Red horse-chestnut - Aesculus × carnea

"Aesculus" × "carnea" is an artificial hybrid between "A. pavia" and "A. hippocastanum". 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".
