The ginkgo tree, also known as the maidenhair tree, is one of the oldest living tree species, with a history dating back over 270 million years. Native to China, these trees have been cultivated for thousands of years for their medicinal properties, edible nuts, and ornamental value. However, one of the most distinctive and often talked-about characteristics of ginkgo trees is their unique and pungent smell. In this article, we will delve into the world of ginkgo trees and explore what they smell like, why they have this distinctive aroma, and the cultural significance of their scent.
Introduction to Ginkgo Trees
Ginkgo trees are large, deciduous trees that can grow up to 100 feet tall, with a broad, fan-shaped canopy and long, slender branches. They are known for their striking yellow foliage in the fall, which turns a vibrant golden color before shedding. The trees produce small, greenish-yellow flowers in the spring, which are followed by the production of fleshy, apricot-like fruits that contain a single seed. The fruit is the main culprit behind the distinctive smell of ginkgo trees, but more on that later.
The Smell of Ginkgo Trees: A Description
The smell of ginkgo trees is often described as pungent, earthy, and slightly sweet. When the fruit is ripe and falls to the ground, it releases a strong, unpleasant odor that is often compared to the smell of vomit, sewage, or rotten eggs. This smell is caused by the presence of butyric acid, a compound that is also found in human sweat and is responsible for the characteristic odor of body odor. The smell of ginkgo trees is so potent that it can be detected from a distance and can be overwhelming to those who are sensitive to strong odors.
Why Do Ginkgo Trees Smell So Bad?
So, why do ginkgo trees produce such a strong and unpleasant odor? The answer lies in the tree’s evolutionary history. Ginkgo trees have been around for millions of years, and their ancestors date back to a time when the Earth’s atmosphere was very different from what it is today. During this time, the trees had to compete with other plants and animals for resources, and the production of a strong, unpleasant odor may have been a way for the trees to protect themselves from predators and attract pollinators.
The Role of Butyric Acid
Butyric acid is a key component of the smell of ginkgo trees, and it plays a crucial role in the tree’s reproductive cycle. When the fruit is ripe, it releases butyric acid into the air, which attracts pollinators and seed dispersers. The smell of butyric acid is also a warning signal to potential predators, telling them to stay away from the tree and its fruit. This is an example of a phenomenon called “chemical defense,” where plants use chemical signals to protect themselves from harm.
Cultural Significance of Ginkgo Tree Smell
The smell of ginkgo trees has significant cultural and historical importance, particularly in China and other parts of Asia where the trees are native. In traditional Chinese medicine, ginkgo trees are considered a symbol of good health and longevity, and their fruit and leaves are used to treat a variety of ailments. The smell of ginkgo trees is also associated with the changing of the seasons, and is often seen as a sign of autumn’s arrival.
Ginkgo Tree Smell in Urban Environments
In urban environments, the smell of ginkgo trees can be a source of controversy. On the one hand, the trees are prized for their beauty and historical significance, and are often planted in parks and gardens. On the other hand, the smell of the fruit can be overwhelming and unpleasant, particularly in confined spaces. Many cities have banned the planting of ginkgo trees in certain areas, or have implemented measures to mitigate the smell, such as removing the fruit or using odor-neutralizing technologies.

What is the source of the unique smell of ginkgo trees?
The source of the unique smell of ginkgo trees is a topic of much debate and research. The smell is often compared to the odor of vomit, sewage, or rotten eggs, and is particularly noticeable when the trees’ fruit is ripe and falls to the ground. The fruit of the ginkgo tree contains a chemical called butyric acid, which is also found in sweaty gym socks and vomit. This chemical is responsible for the strong, pungent smell that is often associated with ginkgo trees.
The butyric acid in ginkgo fruit is thought to serve as a defense mechanism to deter herbivores and other animals from feeding on the fruit. The smell is also believed to play a role in the tree’s reproductive cycle, as it may attract certain insects and other animals that help to disperse the tree’s seeds. Despite the strong smell, many people find the ginkgo tree to be a beautiful and attractive addition to landscapes and gardens. The tree’s unique foliage and stunning fall colors make it a popular choice for gardeners and landscape designers.
Why do ginkgo trees smell so bad in the fall?
In the fall, ginkgo trees smell particularly bad due to the ripening and falling of their fruit. As the fruit ripens, it softens and splits open, releasing the butyric acid and other chemicals that give the tree its characteristic smell. The smell is often more pronounced in the fall because the fruit is more abundant and the weather is typically warmer and more humid, which allows the chemicals to linger in the air. Additionally, the fall is a time of year when many ginkgo trees are dropping their leaves, which can also contribute to the smell.
The combination of the butyric acid from the fruit and the decomposing leaves can make the smell of ginkgo trees in the fall particularly overpowering. However, it’s worth noting that not all ginkgo trees produce fruit, and those that are male or have been sterilized through grafting will not produce the same strong smell. If you’re looking to plant a ginkgo tree in your yard or garden, you may want to consider a male or sterile variety to avoid the smell. On the other hand, if you’re looking to attract certain insects or animals to your garden, a fruiting ginkgo tree may be a good choice.
Are ginkgo trees the only trees that produce a strong smell?
Ginkgo trees are not the only trees that produce a strong smell, although they are certainly one of the most notorious. Other trees, such as the black walnut and the pine tree, can also produce strong smells, although these are typically not as pungent as the smell of ginkgo trees. The black walnut tree, for example, produces a chemical called juglone, which can give off a strong, nutty smell. The pine tree produces a range of chemicals, including terpenes and resin, which can give off a strong, piney smell.
While these trees can produce strong smells, they are typically not as overwhelming as the smell of ginkgo trees. The smell of ginkgo trees is particularly unique and potent due to the combination of butyric acid and other chemicals that are present in the fruit. Additionally, the smell of ginkgo trees is often more noticeable because it is typically more concentrated and lingering, whereas the smell of other trees may be more fleeting or subtle. Overall, while there are many trees that produce strong smells, the ginkgo tree is certainly one of the most distinctive and memorable.
Can the smell of ginkgo trees be harmful to humans or animals?
The smell of ginkgo trees is not typically considered to be harmful to humans or animals, although it can be overwhelming and unpleasant.

However, these reactions are typically mild and temporary, and can be alleviated by avoiding the area or using protective measures such as masks or air purifiers.
It’s worth noting that the butyric acid in ginkgo fruit can be toxic to some animals, particularly small mammals and birds, if ingested in large quantities. However, this is typically not a concern for humans, as the amount of butyric acid present in the fruit is not sufficient to cause harm. Additionally, the smell of ginkgo trees is not typically considered to be a nuisance or a health hazard, and many cities and towns plant ginkgo trees in public spaces and parks. Overall, while the smell of ginkgo trees can be strong and unpleasant, it is not typically considered to be a health risk.
How can I reduce the smell of ginkgo trees on my property?
If you have a ginkgo tree on your property and are concerned about the smell, there are several steps you can take to reduce it. One option is to rake up the fruit as soon as it falls, which can help to prevent the butyric acid from being released into the air. You can also consider planting a male or sterile ginkgo tree, which will not produce fruit and therefore will not produce the same strong smell. Additionally, you can try using odor-absorbing materials such as baking soda or activated carbon to neutralize the smell.
Another option is to plant other trees or flowers that can help to mask the smell of the ginkgo tree. For example, fragrant flowers such as roses or lavender can help to overpower the smell of the ginkgo tree, while trees such as pine or spruce can help to absorb the odor. You can also consider using a lawn mower or leaf blower to regularly clean up the fruit and leaves, which can help to reduce the amount of butyric acid that is released into the air. Overall, there are several steps you can take to reduce the smell of ginkgo trees on your property, and the best approach will depend on your specific situation and needs.
