Common sorrel or garden sorrel (Rumex acetosa), often simply called sorrel, is a perennial herb in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock. It is a common plant in grassland habitats and is cultivated as a garden herb or salad vegetable (pot herb).

[hide]Description[edit]
Sorrel is a slender herbaceous perennial plant about 60 centimetres (24 in) high, with roots that run deep into the ground, as well as juicy stems and edible, arrow-shaped (sagittate) leaves. The leaves, when consumed raw, have a sour taste. The lower leaves are 7 to 15 centimetres (2.8 to 5.9 in) in length with long petioles and a membranous ocrea formed of fused, sheathing stipules. The upper ones are sessile, and frequently become crimson. It has whorled spikes of reddish-green flowers, which bloom in early summer, becoming purplish.[2][3] The species is dioecious, with stamens and pistils on different plants.[3]
The leaves are eaten by the larvae of several species of Lepidoptera (butterfly and moth) including the blood-vein moth.

Uses[edit]

The recipe varies according to different levels of household income.
