© Forestist 2022.Deciding on plant species when considering planting design in landscape design studies is a complex phenomenon. Considering the planting designs implemented, especially in urban areas, it is observed that exotic species are used instead of the species that grow naturally in the region, and compositions that are not suitable in terms of design elements, principles and functions are created. For this reason, our aim in this study is to determine the effective plant characteristics in the preference of plants and to reveal which characteristics come to the fore. The plant characteristics that emerged as a result of the research were collected under five main groups: urban tolerance, landscape effect, regenerative characteristic, functional characteristic, and economic characteristic; and under 29 subgroups. In our study, the scoring method was used for selection criteria on 218 plant species grown in the Eastern Black Sea coastal areas, and the numerical data obtained from the scores were evaluated by factor and cluster analysis with the SPSS 16.0 program. Urban tolerance and landscape effect selection criteria came to the fore in the application-oriented designs of these plants growing on the Black Sea coast, and species such as Tilia rubra DC, Aesculus hippocastanum L., Elaeagnus angustifolia L., Eucalyptus camaldulensis Dehnh., and Juglans regia L., ecologically pleasing, and esthetically enriching the place, were found to have the highest score.
