The last of the famous Mitford sisters, she moved to Chatsworth in the Peak District after marrying Andrew Cavendish, who became the 11th Duke of Devonshire.
She transformed Chatsworth to one of Britain’s leading tourist attractions. Crucial to the estate's success were its breathtaking gardens.
The garden covers 105 acres.
The kitchen gardens were laid out during the winters of 1991/2 and 1992/3. A huge variety of fruit, salad, cut flowers and vegetables are grown here, including ‘mummy peas’, allegedly grown from peas discovered in Tutankhamun’s tomb in 1922.
The yew maze was designed in 1962 on the site of what was once the Great Conservatory.
The Rose Garden dates from 1939.
Every year, an impressive Sotheby's sculpture show takes place in the garden.
