General Description

Rose red horsechestnut is a hybrid between the European horsechestnut (Aesculus hippocastanum) and the red horsechestnut (Aesculus pavia). It is a medium to large, spreading deciduous tree with an oval to round crown and dark green, glossy, palmate leaves with five to seven leaflets, which produce little fall color. It is best known for its beautiful panicles bright rose-red flowers that appear from late spring to early summer. These are followed by large round, spiny capsules that contain two to three shiny, inedible brown nuts. Though it is a hybrid, they will grow true from seed.

This tree prefers full sun and well drained, average soil. When subjected to drought and high wind its leaves have a tendency to scorch. Plant it as a specimen or shade tree in the landscape.
