In order to screen out the plant suitable for summer flower border applications in Guangzhou, a field investigation of plant resources was carried out, and the Analytic Hierarchy Process(AHP) was used to evaluate from three aspects: ornamental, adaptability and planting maintenance. The results show that there are 80 species of flowering plants, belonging to 45 families and 71 genera, which are frequently used in summer landscape in Guangzhou. Among them, 16 species with high ornamental value, strong ecological adaptability and low maintenance and management input were screened out as class I flower border plants. In the criterion layer, the weight value of ornamental was the largest, and in the index layer, the weight value of flower color and flower quantity were larger, so the color design should be paid attention to in the plant configuration of the flower border. The flower border plants applied in Guangzhou in summer were mainly annual or biennial herbs, perennial herbs and shrubs, and the application of native plants were relatively few.
