Taking the rock garden plants in Perennial Plants Garden of Beijing Botanical Garden, a total of 49 genera and 60 species of 22 families (including varieties) as the research objects, the Analytic Hierarchy Process (AHP) was used to evaluate the maintenance difficulty, ornamental value and resistance. A total of 32 species of rock garden plant resources with good garden application prospects were selected such as Chelidonium majus, Iris lactea var. chinensis, Potentilla anserina, Physostegia virginiana and et al., including 20 species of perennial plants, which enriched the plant selection of rock garden, added color to the landscape of rock garden in four seasons, and provided reference and demonstration for the construction of rock garden in northern China.
