Aesculus pavia

Red buckeye has hybridized with common horse-chestnut (Aesculus hippocastanum) in cultivation, the hybrid being named Aesculus × carnea, red horse-chestnut. The hybrid is a medium-sized tree to 13.5–17 m (45–55 ft) 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, most commonly the selected cultivar 'Briotii'. Hybrids of red buckeye with yellow buckeye (A. flava) have also been found, and named Aesculus × hybrida.
