Aesculus x carnea, or red horse-chestnut, is a hybrid tree resulting from the cross between horse-chestnut and red buckeye that is commonly found in the nursery industry. It prefers moist, well-drained, acidic soils, but can grow in slightly alkaline soil. It is less susceptible to leaf blotch and mildew than horse-chestnut and red buckeye but is still prone to these diseases. Red horse-chestnut as a hybrid produces fewer nuts compared to other Aesculus species. They are difficult to transplant due to their taproot and may require additional irrigation to help it establish in more urban areas. A cultivar, the ruby horse-chestnut, has nearly absent seed pods that make them a better alternative in urban street plantings, while the more common cultivar is the Ft McNair 'Fort McNair' horsechesnut.
