Wood sorrel

Wood Sorrel is a common name for several plants in the family Oxalidaceae. Some species are widely regarded as weeds, while others are often cultivated for their attractive flowers and foliage.

Description

Wood sorrels are small to medium-sized herbaceous plants, with most species in the 10–15 cm height range. They have a characteristic three-parted clover-like leaf, and a capsule fruit which scatters the seeds when ripe. Some species, such as the common wood sorrel (Oxalis acetosella), have an additional method of propagation via underground bulbs.

Distribution and habitat

Wood sorrels are found throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico and South Africa. Many species are adapted to woodland habitats, preferring a moist, shady environment; others prefer full sun.

Uses

Wood sorrels have been used for food and medicine by many Native American tribes, and in modern times, some species are cultivated as ornamental plants. The leaves of wood sorrels are quite edible, with a tangy taste of lemons. A tea made from leaves of certain species has been used in the treatment of fever, nausea, and stomach disorders.

Species

There are about 570 species of wood sorrels. Some of the more well-known include:

• Oxalis acetosella – common wood sorrel
