The Story of the Ohio Buckeyes

In our previous postwe introduced the story of the Ohio Buckeye, the origin of the term ‘buckeye’, the tree’s scientific name (Aesculus glabra), its relationship with the OSU mascot, Brutus, and how it was introduced to football fans of Ohio in 1987. Here, we continue with the story of the buckeye, but with a different focus. We will show how the Ohio Buckeye is both similar and different from other buckeyes, discuss its habitat, flowers, fruits, and how you can grow your own buckeye in your backyard.

Diversity

Currently, there are 13 species of buckeyes in North America, Europe and Asia. Six species are native to the United States. In Ohio you can find two native and several cultivated species. All buckeyes have large compound leaves made up of 5 to 7 leaflets per leaf that radiate from the same point at the end of a leaf stalk. They range from large trees to shrubs. The native species are the Ohio Buckeye (Aesculus glabra) and the Yellow or Sweet Buckeye (Aesculus octandra).

Non-native species cultivated in Ohio include the European Horse Chestnut (Aesculus hippocastanum), and the southeastern US Red Buckeye (Aesculus pavia). Most species of buckeyes are bee pollinated; the Red Buckeye is hummingbird pollinated and its flowers are red and tubular.  The hybrid between the Ohio Buckeye and the Sweet Buckeye, called Maryland Buckeye (Aesculus x marylandica), is also cultivated in Ohio.

Habitat

All buckeyes are found in woodlands and forests of various types, along riverbanks and floodplains. The introduced species and the hybrid plants make attractive trees in lawns, gardens, parks and on roadsides.

Flowers

The flowers are clustered together forming a cone-shaped panicle, a loosely branched inflorescence. They range in color from white (Horse Chestnut), to pale greenish yellow (Ohio Buckeyes), yellow or reddish (Sweet or Yellow Buckeye) to red (Red Buckeye).

Fruits

The fruits are leathery and open from the top when fully mature. In Ohio Buckeyes and Horse Chestnuts, the fruits are prickly due to short spiny outgrowths while in Sweet Buckeye, they are not. Despite similar fruits, Horse Chestnuts can easily be differentiated from Ohio Buckeyes based on the leaflets, which are mostly 7.

Properties

In the past, the seeds of the Ohio Buckeye were used as a source of oil for lamps, as an insecticide and as a paste for book binding. The wood was used in making bowls, spoons, handles and boxes. Since the wood is easy to carve, it was also used in making artificial limbs. Extracts from the bark were also used to dye leather. Today, the seeds are carried by some people as a good luck charm and they are treated in much the same way as a four-leafed clover. Some people also associate curative properties to the seeds, particularly for rheumatism.

Grow your own Buckeye

Buckeyes may be cultivated and propagated and can easily be propagated from seeds. Collect the seeds and do not allow them to dry out. Simply place several, fresh seeds, since not all may germinate, in shallow soil, about an inch deep. Gently press the soil down and keep them moist. Some seedlings will develop the next spring. If several seedlings come up, remove all except one so that this will develop into a tree. The seeds require three or more months of cold treatment (34-40 F) for good sprouting.

According to records, the Ohio Buckeye is not widely cultivated because “nurseries tend to emphasize the showier horse-chestnut, and perhaps also because of its poisonous properties (a few communities have even enacted ordinances prohibiting its cultivation). However, buckeyes make attractive and interesting landscape plants and are not hard to grow. One disadvantage is that the leaves tend to fall a bit earlier than [those of] other trees, especially in a dry summer, and, of course, the fruits and seeds drop to the ground below after they ripen. But they are not particularly difficult to remove from a lawn”.

What is a buckeye?

During the football season, we are accustomed to seeing Brutus Buckeye dancing on the sidelines, shaking his enlarged head, and helping to stimulate enthusiasm for our team on the gridiron. Opposing teams usually have mascots that are more easily recognizable, such as a lion, or badger, or valiant soldier. What, then, is a buckeye?

The term “buckeye” originated from indigenous peoples noticing that European immigrants coming into Ohio had larger eyes, similar to those of the male (buck) deer. The settlers, therefore, were called buckeyes.

One of the native trees in Ohio, which we now call the Ohio buckeye, has large seeds that also resemble large buck eyes, which led to application of the name as the buckeye tree. This common name was applied to the entire tree and any of its parts. Our mascot, Brutus, represents one seed of the Ohio buckeye tree, attached, obviously, to a human body. This is a most unusual mascot. Most institutions use fierce animals or symbols of strength; very few have a plant. A seed in flowering plants is always formed within a fruit, which in the case of the Ohio buckeye is large, leathery, and slightly prickly. One to several seeds are formed inside. The tree can be up to 30 feet tall, and the leaves are divided into segments.

One of the attractive aspects of the buckeye tree is the colorful display of yellow flower clusters (inflorescences) that appears in late Spring throughout the state. The buckeye is used by The Ohio State University as part of the University seal, showing a leaf with two fruits (Fig. 3).

The Ohio buckeye came into the scientific world as a new species, under the name Aesculus glabra, described by Professor Carl Ludwig Willdenow, Director of the Botanical Garden in Berlin, Germany. Seeds were collected about 1803 from some unknown locality in Ohio or neighboring state and sent to Berlin for germination. It grew successfully in the garden, and when the small tree flowered, a specimen was prepared, with Prof. Willdenow describing it as new to science in 1809.  This specimen is called the nomenclatural type (holotype) and is forever associated with its scientific name.  In a certain sense, this can be regarded as the original buckeye.

Because of the importance of Aesculus glabra to the state of Ohio and The Ohio State University, a campaign was initiated in 1985 to bring the original buckeye to campus. This was not an easy endeavor, because the Berlin Botanical Garden and Museum had never loaned any of the historically important Willdenow specimens to another institution.  After serious negotiations, and in recognition of the help that the United States had made through the Marshall Plan to reconstruction of Germany after World War II, the holotype of the Ohio buckeye was loaned to Ohio State in the summer of 1987 for several months. It was hand carried from Berlin to Columbus. Thanks to financing from the office of the President at OSU, a special mount was made for the specimen, which allowed it to be placed on an easel for display.  Housed in the Herbarium of the University, at that time still in the Botany and Zoology building at 12th and Neil Avenue (now Jennings Hall), it was taken on tour to alumni clubs in the state. Most exciting, however, was the presentation of the holotype on 14 November 1987 on the 50-yard line during the Ohio State-University of Iowa home game to the assembled fans. President Jennings formally received the specimen for the University, assisted by me and Prof. Daniel Crawford, the Chair of the Department of Botany.  Even Brutus had the opportunity to get to know his scientific origins.

Different parts of the buckeye tree are used as memorabilia or symbols. Very popular are necklaces made of actual seeds, which can be worn in the stadium to help cheer on the players. Also popular, especially to folks with a sweet-tooth, are the buckeye candies resembling seeds, with peanut butter centers bathed in chocolate.

In addition to these obvious symbols, there are countless items in souvenir shops that have images of buckeye seeds and/or leaves, ranging from socks to hats, and including underwear and toilet seats!  The football players even receive a buckeye leaf on their helmets, a badge of honor, after completing an outstanding play during the game.

The Ohio buckeye, therefore, is an important part of the fiber of life at Ohio State University. It is satisfying that the center of all the attention is a plant. We in the Herbarium are delighted that all members of the university community are continually reminded of the importance of the botanical sciences, especially in the Autumn season during each football game!
