A deciduous tree, upright, to 70 feet tall. USDA Zones 3-7
Buckeye, also known as American buckeye, Oklahoma buckeye (Aesculus glabra var. monticola), Texas buckeye (var. arguta) derives its unflattering common names from the disagreeable odor that results when the leaves are crushed. The tree is an attractive ornamental, but it has limited commercial use as sawtimber because of the soft, light wood.
Warning: buckeye is highly toxic when taken internally. (1)
Damaging Agents- buckeye is relatively free of insect pests but the sapwood timberworm, the lacebug (Corythucha aesculi), the chrysomelid (Derocrepis aesculi), and the walnut scale feed on buckeye. It is susceptible to a leaf blotch, which begins as brown spots or blotches on the leaves and may eventually involve all the leaves, giving the tree a scorched appearance. This disease may slow the growth rate but does no permanent damage to the tree and can be controlled on ornamentals. Powdery mildew also attacks the leaves of buckeye.
Buckeye poisoning affects the central nervous system of the animal. Prominent symptoms are an uneasy or staggering gait, weakness, severe trembling, and sometimes vomiting. Coma usually precedes death. Dilated pupils and congestion of the visible mucous membranes are commonly observed. Colic has been reported in poisoned horses .
