As they were cleaning up after 9/11 they pulled debris off of an 8 ft. tall pear tree that was damaged and scorched but it appeared to still be alive so they called a local nursery to remove it and see if they could save it. At that point everyone was looking for any signs of life whether animal, human, or in this case, a tree.
The tree survived and they recently planted it at the memorial site along with over 300 other trees. But this tree stands out as it is over 30 feet tall. It has its own name: "The Survivor Tree."
