The Gingko or maidenhair tree is native to southeast Asia (Britannica, 2019). This tree dates back as early as 200 million years. (Cohn, 2013) A living tree in China is dated at 3,500 years old (Triplett & Overstreet, 2004). This species was brought over to the United States in 1784 (Triplett & Overstreet, 2004). This type of tree, which is often used as an ornamental tree in the United States do to its insect and fungal resistant properties (Britannica, 2019), is a cultural icon in many Asian countries. This tree has also been found to have many medical uses as well, including memory improvement, increase of blood flow in capillaries and arteries, and as a treatment for erectile dysfunction (Triplett & Overstreet, 2004). The Gingko tree has been used for so many medical issues that most places do not even try to list all of them. This species of tree is easily identifiable by its fan shape leaves and fishy smell. It is also the only surviving member of the Ginkgo family. There are very few wild Gingko trees left. These trees are considered endangered, but they are being kept alive and strong by the domestic use of this tree. This is a wonderful example of how human intervention kept a species from going extinct.
I learned about this tree through a biology class and by finding one of these trees on my college campus. This species has a very interesting history. The picture above was taken for a project I did in the previously mentioned biology class, and shows the characteristic fanned leaf structure. I encourage you, if you are looking for more information on this species, to start with the sources that I have cited in this post.
