Wood Sorrel (Oxalis acetosella)

Common Names:

Wood Sorrel, Fairy Bells, Wood Sour, Cuckoo's Meat.

​

Season:

Spring, Summer, Autumn, Winter.

​

Identification:

Wood Sorrel is found in established woodlands, presenting three heart-shaped leaves with a perpendicular stem, similar to clover. The leaves close at night or in harsh conditions. Delicate white flowers with pink or purple veining bloom, and the thin, green to red stem is the tastiest part.

​

Habitat:

Wood Sorrel is found in the UK, most of Europe (specifically Northern), Northern America, and most of Asia. It thrives in damp woodlands, growing in clumps with heart-shaped leaves from 5-10 cm in length.

​

Possible Confusion:

May be mistaken for clover, but the distinctive heart-shaped leaves and citrus/apple peel taste set it apart. Various Oxalis family members are edible, including Pink-sorrel and yellow-flowered species. A purple variety called Creeping Wood Sorrel is known to accumulate copper.

​

Food Uses:

Wood Sorrel is edible, and its oxalic acid content gives it a sour taste. It's rich in Vitamin C and historically used to treat scurvy.

Leaves can be used in salads, sauces, smoothies, juiced, cakes, and icing. Flowers are also edible and can be used in various culinary applications.

Oxalic acid can be toxic in large quantities, but it's generally safe when eaten moderately with a varied diet.

​

Medicinal Uses:

Historically used for treating scurvy due to its high Vitamin C content. Used by American Indians for cramps, nausea, fever, and soreness. Contains oxalic acid, but in moderation, it has been used to calm stomach upsets.

​

Other Facts:

The name "Sorrel" comes from the French word for sour. All Oxalis family members contain oxalic acid, and while it should not be eaten in large quantities, its presence is comparable to foods like chocolate, coffee, and pulses.
