Aspidistra was a British medium wave radio transmitter used for black propaganda and military deception purposes against Nazi Germany during World War II. At times in its history it was the most powerful broadcast transmitter in the world. Its name – after the popular foliage houseplant – was inspired by the 1938 comic song "The Biggest Aspidistra in the World", best known as sung by Gracie Fields. The Crowborough station was run during the war by the British government's Political Warfare Executive (PWE).
