acres to supply the growing household. Kitchen gardens received their greatest elaboration in the second half of the nineteenth century. Many of these labor-intensive gardens fell into disuse in the twentieth century, but some have been revived as decorative gardens, and others used to produce fruits, vegetables or flowers. Susan Campbell, in a book devoted to walled kitchen gardens, mentions several factors which contribute to how productive a kitchen garden is. Productivity depended upon the suitability of the situation, and successful gardens depended on the availability of water, manure, heat, wall space, storage space, workrooms, and most importantly, a dedicated team of gardeners. Examples British examples of walled gardens can be found at Alnwick Castle, Castle Bromwich Hall Gardens, Fulham Palace, Goodnestone Park, Luton Hoo, Polesden Lacey, Shugborough Hall, and Trengwainton Garden in England; Bodysgallen Hall (Wales); Edzell Castle, Muchalls Castle and Myres Castle (Scotland). The walled kitchen garden at Croome Court, Worcestershire is reputedly the largest 18th-century walled kitchen garden in Europe. It is in private ownership and has been restored by the current owners. In about 1806, a high free-standing east–west hot wall was built, slightly off-centre, serviced by five furnaces; this is historically significant as it is one of the first such structures to be built. The walled kitchen garden at Chilton Foliat, Wiltshire, was the subject of the 1987 television documentary series The Victorian Kitchen Garden. In literature In the story of Susanna and the Elders, a walled garden is the scene of both an alleged tryst and an attempted rape. Because of the walls, the community is unable to determine which actually occurred. In John William Waterhouse's interpretation of the myth of Cupid and Psyche, Psyche lived in Cupid's walled garden. Much of the storyline of Frances Hodgson Burnett's children's story The Secret Garden revolves around a walled garden which has been locked for ten years. The author was inspired by Great Maytham Hall in Kent. "Rappaccini's Daughter", a short story by Nathaniel Hawthorne, takes place almost entirely within the confines of a walled garden in which Beatrice, the lovely daughter of a mad scientist, lives alongside gorgeous but lethal flowers. In The Last Enchantment, the third book in Mary Stewart's novels of the Arthurian legend, Merlin constructs a heated wall for his garden at Applegarth.
