USDA Symbol: OXST

USDA Native Status: L48 (N), CAN (I)

A low spreading plant with clover-like, sour-tasting leaves and 1 to several yellow flowers.

With their clover-like leaves, the wood sorrels are easy to recognize. The sour taste of the leaves is distinctive and they may be used in salads, but sparingly, because of the oxalic acid content. The genus name comes from the Greek oxys ("sour"). This species is a cosmopolitan weed, perhaps originally native to North America. It is especially common as a garden weed. The very similar Slender Yellow Wood Sorrel (O. dillenii), has seed capsules on reflexed stalks. Large Yellow Wood Sorrel (O. grandis) has flowers to 1" (2.5 cm) wide and leaves often with purple edges; it is native and grows from Indiana east to Pennsylvania and south to Georgia and Louisiana.

Benefit

Use Food: EDIBLE PARTS: Small amounts of leaves, flowers, seeds, tubers/roots eaten raw are not dangerous. Gather stems and leaves during early spring through fall. Tender stems and leaves can be steeped in hot water. Use liquid as a sour lemonade-type drink. For tea, use a handful of leaves per pint of water. Add to salads for a lemony taste. Cook with greens to enhance mild flavors. Remove stems if too stringy. Use flowers raw in salads or as cooked greens. Add young seed pods to salads or cook with the leaves and stems. Clean tubers and roots and eat raw or cooked with the greens, seeds, and flowers. (Poisonous Plants of N.C.)


Warning: POISONOUS PARTS: All parts. Low toxicity if ingested (no documented cases in humans). Symptoms in grazing animals, when eaten in large quantities, may cause trembling, cramps, and staggering as in grazing animals. Toxic Principle: Soluble oxalate.
Deer Resistant: High
