General Description

Considered to have the largest and showiest of all horsechestnuts, Japanese horsechestnut's white blossoms in midsummer yield brown fruits with red-brown seeds; its fall leaf color is a brilliant yellow. A tall, spreading deciduous tree from Japan, this species is popular in China and is often confused with Aesculus chinensis. The dark sandy brown bark is relatively smooth.

The leaves of this horsechestnut get as large as a basketball. Each hand--like leaf is comprised of five to seven leaflets of medium green that have a torn edge and lighter green underside. In midsummer, later than other species, the branches tips bear upright clusters of small white flowers that have yellow and pink specks, attracting bees. The round, smooth-skinned fruits are first beige and turn dark brown before splitting open to reveal the red-brown chestnut seed. In autumn the foliage becomes a spectacular yellow.

Grow Japanese horsechestnut is full to partial sun in a fertile, moist and deep soil that has good drainage. This showy shade tree is lovely in park settings and campuses, or wherever deep soils and space allow its presence.
