Commonly cultivated species and varieties of the well-known horse chestnut are among the most beautiful of spring and summer-flowering trees and make magnificent large round-headed specimens for a parkland setting. The American buckeyes, less spectacular in flower and variable in their garden value, make small shrubby trees. The following are particularly useful in smaller gardens.
Aesculus carnea briotii is a compact medium-sized variety of the red horse chestnut having deeper coloured, larger flower panicles. A. pavia atrosanguinea, the best-coloured form of the red buckeye, is an unusual small round-headed tree producing its deep redin June. All the chestnuts and buckeyes are trouble free and thrive in all well-drained soils.
