Water shortages has always been a great concern as a limiting factor for agricultural production in Kerman province. Rainfed sowing may be recommended to bypass the problem. Because of high rates of potential evapotranspiration and limited water resources in arid and semiarid areas, it is expected more attention will be paid to study of the effects of rain fed culture on quality of medicinal plants. In order to investigate the establishment, growth and yield of some of perennial medicinal plants (Thymus caramanicus, Elaeagnus angustifolia, Olea europaeain, Thymus vulgaris, Rosa damascena, Thymus daenensis, Artemisia persica, Ferula assa feotida, Glycyrrhiza glabra, Rosmarinus officinalis, Lavandula officinalis, Salvia officinalis, Achillea millefolium ), the study was conducted using a randomized complete block design (RCBD) with 3 replications during 3 years from 2012 to 2014 in the Kohpanj mountains in the west of Bardsir city. During the growing seasons, the phonological and morphological events were recorded and finally analyzed by SAS software and the means were compared using Duncan's Multiple Range Test at 0.05 level. The results showed Thymus caramanicus, Elaeagnus angustifolia and Olea europaeain destroyed in the first summer because of environmental drought. Thymus vulgaris, Rosmarinus officinalis, lavandula officinalis, Achillea millefolium and Salvia officinalis Survived in the first year, but destroyed in the second year. Rosa damascena (85%), Thymus daenensis (60%), Artemisia persica (77%), Ferula assa feotida (100%) and Glycyrrhiza glabra (100%) had the most survival rate among the species. With aging, dry weight of the plants were increased. The greatest dry weights were in Thymus daenensis, Artemisia persica and Ferula assa feotida respectively equal 188, 135.6 and 16 g/m2. The greatest dry weight of root in Glycyrrhiza glabra (173.3 g/m2) obtaind in the third year. The most number of flowers in Rosa damascena (31 flowers per plant) obtained in the third year.
