One more reference: "A yellow variety of this class that was greatly to be desired. In every way Chin Chin is as good a grower and free bloomer as Mme. Eugene Resal, from which it sported. As a yellow bedder, or for masses, this is grand. It keeps its colour--sulphur yellow--clear up to the last." Gardeners' Chronicle, February 26, 1910, p. 131.
