1 000 wild plants common in Hubei Province were used as a candidate pool to establish a model of evaluating the potential of utilizing garden plants by setting up 21 indexes of evaluation and developing rules for classifying the potential of utilization to promote the development and utilization of wild plants in Hubei Province，and solve the problem of insufficient utilization of indigenous plants in urban gardens. The results showed that 172 species of plants were classified as gradeⅠ，which can be directly utilized and serve as the preferred choice for enriching the utilization of indigenous plants in gardens and green spaces in Wuhan City based on comprehensively evaluating the target layer of the potential of utilizing garden plants. 331 species of plants were classified as gradeⅡ，can be recommended for use in various scenarios and is a good resource for effectively expanding the scope of utilizing wild plants in Wuhan City. 291 species of plants were classified as gradeⅢ，with multiple constraints for the direct utilization and should be used cautiously under specific conditions. 206 species of plants were classified as gradeⅣ，difficult to meet the requirements of utilization in gardens and not recommended for the direct use in gardens. According to the special evaluation of the principal layer under the target layer，plants with strong adaptability to environment include Farfugium japonicum and Lespedeza thunbergii subsp. formosa. Plants with high capacity of ecological service include Fraxinus insularis and Pistacia chinensis. Plants with high ornamental value of landscape include Cornus controversa and Rosa omeiensis. Plants with high potential of environment-friendly include Cornus officinalis and Rubus hirsutus. Plants with high potential of utilization and extension include Macleaya cordata and Rehmannia piasezkii. It is indicated that wild plants in Hubei Province have high potential of development and can be introduced and utilized based on the results of evaluation.
