Penelope Mary Fitzgerald was a Booker Prize-winning novelist, poet, essayist and biographer from Lincoln, England. In 2008 The Times listed her among "the 50 greatest British writers since 1945". The Observer in 2012 placed her final novel, The Blue Flower, among "the ten best historical novels". A.S. Byatt called her, "Jane Austen’s nearest heir for precision and invention."

The Blue Flower is the final novel by the British author Penelope Fitzgerald, published in 1995. It is a fictional treatment of the early life and troubled relationships of Friedrich von Hardenberg who, under the pseudonym Novalis, became a foundational figure of German Romanticism.
