How old is old? Gingko might know. In the tree of life, Gingko branched off so long ago that it has no close relatives. It is considered a living fossil along with the Dawn Redwood and cockroaches. One Gingko is reported to be 2,500 years old. Six Gingko survived the atomic bomb in Hiroshima in 1945 where almost nothing else did. No one is sure if any Gingko remain in the wilderness. The Gingko we see today are cultivars from a reserve of trees found in China that were thought to have been planted and maintained by monks. Gingko is the national tree of China.
At the Botanical Center, the Gingko trees are found along the entry path from the admission booth to the Conservatory.
