Buckler-leaved sorrel (Rumex scutatus)

Rumex scutatus, often referred to as French sorrel, buckler-leaved sorrel, or shield-leaf sorrel, is a notable herb in the culinary world. It is prized for its tangy, lemon-like flavor, which is attributed to its oxalic acid content. While it is often used in a variety of dishes, including soups, sauces, and salads, its distinctive sharp taste makes it a favorite for enhancing the flavor of fish and poultry. This hardy plant can withstand frost and short dry periods, growing quickly into a sizable clump with broad leaves that can reach up to 10 centimeters (4 inches) in width. French sorrel is sometimes preferred over garden sorrel (Rumex acetosa) for its culinary applications.
