''Aesculus'' × ''carnea'', or red horse-chestnut, is an artificial hybrid between ''A. pavia'' (red buckeye) and ''A. hippocastanum'' (horse-chestnut). The origin of the tree is not known, but it probably first appeared in Germany before 1820. The hybrid is a medium-size tree to 20–25 m tall, intermediate between the parent species in most respects, but inheriting the red flower color from ''A. pavia''. It is a popular tree in large gardens and parks. ==Cultivars== * 'Briotii' (named in 1858 to honor Pierre Louis Briot, the nurseryman at Trianon-Versailles near Paris, France) This is the most commonly seen cultivar which has 10-inch tall, deep rosy flowers and matures as a smaller tree.〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=70 )〕 * 'O'Neil', which produce larger (10-12 inch) panicles with brighter red flowers. * 'Fort McNair' (named from where it was selected) it has dark pink flowers with yellow throats and resists leaf scorch and leaf blotch. * 'Pendula' with arching branches.〔Govaerts, R., Michielsen, K. & Jablonski, E. (2011). Untraced Weeping Broadleaf cultivars: an overview. ''(Belgische Dendrologie Belge )'' 2009: 19-30.〕 * 'Plantierensis' which has intense rose pink flowers with yellow throats and does not set fruit, which makes it less messy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aesculus × carnea」の詳細全文を読む スポンサード リンク
