On Sunday, September 11, 2011, the 9/11 Memorial will be dedicated and become open to the public, coinciding with the tenth anniversary of the attacks. Michael Arad, the architect of the Memorial, worked with the landscape architecture firm Peter Walker and Partners to design the landscape.
Four hundred and twenty two swamp white oaks (Quercus bicolor) were planted at the site, and all of the trees were harvested from within a 500-mile radius of the World Trade Center site, with additional trees coming from area in Pennsylvania and near Washington, D.C., the two other regions that were impacted by the attacks on September 11, 2001.
