In order to maintain sustainability for landscapes in the arid region, the use of native plants is of considerable importance, in the light of the fact that the exotic plants currently used do not resource efficient. The native plants adapted to the harsh environment of the desert ecosystem could play a critical role in this direction where the natural resources could be sustainably used. Research on evaluation and analyzes of native plant species of the UAE for potential application in landscapes have been considered. The present investigation reports the results of the exploration of native plants suited for sustainable landscape for resource efficiency. It also encompasses the study about the response of native grass species identified in the survey and the shrubs to varying levels of irrigation. Further, the germination responses of selected plant species, tissue culture propagation of endangered tree species and their long-term conservation strategies were also part of the study. During plant exploration, 61 plants were identified with potential for landscaping out of which, based on further evaluations with specific landscape qualities, 30 plant species of different forms were recommended for future landscape use. A native grass Digitaria spp. was identified, which was found to have the potential to be used as ground covers in arid landscapes, compared with four nonnative grass species. The analysis and confirmation of stabilized responses for drought tolerance were done based on morphological responses, elemental status and antioxidant enzyme mechanisms operating under wider frequency of irrigation. In 9 selected shrubs and one grass species, irrigation experiment was conducted with a constant irrigation volume under four different frequencies. The responses to induced drought were assessed based on the morphological parameters, macro and micronutrient status that can influence the growth and development. The seeds of fourteen plant species were subjected to germination responses after exogenous application of gibberellic acid at 400 mg/l and 200 mg/l to accelerate germination, where many of the desert species are recalcitrant. The mean germination time (MGT) was shorter, where higher germination is noticed. In vitro propagation protocols were standardized in 3 endangered tree species viz., Moringa peregrina, Haloxylon persicum and Acridocarpus orientalis by direct organogenesis as part of in vitro conservation and faster multiplication. Long-term storage employing cryopreservation by vitrification and desiccation method was accomplished in the above three species. Based on the findings of this study, it can be concluded that the use of native plants of the UAE for landscape applications could create resource efficient, sustainable landscaping
