Abstract:In ancient Chinese culture, "Puwei" refers to two types of herbs with long leaves, named "Pu" and "Wei" respectively. According to modern plant taxonomy, plants named "Pu" probably refers to the plants of Typha in Typhaceae and Acorus in Araceae. There are many species, but most of them refer to Typha orientalis, Acorus calamus and Acorus tatarinowii. Plants named "Wei" refers to Phragmites australis in ancient Chinese culture. Since ancient times, plants named "Pu" and "Wei" have produced a lot of derivative benefits in terms of edible, medicinal, industrial and ecological value. The cultural connotation of the two in the development of material and spiritual civilization in ancient China has been elaborated from the aspects of records in ancient books, poems, calligraphy and painting, myths and legends, and traditional folk customs. Finally, the application of the two in the construction of modern garden water body and wetland landscape is introduced.
