Some trees were added to the plantings, notably the limes of the Lime Walk. A bed of "Magnolia liliiflora" 'Nigra' is at the southern end of the Lower Courtyard, and some "Magnolia grandiflora" are on the walls of the Top Courtyard. A coral tree is in the Lower Courtyard. Some "Malus" and "Prunus" previously in the Rose Garden died out, as have "Robinia pseudoacacia", "Cercidiphyllum japonicum", and "Koelreuteria paniculata" in the Cottage Garden. A catalpa was planted as a focal point of the Lower Courtyard lawn in 1932, and Nicolson liked to sit beneath it and read, but it died in the 1960s.
