Aesculus x carnea ‘O’Neill Red’

Red Horsechestnut
Sapindaceae
Deciduous, Trees

AESCULUS

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.
