AESCULUS

These big, bold plants have an almost tropical look. The leaves are divided fanwise into large, toothed leaflets. Showy spring flowers, borne at ends of branches in long, dense clusters, attract hummingbirds. In autumn, leathery fruit capsules enclose glossy seeds. Prune established horsechestnuts only to eliminate dead or damaged wood and any awkward-looking branches.

Aesculus x carnea

This tree is a hybrid between A. hippocastanum and A. pavia. Grows to 40 ft. tall and 30 ft. wide—smaller than A. hippocastanum and a better fit for small gardens. The tree is round headed, with large dark green leaves, each divided into five leaflets; a mature tree casts dense shade. Flowers with a profusion of 8-in.-long plumes of soft pink to red flowers. ‘Briotii’ has rosy crimson blossoms, ‘Fort McNair’ has pink flowers with yellow throats, and ‘O’Neill Red’ has single flowers of bright red.
