Prunus spinosa

Prunus spinosa (also known as blackthorn or sloe) is a species of Prunus native to Europe, western Asia, and locally in northwest Africa. It is a deciduous shrub or small tree growing to 5 meters tall, with blackish bark and dense, stiff, spiny branches. The leaves are oval, 2–4.5 centimeters long and 1.2–2 centimeters broad. The flowers are 1.5 centimeters diameter, with five creamy-white petals; they are produced shortly before the leaves in early spring, and are hermaphroditic and insect-pollinated. The fruit, called a "sloe", is a drupe 10–12 millimeters in diameter, black with a purple-blue waxy bloom, ripening in autumn, and harvested in October or November for making sloe gin.
