Photos: Survivor Tree Grows at 9/11 WTC Memorial

A pear tree that was reduced to one living branch in the 9/11 attacks is now a feature of the National September 11 Memorial in New York City. 

The scorched tree, about eight feet tall and covered with ash, was recovered from the World Trade Center and replanted in a Bronx park, where a nursery manager didn't expect it to survive.

But new growth sprouted in spring 2002 and the tree managed to survive another calamity when it was uprooted in a storm in March 2010.

The tree is now more than 30 feet high and is anchored by special cables at the National September 11 Memorial in New York City. It was replanted at the World Trade Center site in December 2010.
