The Horsechestnut




(_Aesculus hippocastanum_)



Distinguishing characters: The *sticky* nature of the *terminal bud* and

its *large size* (about an inch long). The bud is dark brown in

color. See Fig. 20.



Leaf: Five to seven leaflets, usually seven. Fig. 21.



Form and size: Medium-sized tree, pyramidal head and coarse twigs.



Range: Europe and eastern United States.



Soil and location: Prefers a deep, rich soil.



Enemies: The leaves are the favorite food of caterpillars and are

subject to a blight which turns them brown prematurely. The trunk is

often attacked by a disease which causes the flow of a slimy

substance.



Value for planting: On account of its showy flowers, the horsechestnut

is a favorite for the park and lawn.



Commercial value: The wood is not durable and is not used commercially.



Other characters: The _flowers_ appear in large white clusters in May

and June. The _fruit_ is large, round, and prickly.






Comparisons: The _red horsechestnut_ differs from this tree in having

red flowers. The _buckeye_ is similar to the horsechestnut, but its

bud is not sticky and is of a lighter gray color, while the leaf

generally has only five leaflets.
