To the west of the driveway is a large paperbark (Melaleuca leucadendra) and peppermint (Eucalyptus nicholli) planted by Queen Elizabeth II and the Duke of Edinburgh in 1954 during the first visit of a reigning monarch to Australia. Many of the garden's trees are ceremonial plantings. Among the roses on the Eastern Terrace the "Dame Marie Bashir Rose" can be found (bred in that Governor's honour), as well as the "Governor Macquarie" rose Dame Dr Bashir planted in 2009 as patron of the Rose Society of New South Wales. Dame Marie Bashir was just one of the many governors past and present with a passion for plants and their pollinators.
