Ginkgo biloba is a rare tree species left over from Mesozoic era, and it is a specialty of China. Born in acidic yellow soil with good drainage at an altitude of 500- 1000m, it is often mixed with coniferous and broad-leaved trees such as Cryptomeria fortunei, Torreya grandis and Orchidaceae, and grows vigorously. Gardens in Korea, Japan, Europe and America are cultivated.

Ginkgo biloba is the only ancient ginkgo plant that lives on the earth. It first appeared in the Carboniferous period 345 million years ago, so it is considered as the first living fossil in the world and a giant panda in the plant kingdom.
More than 2 million years ago, after the Quaternary Glacier Movement, the earth suddenly became cold, and most ginkgo plants in other parts of the world became extinct, only China survived. Therefore, other Ginkgo biloba around the world are directly or indirectly imported from China. Ginkgo biloba was not only introduced to neighboring Japan and the Korean Peninsula, but also settled in Europe and America.
