In the new film adaptation, keen-eyed viewers might notice that Mary’s first entry into the secret garden takes place not after finding a key, but after scaling a wall — the hidden key is introduced later.

Frances Hodgson Burnett kept a walled garden at Maytham Hall, her home near Rolvenden in Kent. The elaborate rose garden she created there was inspired by a garden of her childhood imagination.

Lattices of yellow or rose gold allow us to create a brickwork pattern, with white diamonds set in the motif. While stunning tsavorites, sapphires and diamonds represent flourishing flowers.
