Horse Chestnut Tree (Aesculus hippocastanum)

  • Broadleafed
  • Deciduous

The horse chestnut tree can grow to a height of more than 100 feet, but is typically shorter. The tree features prominent white flowers in spring. Ironically, the fruits from the tree (called “conkers” and not really chestnuts) are toxic to horses. Perhaps the most famous horse chestnut was the Anne Frank tree in Amsterdam, which, despite efforts by the Foundation Support Anne Frank Tree to save it three years earlier, was blown down in a windstorm in 2010.
