Les Rosati (Dr. Müller 1907) Upright plant, blooms through the summer. Medium size flower, double, petals imbricated, crimson-cherry-red, reflexes, back side pale salmon pink.
Peter Lambert gives Dr. Müller as breeder instead of Gravereaux. This was probably one of the roses Gravereaux received when he bought all of Dr. Müller's plants which Gravereaux then introduced under his own name. Les Rosati was the name of a group of rose lovers.

No. 8 came from the following cross: Pierre Notting was crossed with Safrano. The resulting best seedling was crossed with the seedling Mad. Bérard x Persian Yellow, resulting in the seedling No. 8 "Les Rosati". The plant grows very vigorously and is healthy, only the color reminds of the Lutea descent, the character only little. The color is rich, the petals are capuchin yellow, the upper edge red; a peculiar color.
