NEW YORK (AP) Three communities struck with tragedy will receive seedlings from the September 11 Memorial Museum's Survivor Tree Program.

The group will announce Saturday that the seedlings will be sent to Newtown, Connecticut, Joplin, Missouri, and Madrid, Spain.

9/11 Memorial President Joe Daniels says the trees convey a shared strength in the face of tragedy.

The memorial tree program was started in 2013.

A Connecticut-based tree company partners with students at John Bowne High School in Queens to grow the trees.

They've previously been sent to parts of Queens after Superstorm Sandy, Boston in memory of the victims killed in the marathon bombing and Prescott, Arizona, to honor 19 firefighters who were killed in 2013.

The charred trunk of the pear tree was pulled from the rubble of the WTC site
