What are the longest-living trees in the United States?Of the 850 different species of trees in the United States, the oldest is the bristlecone pine, which grows in the deserts of Nevada and southern California. Scientists have identified one of these trees as being 5,062 years old as of 2012. They believe they can live as long as 5,500 years. Although this seems old, it is actually very young when compared to the oldest surviving species in the world, the maiden-hair tree, or Ginkgo biloba, of China. This tree first appeared during the Jurassic era some 100 million years ago. Also called icho, or ginkgo, meaning “silver apricot,” this species has been grown in Japan since 1100 B.C.E.. |
