Blackthorn Overview

Prunus spinosa is a small, thorny, deciduous tree species commonly known as Blackthorn. Its from the rose family, Rosaceae and it produces oval-shaped, dark green foliage and pretty white flowers early in the spring. Flowers measure around 1.5cm across, they have 5 petals coloured white and the flowers form before the leaves. Flowers lead onto blue-black drupe fruits known commonly as sloes, these measure approximately 1-1.2cm across and they are covered in a waxy substance. They ripen during the autumn and are commonly harvested in October-November in the UK. This species is part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants which support pollinator populations by providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!
