Chromium is a heavy metal that is toxic to plants and other living things. It is known that plants can be used to remove heavy metals from the environment if they accumulate in the soil. Various ornamental plants are used in urban areas due to their decorative properties. In this study, the effectiveness of the Bad-Birnbach rose variety in removing excess chromium in the soil was investigated. To determine its effect on the vegetative and generative development states of roses and Cr uptake from the soil, different doses of Cr+6 (0, 25, 50 mg/kg soil) and 0-5-10-20 mmol EDTA were applied to the plant growth medium. At the end of the experiment, the dry weight of the stem and root decreased significantly with the applications of Cr+6. With EDTA application, the dry weight of roots and flowers increased. Cr concentrations in stem, root and rose are between 3.63-55.04, 14.53-314.77 and 2.31-13.44 mg/kg, respectively. Cr concentrations in the plant are above the permissible limit values and Cr+6 has accumulated significantly in the root zone.
