Flower borders are significant carriers of urban plant landscapes and key contributors to ecological development. Research on flower borders in Fuzhou began relatively late, and various issues have been identified in their application and form. To understand the current application status of flower borders in Fuzhou’s urban parks, a survey was conducted from 2023 to 2024 across 53 urban parks in the main urban area of Fuzhou, collecting data from 33 flower border sample plots in 17 urban parks. The results show that Fuzhou’s urban park flower borders include 218 species of plants from 168 genera and 79 families. Among them, there are 11 species of annual and biennial herbs, 107 species of perennial herbs, 80 species of shrubs, 15 species of trees, and 5 species of woody vines. Regarding the color distribution of flower border plants, red flowers accounted for the highest proportion at 34.59%. The most frequently used plant was Dracaena fragrans. However, the proportion of native plants in Fuzhou’s flower borders is low, at only 11.93%. The flower borders in Fuzhou exhibit low satisfaction in terms of planar design, plant species richness, and native plant application. To optimize the existing flower border landscapes, it is recommended to strengthen the design of plant grouping to enhance the landscape’s expressiveness. Integrating local plant resources can increase plant species richness in flower borders, promote biodiversity conservation and utilization, and create flower border landscapes with local characteristics.
