Introduced by C. Sprenger, Dammann & Co., Naples, Italy, EU in 1893. Announced along with C. 'Italia', and caused much interest as their large flowers were considered to be a major breakthrough. To achieve this novelty, Herr Sprenger crossed C. 'Madame Crozy' with C. flaccida 'Le Roi'.
Synonyms: C. 'Austra', C. 'Canary Bird', C. 'Lemon Zest', C. 'Richard Wallace', C. 'Souvenir de Jeanne'. The blog yesterday featured C. 'R. Wallace', and examination of the photographs makes one wonder how anyone could ever have confused these two totally different cultivars.
