Aesculus (ancient name of some oak or mast-bearing tree). Including Pavia. Hippocastanaceae. HORSE-CHESTNUT. BUCKEYE. Trees or sometimes shrubs, cultivated for shade and for the conspicuous bloom of some species.
 +
 +
Winter-buds large with several pairs of outer scales: lvs. opposite, long-petioled, digitate, deciduous; lfts. 6-9, serrate: fls. symmetrical in terminal panicles; calyx campanulate to tubular, unequally 4-5-toothed; petals 4-5, with long claws; stamens 5-9; ovary 3-celled, with 2-ovuled cells: fr. a large 3-valved caps., usually with 1 or 2 large seeds; seeds large, brown, with a large pale hilum.—About 20 species in N. Amer., E. Asia, Himalayas and Balkan Peninsula. 
 +
 +
The buckeyes are deciduous trees and shrubs, with large, digitate leaves and red, white or yellow flowers in showy terminal panicles. They are cultivated for their showy flowers and handsome foliage, and some species make excellent shade trees. The large seeds are not edible.
 +
 +
Some species, as AE. Hippocastanum and AE. carnea are popular shade and street trees. They leaf early and soon give a dense shade. The shrubby species are well adapted for borders of larger groups or as solitary clumps on the lawn, particularly M. parviflora, with its slender panicles of white flowers; similar in habit and effect but with bright scarlet flowers, are AE. discolor, AE. georgiana and AE. splendens. Most of the species are hardy North, but the Californian and Himalayan species are suitable only for the southern states. They grow best in loamy and moist soil.
 +
 +
Propagation is by seeds to be sown in autumn or stratified, or by side-grafting and budding on common species, and the shrubby forms also by layers; AE. parviflora is propagated also by root-cuttings.

Aesculus (ancient name of some oak or mast-bearing tree). Including Pavia. Hippocastanaceae. HORSE-CHESTNUT. BUCKEYE. Trees or sometimes shrubs, cultivated for shade and for the conspicuous bloom of some species.

Winter-buds large with several pairs of outer scales: lvs. opposite, long-petioled, digitate, deciduous; lfts. 6-9, serrate: fls. symmetrical in terminal panicles; calyx campanulate to tubular, unequally 4-5-toothed; petals 4-5, with long claws; stamens 5-9; ovary 3-celled, with 2-ovuled cells: fr. a large 3-valved caps., usually with 1 or 2 large seeds; seeds large, brown, with a large pale hilum.—About 20 species in N. Amer., E. Asia, Himalayas and Balkan Peninsula.

The buckeyes are deciduous trees and shrubs, with large, digitate leaves and red, white or yellow flowers in showy terminal panicles. They are cultivated for their showy flowers and handsome foliage, and some species make excellent shade trees. The large seeds are not edible.

Some species, as AE. Hippocastanum and AE. carnea are popular shade and street trees. They leaf early and soon give a dense shade. The shrubby species are well adapted for borders of larger groups or as solitary clumps on the lawn, particularly M. parviflora, with its slender panicles of white flowers; similar in habit and effect but with bright scarlet flowers, are AE. discolor, AE. georgiana and AE. splendens. Most of the species are hardy North, but the Californian and Himalayan species are suitable only for the southern states. They grow best in loamy and moist soil.

Propagation is by seeds to be sown in autumn or stratified, or by side-grafting and budding on common species, and the shrubby forms also by layers; AE. parviflora is propagated also by root-cuttings.
