Barnsley House, in the village of the same name, is one of those picture-perfect Cotswold manor houses of exquisite honey-coloured stone. Built in the last years of the 17th century it passed through various owners, and served as the Rectory, before being purchased by the Verey family in 1939. It came to fame a generation later when David Verey, an architectural historian, and his wife Rosemary inherited the house. Rosemary Verey went on to create one of the most famous gardens in Britain, and even those who have never visited (including, until this week, The Folly Flâneuse) would recognise the laburnum avenue underplanted with alliums that has graced many a calendar and greetings card.
