Green space development a critical need for today’s life style in the grand cities, however concerns on water shortage is from the main constraints against such developments. Native plant species naturally grow in the urban counties, only by using the rainfed irrigation. Therefore, less water would be used if we domesticate and introduce native plant species into the urban green spaces. Seeds and propagules of Eurotia ceratoides, Kochia prostrata, Slasola rigida, and Iris songarica were collected from their natural habitats in Khorasan Razavi Province. They were sown at March 2015, and were grown during two growing seasons in spring and summer of 2015 and 2016. Establishment rate, phenological stages and morphological traits of the established plants were measured and recorded for two consecutive growth seasons. Highest seedling mortality rate was found in the first three months after the cultivation. The most and least establishment rates were respectively found for Iris and Zygophyllum, respectively being 85% and 17.5 %. Evaluating the irrigation requirement indicated about 52% water conservation and 50 million rials/ha money conservation, in the case of sowing native range plant species, as compared to a common green space shrub (Ligustrum vulgare). Applied information is provided on the best time of sowing, reproductive organ, ornamental value, irrigation times per month, and tillering requirement and the best places for cultivation of the six plants of this study.
