The Bodhi or Bo tree (Ficus religiosa) the Buddha sat under to become enlightened is the "world's oldest documented living tree." There are of course much older undocumented trees. It is a kind of fig or pipal tree, whose wonderful but small fruit is only eaten as starvation rations during famine. The original tree in India was intentionally destroyed by Muslim marauders incensed to see a "tree" being "worshipped." Of course, people were honoring the living tree as a way of honoring the Buddha's accomplishment by proxy. Those who destroyed it were apparently not aware that a branch had been taken and planted in Sri Lanka in ancient times, where it has survived, prospered, and grown to enormous size.
This special religious ceremony was attended by the Maha Sangha (Greater Order, comprised of representatives from the various monastic groups or nikayas in Sri Lanka) led by the chief incumbent senior monk (Atamasthana Adhipati), Ven. Pallegama Siriniwasa, and a large number of devotees including North Central Province Governor, Karunaratne Divulgane, Chief Minister Berty Premalal Dissanayake, and members of parliament and provincial councilors.
The sapling was placed in a gilded pot by Chief Minister Dissanayake. After a parade in honor of the Bo-sapling, it was taken in a special motorcade to Anuradhapura city then airlifted to Dambakolapatuna on the Jaffna peninsula on the north coast of the island escorted by Dr. Palitha Mahanthegama. Other politicians and officials from the Ministry of Buddhist Affairs as well as Naval personnel were also present. Source
