Common sorrel is the lemony-tasting leafy plant cooks know simply as sorrel, used for centuries in European soups and sauces. Native to Europe and Asia, it was brought to North America, where it now grows as an introduced weed of fields and roadsides and is also planted in vegetable gardens. Male and female flowers grow on separate plants.

Appearance

Growth form
Perennial herb, usually about 2 ft (60 cm) tall, sometimes up to about 3.5 ft (110 cm).
Leaves
Lower leaves are 1½–6 in (4–15 cm) long on long stalks, with two backward-pointing lobes at the base like an arrowhead. Upper leaves lack stalks and often turn reddish.
Flowers
Small reddish-green flowers in spikes in early summer, turning purplish as they age. They are wind-pollinated.
Fruit
After flowering, three inner flower parts enlarge into papery wings around a small three-sided seed about 1/10 in (2–2.5 mm) long.

Look-alikes

Sheep sorrelRumex acetosella

Sheep sorrel is smaller, and its leaf base usually flares out sideways like a spearhead instead of pointing backward like an arrowhead. Its fruits and seeds are about half the size.

Why they get mixed upBoth are sour-tasting weeds with reddish flower spikes.

Curly dockRumex crispus

Curly dock is much taller, with flower stalks up to 5 ft (1.5 m), and its long leaves have wavy, curled edges. Common sorrel is smaller, and its lower leaves have arrowhead-shaped bases.

Why they get mixed upBoth are common weedy docks with similar flower spikes and winged fruits.

Where it lives

Preferred conditions
Grows in sunny, disturbed or mowed ground and tolerates poor soil.

Life cycle

Reproduction
Each plant is either male or female.

Cautions

Cautions
