Despite being 400 years old and enduring a nuclear explosion, this little bonsai tree just keeps on growing. Planted in 1625, it lived only 2 miles from the drop site of the atomic bomb that destroyed Hiroshima in 1945. It was given as a gift to the United States in 1976 and is now housed at the National Arboretum, where it still continues to thrive. Source Source 2
