An analytic hierarchy process (AHP) was employed to establish a landscape value evaluation model for 20 common species of perennial flowers in the flower border of Hefei City. With the overarching objective of determining the application value of the flower border, 10 evaluation factors were identified and subsequently classified into 3 distinct grades. Grade I (L > 2.5) was defined as perennial flower resources with the highest development and utilization value, including only one species of Salvia farinacea. Grade II (2.0 ≤ L ≤ 2.5) was defined as perennial flower varieties suitable for most areas, encompassing 9 species of plants, such as Taraxacum mongolicum. Grade III (L < 2.0) was defined as perennial flower varieties with low application value, encompassing 10 species of plants, such as Ruellia brittoniana, but lacking the value of further popularization and application. Consequently, the proportion of their application in the flower border should be reduced. The evaluation results can serve as a theoretical foundation for the implementation of perennial flowers in urban flower borders. [ABSTRACT FROM AUTHOR]
