Hippocastanaceae (Horse-Chestnut Family)

Aesculus glabra (Ohio buckeye)
Makin, Julie
Ohio buckeye, a medium-sized, canopy tree, 50-75 ft. tall, is often used as an ornamental because of its interesting fruit and bright orange fall foliage. Branches bend toward the ground then arch back up, creating a rounded outline. Dense, attractive, deciduous foliage is palmately compound and the showy, erect blossom clusters are held at the ends of the twigs. The tree’s fruit is a nut encased in a spiny, splitting husk. Twigs and leaves often have a slightly unpleasant odor when crushed.

The state tree of Ohio, the Buckeye State. Pioneers carried a buckeye seed in their pockets to ward off rheumatism. The seeds and young foliage are poisonous, and the toxic bark was formerly used medicinally. Sometimes planted as an ornamental for the showy autumn foliage. The wood is used for furniture, boxes, flooring, and musical instruments. Caution: All parts of this tree are poisonous if taken internally. Keep away from livestock; seeds and fruits are attractive to children and are dangerous.
