Kish Island is located in the Persian Gulf on the mainland Iran. Salinity and the use of low quality water affect the ornamental aspects of species. Plants in Kish Island irrigated by low quality water face with salt and drought stress. The purpose of this study was to analyze the performance of Tecoma stans (L.) Juss. ex Kunth, Euonymus sp., Conocarpus erectus Jack, Ficus benjamina L., Ficus bengalensis L., Melia azadirachta L. and Delonix regia (Boj. ex Hook.) Raf in four different regions (Sanaie, Sadaf, Pavion and Saffain) of Kish Island regarding the growth, development and ornamental characteristics. During the assay, March-September, the plant height, leaf area, leaf number, chlorophyll and proline content, stem diameter and height, and dry and fresh weight of leaf were measured twice. C. erectus and F. bengalensis were recommended for the considered regions in Kish Island. Furthermore, D. regia was ideal for Sadaf and Pavion regions. This study may be useful in selecting suitable species for the same situation as these different regions in Kish Island.
