Landscape architect Frederick Law Olmsted Jr. designed the memorial landscape. The Olmsted planting plan installed at the time of construction featured a simple design within a circular driveway; primarily evergreen trees with limited flowering trees and shrubs. The design was perceived as too thin, so white pines were added and some other plantings took place before the dedication in 1943. Many changes to Olmsted's plans occurred in the 1970s, while 1993 and 2000 restorations have attempted to restore integrity to Olmsted's altered design. President Roosevelt ordered trees to be cut so that the view of the memorial from the White House would be enhanced; additional tree pruning was completed to create an unobstructed view between the Jefferson Memorial and Lincoln Memorial.
