The Highgrove Arboretum mural is hand-painted, referencing several mural wallpapers housed in the archive. The design includes acer, beech and Japanese maple grown in the magnificent Highgrove Arboretum. The three birch trees gifted by the Queen Mother frame His Majesty's Sanctuary alongside an abundance of hydrangeas, rhododendrons, magnolias and 'The Daughters of Odessa'.
