Considering the ever-increasing state of pollution in different aspects of the environment, ornamental plants and herbs such as Lavandula have become the center of attention mostly due to their availability and use in urban green spaces. Phytoremediation is a modern and economical method which can be applied to metropolises for decreasing metal contaminations in soil, water, and atmosphere. This study examined the contamination resistance of Lavandula against cadmium through 3 completely randomized block design experiments. The treatments included cadmium at 2 concentrations (0 and 100 mg) and DTPA at 2 concentrations (1 and 2 mM). Results suggested that heavy metal stress decreased morphologic properties under study and by adding DTPA the cadmium absorption decreased in Lavandula.
