Garden sorrel
Rumex acetosa
A herbaceous perennial of the buckwheat family (Polygonaceae) grown as a culinary herb for its basal clusters of arrowhead-shaped leaves, which carry a tangy, acidic, sour-lemony flavor used in salads, soups, omelets, and sauces. Native to northern temperate regions, it reaches about 24 inches tall and sends up long, spike-like terminal clusters of greenish flowers that turn reddish with age in summer. Per the Missouri Botanical Garden PlantFinder, it self-seeds and spreads in the garden, and flowers should be removed promptly to keep new leaf growth coming; younger leaves taste best.
