Nevertheless, there are sufficient studies on the landscape application of native plants. There is an abundant resource of Ilex plants in Dinghu mountain, the majority of which has not yet been exploited. Based on the filed investigation of 25 wild Ilex plants, the study analyzes their germplasm resources, habitat storage and ornamental characteristics, and aims to put forward some constructive suggestions in the introduction and application of the Ilex plants in Dinghu mountain, including enhancing the biological and application research of local landscape to bring the landscape into full play, improving the quality of landscape application, promoting the ecological garden city construction and integrated application.
