Prunus spinosa, commonly known as the blackthorn or sloe, is a deciduous shrub native to Europe and parts of Asia. It typically grows between 1 to 3 meters tall and features thorny branches, small white flowers, and dark purple fruits called sloes. The plant thrives in hedgerows, woodlands, and scrublands, often forming dense thickets. The fruits of Prunus spinosa are known for their tart flavor and are often used to make jams, jellies, and alcoholic beverages like sloe gin. The shrub also provides important habitat for various wildlife species, contributing to biodiversity in its native regions.
