There are a number of key differences between the Chinese chestnut tree and the American chestnut tree. For example, the American chestnut tree grows taller than the average Chinese chestnut tree. The leaves of the Chinese chestnut tree are wider and glossier compared to the narrow, matte leaves of the American chestnut tree. Finally, the American chestnut tree is critically endangered, while the Chinese chestnut tree is classified as a plant of least concern when it comes to conservation efforts.

Let’s go over all of these differences in more detail now.

Chinese Chestnut vs American Chestnut: Classification

While they are closely related to one another and can be difficult to tell apart, Chinese chestnut trees and American chestnut trees are classified differently from one another. Both belonging to the beech family and the Castanea or chestnut genus, Chinese chestnut trees are classified as Castanea mollissima, while American chestnut trees are classified as Castanea dentata.

It can be difficult to tell an American chestnut tree apart from a Chinese chestnut tree, given how closely related they are. However, there are a few things you can use to identify them both as individuals. For example, the Chinese chestnut tree grows slightly shorter than the American chestnut tree overall. In addition, Chinese chestnut trees have more spreading branches compared to the narrow and upright branches of the American chestnut tree.

One of the main ways to tell these two trees apart lies in the shape and structure of their leaves. For example, American chestnut leaves are narrower and more matte in color compared to the wide and glossy leaves of the Chinese chestnut plant. American chestnut leaves also have distinctly toothed edges, while Chinese chestnut leaves have less obvious teeth. Finally, Chinese chestnut seed pods are typically larger than American chestnut seed pods, but only slightly.

Chinese Chestnut vs American Chestnut: Uses

Both Chinese chestnut trees and American chestnut trees have very similar uses to each other. Both of these trees are prized for their edible nuts, and the American chestnut is credited with being roasted over an open fire. However, Chinese chestnuts are still eaten today, while American chestnuts are rarely eaten, given their overall scarcity. Once upon a time, American chestnut wood was prized for its durability, and you may be able to find some antique American chestnut furniture nowadays, something that Chinese chestnut wood is not typically used for. 

Chinese Chestnut vs American Chestnut: Origin and How to Grow

The origins of the Chinese chestnut tree in the American chestnut tree are different from each other, likely something you could have already guessed. For example, Chinese chestnut trees are native to China and Korea, while the American chestnut tree is native to the Eastern United States. Both of these trees grow in a similar way, preferring full sunlight and acidic soil to thrive

The final key difference between the Chinese chestnut tree and the American chestnut tree lies in their conservation status or rarity as a plant. The Chinese chestnut tree is classified as a plant of least concern, but the American chestnut tree is critically endangered. This is because of chestnut blight, a plague that targets chestnut trees.
American chestnut trees are particularly susceptible to chestnut blight, and this disease has nearly wiped out all of the trees in America currently. The Chinese chestnut tree is more resistant to chestnut blight compared to the American chestnut, and it is much more readily available by comparison.
