cam·pi·on 
(kămpē-ən)
(kămpē-ən)n.
Any of several plants of the genera Lychnis and Silene native chiefly to the Northern Hemisphere and having variously colored flowers with notched or fringed petals.
[Early Modern English campion, perhaps from Middle English campion, champion (the flowers being so called because victor's chaplets were woven from them), from Anglo-Norman, from Medieval Latin campiō, campiōn-; see CHAMPION.]
