Origin

Mid 19th century: from an obsolete sense of poppy ‘a conspicuous or prominent person or thing’, probably with reference to Tarquinius Superbus, a king of ancient Rome who demonstrated how to deal with potential enemies by cutting off the heads of the tallest poppies in his garden (Livy 1.54.6).
