In Shen Nong's Herbal, written during the Eastern Han Dynasty (206 B.C. to 220 A.D.), R. multiflora var. cathayensis was named "Qiang Mi" (in Chinese, a vine-like rose that is good for growing on walls). The 'Bai Ye' rose ("Rose with a hundred petals") described by Li Deyu, one of the prime ministers of the Tang Dynasty, in Records of Flowers and Plants in Pin Quan Shan is the R. multiflora var. cathayensis found growing in Shaoixing, Zhejiang today. Rosa multiflora var. cathayensis has many forms, which developed through more than 2,000 years of cultivation.
