This paper aims to determine the potential for using medicinal aromatic plants, which have been considered living heritage since prehistoric times, in urban landscapes. The area of study covers Malatya City and its counties, which are found in Eastern Anatolia, a region of importance in terms of the endemic species in Turkey. Malatya is specifically selected as the study area, as the city's geomorphological, hydrological and climatic characteristics favour a high floral diversity. The methods used in this paper consist of five stages: floristic field works conducted in Battalgazi county (Malatya) in the scope of the Scientific and Technological Research Council of Turkey (TUBITAK) Project No. 217O290, the identification of the plants by a taxonomist, the determination of the medicinal and aromatic species in other counties of Malatya based on literature review, the establishment of criteria for the application potential of the identified species in landscape designs and the assessment of the use of the identified species in landscape architecture according to the parameters set in the criteria. Aromatic medicinal species were analysed to generate planting designs in landscape projects; the aesthetic properties (flower, leaf and fruit characteristics), sensory properties (scent and texture), seasonal change characteristics (flowering period and colour change) and use areas (flower parterres, solitary plantings, live fences and site coverings) of the plants were analysed. As a result of ethnobotanical and floristic studies carried out within the boundaries of the study area, a total of 189 medical aromatic species were identified. A total of 157 of these species were herbaceous plants. In conclusion, it was determined that 80 aromatic medicinal species conform to the planting design criteria and could be used in landscape designs in Malatya City.
