The Rose Garden contains 24 separate beds of roses, each of which is planted with an impressive 60 rose bushes of a different variety. No two adjacent beds are of a similar colour, in order to make it as bright as possible.
When the Queen is in residence, gardeners arrange a selection of seasonal posies for her every Monday, featuring a menagerie of evergreen leaves and colouful berries.
