Iran is one of the countries placed in arid and semi-arid areas. Using endemic perovskia (Perovskia spp.) in the urban landscape helps in optimizing the amount of water in the irrigation. In addition, due to their compatibility with the country climate, high drought resistance and attractive flowers, provides suitable field for achieving the sustainable landscape development. This study was laid out to introduce different varities of perovskia, which are suitable for urban landscaping of dry and semi dry areas. Therefore, perovskia plants were collected from three regions in Isfahan, khorasan and Markazi provinces and their tolerance to drought stress was evaluated in four levels (25%, 50%, 75% and 100% of field capacity) in three different species of perovskia (P. atriplicifolia, P. artemisioides & P. abrotanoides). Results indicated that drought stress increased proline, catalase, peroxidase, ion leakage and reduced chlorophyll and carotenoids. Although, due to drought stress, morphological parameters (plant height and diameter, shoots number, leaves number and plants fresh and dry weight) was decreased. Between three species, P. atriplicifolia showed the highest indexes in case of morphological and physiological parameters in drought stress condition. According to the results, we can introduce endemic perovskia, which is a less known plant, as a suitable drought tolerant plant for urban landscape.
