Rosa davurica, commonly known as Amur rose, is a plant in the family Rosaceae, native to eastern Siberia, Mongolia, northern China, Korea, Sakhalin, and Japan. The specific epithet davurica is a geographical descriptor derived from Dauria, a historical region in Siberia where the species is naturally found. The fruit of Rosa davurica, referred to as Cimeiguo in Chinese, is a rich source of vitamins and minerals, notably vitamins A, C, and E, flavonoids, and other bioactive compounds. It also contains essential fatty acids — a feature not typical for fruits.
