Most of them are perennials and the major plant species belong to Gramineae, Compositae, Lamiaceae and Liliaceae. One hundred and forty plants species perform well under the local environment, showing a good adaptability. However, some plants are prone to lodging and susceptible to diseases and insect pests. There are 157 kinds of plants of high ornamental value, mainly for their flower and foliage and rarely for their stem and fruit. Their florescence mostly occurs in spring, summer or autumn, especially in summer. Besides, there are 90 kinds of evergreen plants. There are 161 kinds of plants which are safe for application. However, there are some species that are poisonous or easy to spread. The analytic hierarchy process (AHP) is used to give a comprehensive evaluation of the flower border plants, and 52 kinds of evergreen plants with high ornamental and application value are selected, of which the ones with a comprehensive score of 3. 5 or more can be popularized and utilized on a large scale
