The duchess herself is an unlikely patron. Until 1995, she was just Jane Percy, mother of four. Then in 1995 her husband unexpectedly became the twelfth Duke of Northumberland following his brother's untimely death, and the next thing they knew they had a castle to deal with. As she inspected her newly inherited digs and expansive gardens, much of which had been meticulously designed by the famous landscape designer Capability Brown, she came across an overgrown, neglected section. Formal gardens had been planted in that spot by the first duke in 1750, and it passed through several incarnations until World War II, when it was converted from a place of Italian ornamental splendor into a victory garden of vegetables. By 1950, it had closed. She decided to restore it, not to its former glory, but into a new, modern garden.
Because the danger posed by poisonous plants is very real (some can kill or sicken just through touch), some plants are caged, and the garden is secured each evening behind gates under a 24-hour security watch.Other parts of the garden include an enormous multi-level treehouse and a bamboo labyrinth. You may also find the looming Alnwick Castle strangely familiar, having seen it stand in as Hogwarts in the first two Harry Potter films.
