Blackthorn (Prunus spinosa) is a deciduous, berry-producing shrub or small tree that is known for its sharp spines or thorns. It belongs to the same genus (Prunus) as cherry, plum, peach, apricot and almond trees. P. spinosa is native to Europe, western Asia, and northwest Africa. P. spinosa is most commonly found in hedgerows and thickets, forming dense stands of thorns. It produces five-petaled white flowers and dark round bluish purple berries. Each berry contains a large stone with a single seed inside.
P. spinosa has a reputation for causing infections and tissue reactions in horses, due its sharp thorns. The resulting condition is referred to as blackthorn plant thorn synovitis.
