Wood Sorrel (Oxalis acetosella) is a delicate and attractive plant of shady woodland, banks and other damp places, and is widespread in Cumbria. It is particularly characteristic of the county’s older, moss-rich woodlands, where it can form extensive patches beneath the trees.

The distinctive three-part, clover-like leaves are accompanied in spring by beautiful white flowers delicately veined with lilac or purple, usually appearing from April into May. Both the leaves and flowers respond to changing light levels, folding down in dull weather and at night.

Wood Sorrel thrives in the cool, moist conditions found in many Cumbrian woods and is often seen growing amongst mosses, ferns and Bluebells. Although easily overlooked when not flowering, in spring its fresh green leaves and white flowers can produce attractive carpets across the woodland floor.
