Ginkgo biloba, also known as Gingko or Maidenhair tree, is the only living species in the class Ginkgoopsida, all others being extinct. It is similar to fossils dating back to the Jurasic period. Widely planted as an ornamental tree, Ginkgo is considered to be Endangered in the wild; populations are apparently confined to Xitianmu Mt., Zhejiang, China.
Ginkgos are large trees, normally reaching 20 to 35 metres in height with an angular crown and long, somewhat erratic branches. It is usually deep rooted and resistant to wind and snow damage. Young trees are often slender, and sparsely branched. During autumn, its leaves turn a bright yellow before falling, sometimes within one to fifteen days. Ginkgos are long-lived, with some specimens claimed to be more than 2,500 years old.
