The oldest tree known to have been planted by a human rather than by natural seeding is a 2,300-year-old sacred fig or bo-tree (Ficus religiosa) that has been named Sri Maha Bodhiya, and stands in Anuradhapura, Sri Lanka. It was planted there in 288 BC. The mother tree from which this specimen was propagated was none other than the famous Bodhi tree under which Siddhartha Gautama the Lord Buddha was sitting when he gained enlightenment.
