Ginkgo is one of the oldest trees in the world. It is a unique species of tree with no close living relatives and classified in its own division.

For centuries it was thought to be extinct in the wild, but is now known to grow in at least two small areas in Zhejiang province in Eastern China, in the Tian Mu Shan Reserve. One of the oldest Ginkgo trees, which is four centuries old, is in the Yuyuan Garden, Shanghai, China.

China is not only the home of Ginkgo, but also one of the earliest countries that cultivate, use and research Ginkgo with the most abundant results.
