The Crimson Gardenia is a 1919 American silent adventure drama film directed by Reginald Barker and starring Owen Moore. Based on the short story of the same name by Rex Beach.
Bored millionaire Roland Van Dam travels to New Orleans during Mardi Gras, where he is mistaken for an escaped prisoner named Emile Le Duc by his cousin, Madelon. She was told that Emile would be recognizable by his red gardenia, that coincidentally Roland also wears. Emile's gang kidnaps him, thinking that Emile had betrayed them, but he escapes. When the real Emile dies, Madelon is convinced by his gang that Roland is a secret agent and killed Emile, so she leads Roland to her uncle's home, who is the leader of the gang. Here she discovers that Roland is innocent and wants to escape with him. While being interrogated, he is able to convey the danger to a telephone operator who transfers the call to the policed. They are rescued and Roland marries Madelon.
The Crimson Gardenia was filmed on the Goldwyn Culver City lot, with the New Orleans sets designed by Hugo Ballin.
