Horse chestnut  (Aesculus hippocastanum)

Horse chestnuts are a native of Greece and the Balkans, but have been introduced to many temperate countries around the world. In the UK, it occurs virtually everywhere except the Scottish Grampian regions and the extreme northwest mainland and islands.

As an introduced species, horse chestnut can be found in parks, large gardens and estates, but it also occurs in the wild as a naturalised tree on various habitat types, ranging from damp fens and woods to upland road verges.
