Rumex acetosella, commonly known as red sorrel or sheep’s sorrel, is a perennial herb that is native to a variety of habitats across Eurasia and the British Isles, including open woodlands, grasslands, and heathlands. It is particularly well-adapted to acidic, sandy soils and often colonizes disturbed areas. The plant typically grows to a height of 18 inches (45 cm) and has a spreading habit due to its rhizomatous root system. It features distinctive green, arrowhead-shaped leaves and red-tinted stems, with small maroon female flowers that appear in early summer. The flowers are not particularly showy but are interesting upon close inspection.

Red sorrel is valued for its culinary uses, as the leaves have a tart, lemony flavor and can be used in salads or as a garnish. It is also used in traditional medicine for its potential health benefits. In cultivation, it requires minimal care, thriving in full sun to part shade and tolerating a range of soil types, though it prefers well-drained, sandy soils. While it can be an attractive addition to herb gardens, it is important to manage its spread to prevent it from becoming invasive. Gardeners should be aware that Rumex acetosella contains oxalates, which can be toxic to livestock in large quantities. It is also potentially invasive in some regions outside its native range, so it is advisable to check local regulations before planting.CC BY-SA 4.0
