Aspidistra was a British mediumwave radio transmitter used for black propaganda and military deception purposes against Nazi Germany during World War II. At one time, it was the most powerful broadcast transmitter in the world. Its name - after the popular foliage houseplant - was inspired by the comic song The Biggest Aspidistra in the World, best known as sung by Gracie Fields. After the war, Aspidistra and other transmitters at Crowborough were used for BBC External Service broadcasts to Europe. The station closed in 1982.
