Abstract:Citrus is an important economic and landscaping plant in Chinese traditional gardens characterized by its unique construction techniques and cultural connotations. This research firstly analyzes botanical texts, garden poetry, garden records from various dynasties, along with relevant visual materials, to define 'citrus' in ancient China, trace its evolving cultivation methods across dynasties and the changes in aesthetic tastes. The results show that from the Pre-Qin Dynasty to the Late Qing Dynasty, the configuration of garden citrus underwent an evolutionary process from an independent, rough layout to a more delicate integration with other garden elements. In terms of aesthetics, the focus shifted from the early glorification of its form, color, and status as a tribute to a gradual appreciation of its aroma, eventually emphasizing the aesthetic dimension of leisure and utility. This evolution also reflects the integration of regional folk culture, thereby imbuing the garden citrus with new cultural connotations. The history of citrus landscaping mirrors the transition of traditional garden plants from singular utility to artistic ornamentation, providing a valuable reference for a deeper understanding of the history of landscaping with traditional garden plants.
