Helen has long been interested in the history of orangeries, and so was delighted to act as one of the advisers on the re-instatement of the orangery at Knole Park in late 2009/early 2010. The position brought unexpected archival dividends for her research into historic orangeries, and prompted further research using the sketch books and diaries of Sir George Scharf as a manuscript source. This article gives a first outline of some of her findings.
