Horse Chestnut - Aesculus Hippocastaum L. - Maple Family
Placed by some in the Soapberry Family, or Sapindaceae, and by others in the Hippocastanaceae Family. I have seen them in both Montpelier and Burlington, Vermont, probably planted. Aesculus hippocastanum is a large deciduous tree, commonly known as Horse-chestnut or Conker tree.
It is native to a small area in the mountains of the Balkans in southeast Europe, in small areas in northern Greece, Albania, the Republic of Macedonia, Serbia, and Bulgaria. It is widely cultivated throughout the temperate world.
