In Britain, the return to school after the summer holidays is synonymous with conkers. Originally played with cobnuts or snail shells, the use of the horse chestnut in the popular children’s game was first recorded in 1848. Since 1965, the World Conker Championships have taken place every year in Oundle, Northamptonshire. Kew.org

The fruits of this tree vaguely resemble those of the (Sweet) Chestnut tree but they are not related. They develop in prickly cases, and are ripe in September and October – the ‘conker’ season.
