This study was carried out in 2016 to determine the morphological characteristics of the Thymbra spicata L. var. spicata in Siirt Flora. The morphological characteristics of the plant from different aspects (north, south, east, west) and in different developmental stages (before flowering, after full bloom and after flowering) were investigated. The plant samples were collected according to divided parcels in randomized complete blocks design with 4 replications. In the study, different aspects (north, south, east, west) formed the main plots and different developmental stages (before flowering, after full bloom and after flowering) formed the subplots. In the research, while the effects of different aspects and developmental stages on the leaf width were not statistically significant; The effect on plant height, stem thickness, number of flowers, calyx height, petal length and pedicel length were found statistically significant. As a result, it is thought that it would be beneficial to conduct similar studies both in this species and other species of economic value collected from nature.
