In recent years, the Araliaceae plants have been widely used in the planning of urban garden and road green space. China is rich in Araliaceae plant resources and Araliaceae plants are outstanding in form, but their ornamental value is less studied. Through the statistical survey of the germplasm resources of Araliaceae plants in southeastern Tibet, and the research and analysis of their functions and ornamental characteristics, this paper concluded that the Araliaceae plants in southeastern Tibet have high ornamental value, and 12 varieties of Araliaceae plants can be used in gardens and have great research and development significance. Finally, it came up with recommendations for the collection and protection, introduction and breeding, and garden application of Araliaceae plant resources.
