An uncommon hedgerow and woodland tree of central and eastern England, Purging buckthorn displays yellow-green flowers in spring, and poisonous, black berries in autumn.
Purging buckthorn, sometimes simply called 'Buckthorn', is a small, spiny tree of woodland, scrub and hedgerows on chalky soils. It is widespread, but scarce, across lowland areas of central and eastern England. Clusters of small, yellow-green flowers appear in late spring, and bunches of poisonous, black berries ripen in autumn. Purging buckthorn is the main foodplant of the Brimstone butterfly in the areas where it grows, but Alder buckthorn is used as an alternative.

Purging buckthorn is a small, spiny shrub. It displays oval, finely toothed leaves and clusters of black berries.

Did you know?
Purging buckthorn is so-named because its berries are a strong laxative ('purgative') for humans; they can also irritate the skin.
