Overview

Kew accepts Prunus spinosa in Rosaceae, native from Europe to Central Asia and Iran and in northwestern Africa, including Greece. Its 1753 publication is naming history only.

Blackthorn is a deciduous, densely branched shrub with suckers and thorn-tipped twigs. Alternate leaves are finely toothed. White flowers precede leaves; waxy purple fruit ripens blue-black around a stone. Botanically, it is a drupe.

It occupies scrub, forest edges, clearings and other woodland-grassland transitions. Early flowering provides resources for pollinators, and the thorny thickets offer shelter and nest sites. Hybridisation and cultivated relatives complicate its ancestry, and no parentage of domestic plums is asserted here.
