The ginkgo biloba tree is exceptionally hardy. Its deep roots make it resistant to the wind and enable it to find moisture in harsh environments. The ginkgo biloba tree has existed for millions of years and is not similar to any other living species of tree, making it unique. Some of the ginkgo biloba trees alive today are over a thousand years old. The species is native only to China, but is widely cultivated across the globe due to its popularity as a culinary delicacy and herbal supplement.
