Blackthorn is a deciduous shrub or small tree, scientifically known as Prunus spinosa. It typically grows up to 3 meters tall and is characterized by its thorny branches and white flowers that bloom in early spring. The plant produces small, dark blue fruits called sloe, which are often used to make jams, jellies, and alcoholic beverages like sloe gin. This plant is commonly found in hedgerows and woodlands across Europe and parts of Asia. Blackthorn is also known for its dense growth, making it an effective natural barrier. Its wood is hard and durable, often used for making walking sticks and other tools.
