This photograph of preserved roots from a sycamore tree was taken in 1950. The roots were spared from a newly dug utility ditch. The White House Grounds are an arboretum, and the trees are exceptionally well cared for. These roots can be used as grafts to grow a new, identical sycamore tree.

This photograph shows a work crew laying subflooring in the Center Hall on the Second Floor of the Executive Mansion. This work was part of President Harry S. Truman's large-scale 1948-1952 renovation of the White House.

This photograph was taken on the North Lawn of the White House Grounds in 1952. In this photograph, men oversee the transplantation of a tulip poplar on the grounds right in front of the North Portico of the newly renovated White House. President Harry S. Truman oversaw the eponymously named Truman renovation from 1948 to 1952.

This photograph captures the newly constructed West Wing with the remnants of the old White House Conservatory visible right behind the new wing. The Conservatory had previously taken up the west terrace of the Executive Mansion until 1902, when President Theodore Roosevelt began his plans to expand the White House. The Roosevelt renovation sought to increase living space and privacy for the first family in the Executive Mansion, moving the president's staff into the new wing.

This a photograph of one of the three historic elms, which were uprooted during the storm on July 30, 1913. This elm blocks the driveway leading to the North Front of the White House.

This photograph, taken in April 1962, captures the transplantation of a saucer magnolia in the Rose Garden on the White House Grounds. The Rose Garden, located on the South Grounds just outside the Oval Office, underwent a redesign from 1962 to 1963 under the guidance of landscape designer Rachel Lambert Mellon and First Lady Jacqueline Kennedy. In total, four saucer magnolias were transported from the Tidal Basin in Washington, D.C. to the Rose Garden. The redesign of the Rose Garden included the addition of new steps just outside the Oval Office, transforming the area into President John F. Kennedy's vision of a smaller, ceremonial location for formal events that would shorten White House traditions while maintaining a high level of prestige.

This black and white photograph is of the West Terrace under construction in 1902. Workmen in white coveralls pose on top of a scaffold that runs along the columns of the terrace. The Old Executive Office Building is visible in the background.
