Blackthorn, Prunus spinosa, is a native deciduous, spiny shrub used traditionally to make a natural, informal hedge. It provides interest throughout the year, bearing flowers in spring and spherical, purple berries (sloes) in autumn.

If left unclipped, Prunus spinosa eventually develops into a small freestanding tree. It’s extremely valuable to wildlife: its leaves are used as a caterpillar foodplant for many species of moth, its spring flowers provide nectar and pollen for pollinators and its autumn berries feed birds and small mammals. What’s more, when clipped as a hedge, the dense mass of thorny stems makes the perfect nesting habitat for birds.
