Aromatic plants are ecologically and economically valuable species in landscaping, which play important role in air purification, mosquito control, landscaping design, physical and mental health regulation, etc. This study investigated the species, life forms, aroma types, fragrance sources, flowering periods, and application frequency in 10 parks in Guangzhou. The results revealed a total of 109 aromatic plant species belonging to 95 genera and 54 families. Trees accounted for the most significant proportion at 51%, followed by shrubs. The aroma types included fragrant, highly fragrant, lightly fragrant, fresh fragrant, and woody fragrant. Flowers were identified as the primary source of fragrance in aromatic plants. A comprehensive evaluation of aromatic plant resources was conducted using the Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to an Ideal Solution (TOPSIS). The most important criteria were identified as health-promoting properties, followed by aroma and ornamental value. Comfort and pleasure were the most important indicators for aromatic plants. According to the results, the 109 aromatic plant species were classified into three levels: Level I “excellent” (31 species), Level II “good” (37 species), and Level III “moderate” (41 species).
