About Blackthorn
Prunus spinosa, commonly known as blackthorn or "slåpetorn", is a deciduous thorny shrub from the Rosaceae family, prized for its abundant white spring blossoms and small, dark fruits, the sloes. It forms impenetrable hedges and is ideal for wild gardens, property boundaries, or attracting wildlife. Its dense structure makes it an excellent natural barrier and a haven for birds.
Native range
Europe, Northwest Africa, and Western Asia
Care tips
Blackthorn is extremely hardy and tolerates a wide range of conditions, preferring full sun to partial shade and well-drained soils, though it's not particular about soil type. Once established, it is very drought-tolerant and requires little supplementary watering. Avoid frequent transplanting, as it can disturb its root system; it's best planted in its final location from the start. Exercise caution due to its sharp thorns when pruning or handling.
