Blackthorn

British native · Hedgerow Shrub

Blackthorn is a thorny British native hedgerow shrub, famous for its masses of small white blossom appearing on bare branches in very early spring. Dark, dense stems form an excellent boundary or thicket, followed later by blue-black fruits. It is a powerful wildlife plant for larger gardens and mixed native hedges.

Why grow it

Its blossom arrives at a crucially early point in the year, supporting insects before many other shrubs have opened. Blackthorn also creates exceptionally secure cover for nesting birds and a dense backdrop for a varied hedge. It is a good choice where you want an informal boundary that offers flowers, fruit and shelter across several seasons.

How to grow it

Plant Blackthorn in sun or partial shade, in ordinary, well-drained soil, during the dormant season if buying bare-root stock. Space plants 45 to 60 cm apart for a hedge and water carefully through their first growing year. It is robust on many soils but can send up suckers, so allow room or remove unwanted shoots while young. Prune after flowering or in late summer, wearing gloves and keeping clear access paths away from its thorns.

Wildlife value

Early blossom provides nectar and pollen for bumblebees, honeybees, solitary bees and hoverflies. Blackthorn leaves support the caterpillars of many moth species, while its dense, thorny habit helps protect nesting birds. The later fruits are used by birds including blackbirds and thrushes, and the thicket offers dependable cover in winter.

Tips

Use Blackthorn where its suckering habit and sharp thorns can be accommodated, rather than beside a narrow path. A mixed hedge prevents it becoming visually heavy. Buy UK native-origin stock from reputable suppliers and never take suckers, plants or seed from wild hedgerows.
