (especially for fish).[4] French sorrel tastes tart from its oxalic acid content, with a hint of lemon.[5] Later in the season, it can be bitter.[6]
French sorrel is hardy in most regions, tolerating frost, full sun and short dry spells.[7] It grows quickly to a clump up to 1 m (3.3 ft) in diameter, with long leaves up to 10 cm (4 in) wide. It is sometimes preferred for culinary uses to Rumex acetosa, garden sorrel.[8]
