description_en: Genus of about 15 species of deciduous trees and shrubs, mainly from woodland in S.E. Europe, the Himalayas, E. Asia, and North America. They have opposite, palmate leaves, mostly mid- to dark green, some turning deep yellow or red in autumn. Large, upright, conical to cylindrical panicles of 4- or 5-petalled flowers, each 1.5-3cm (1/2-1 1/4in) across, with prominent stamens, are borne usually in late spring and early summer. The spiny or smooth-skinned, rounded to pear-shaped fruits contain 1 or 2 large, usually brown or blackish brown seeds. Most horse chestnuts are suitable only for large gardens, where they are best planted as specimen trees, although A. x mutabilis ’Induta’ and A. parviflora may be grown in a medium-sized garden. All parts may cause mild stomach upset if ingested.

hardiness_en: Most are fully hardy. A. californica and A. indica will be damaged below -15°C (5°F).
