Both Suxin and Moli are foreign flowers introduced into China before the Tang dynasty. Renowned for their pleasant scents，these flowers gained high popularity in the Song dynasty，resonated with the flourishing of the gentry taste of daily life. With the similarities of the appearance of the plants as well as the color and size of the flowers，it was difficult for most of the people in the Song dynasty to discern the differences between them. As the first step of incorporating the flowers from abroad into the society of China，translation of the names of the flower was not so simple as the literary process seemed to be. Suxin is a Sinicized name，while Moli is a direct translation of the Sanskrit name of the flower. Different strategies of translation reflect the divergence of routes in cultural adaptations of foreign plants. Suxin was mainly considered as a flower with strong connections with the city of Guangzhou. Contrasted with the limited regional influence of Suxin，Moli succeeded in building up its spatial and symbolic superiority over its counterpart. A comparative study between the process of social knowledge construction on these two flowers in the Song dynasty will prove that different strategies of foreign plants nomenclature suggest various solutions of cultural adaptations. Based on the analyzing of the policies of foreign plants nomenclature，this paper argues that the unparallel process of localization which Suxin and Moli experienced in the Song period was determined by the uneven incorporation of Fujian and Guangdong into the “great tradition”. While Moli gained its fame as the Flower of Min region （minhua），its foreign origin gave way to its regionality，which in the future would secure its national characteristic.
