The horse chestnut tree (scientific name Aesculus hippocastanum) is cultivated worldwide in temperate environments. The horse chestnut tree is common in parks and gardens because of its size, elegant domed shape and showy white flowers. The tree's name, horse chestnut, reflects in part the tree's fruit, which has a chestnut-like appearance although it is not a nut. You can identify a horse chestnut tree by its several defining physical characteristics.

Horse chestnut tree with rounded, domed crown.

Observe the shape. Mature horse chestnut trees range from 40 to 60 feet tall and have a rounded or domed crown.

Horse chestnut tree leaves and flowers.

Examine the leaves. Horse chestnut tree leaves may be four to six inches long and range from a pale green below to a darker green above. The leaves are palmate and typically have seven leaflets.

Horse chestnut tree bark.

Examine the bark. Look for rough, irregular ridges and a scaly texture with colouring from light to dark brownish grey.

Examine the flowers. In spring, when the flowers appear, they grow upright five to eight inches tall. The flowers are white, showy and may have small reddish spots.

Horse chestnut tree fruit.

Examine the fruit. The horse chestnut tree fruit has a green, spiky epidermis containing one to three glossy brown seeds called conkers.
