The horse chestnut is a large deciduous tree whose flowers have both male and female parts. It is planted in parks and along streets in temperate countries around the world, and it is very common in the United Kingdom. It can grow up to about 30 meters (100 feet) tall, with a wide, rounded crown. Its shiny brown seeds are called conkers, and children in Britain have long played a game called conkers with them. Horse chestnut seeds are poisonous if eaten, so they should never be confused with edible sweet chestnuts.

History

The horse chestnut comes from the Balkans in southeastern Europe and was brought to western Europe in the 1500s, reaching Britain in the early 1600s. Despite its name, it is not closely related to the edible sweet Chestnut. One story says the name comes from Turkey, where people were said to feed the seeds to horses that were coughing or unwell. For centuries the tree has been used in traditional medicine and in other ways. Its bark has been used to make a yellow dye, and its soft wood has been used for things like boxes and packing cases.

Anatomy

Horse chestnut leaves are palmately compound, which means they are made of five to seven leaflets spreading out from one point, like the fingers of a hand. In spring, the tree produces large, upright clusters of white flowers with pink or yellow spots, shaped like candles or cones. The flowers turn into spiky green cases, each holding one or two shiny brown seeds. The seeds contain a substance called aescin, which scientists have studied for its effect on swelling.
