Introduction Last years the has been developed new assortment of decorative  plants for green building of republic which distinguish with high-decorative qualities, hardy in our conditions. By means of decorative plants  is possible to create various landscape compositions, as leaf-bearing decorative and coniferous.  The coniferous trees and bushes get the increasing popularity in modern greenery design (1). Material and methods For  number of the  years in dendrary are introducted  more than 60 species and 15 forms of coniferous plants which belong to 14 sorts and 9 families. The basic volume is made by species Pinus L. (17,5 %), Juniperus L. (16 %), Chamaecyparis Spach. (14,5 %), Cupressus L. (9,3 %).  We study the bioecological features, decorative and ways of adaptation of these species to establish their perspectivity in the conditions of Absheron on purpose to use in landscape design (2,3). Results and discussions Long-term research have shown that the basic coniferous plants well grow and develop in dry subtropical conditions of Absheron. These species are from sorts: Chamaecyparis Spach., Cupressus L., Juniperus L., Thuja (L.) Tourn., Pinus L., Taxus L. The species from sorts Picea Dietz. grows very weak. For creation interesting and durable compositions are necessary for using decorative coniferous which distinguish the form of the crone and needles colouring (Chamaecyparis optusa Sieb.et Zuss. f.”aurea”, Juniperus virginiana L. f.”glauca”, Thuja occidentalis L. f “aureo-variegata”, Pinus pumilio (Pall.) Regel  f.”mugo”). In the  dendrary the last  years was introducted new species and forms:  Araucariya araucana C.Koch., Cunninghamia lanceolata Lamb., Juniperus depressa Stev., Microbiota decussata Kom., Picea orientalis Link. f.”aureospicaba”, Taxus baccata L. f. ”festigiata”, Cycas revoluta Thunb. etc. For border creation  is possible to use dwarfi sh species and forms coniferous: Juniperus chinensis L., J.sabina L., Thuja occidentalis L.f. ”compacta”  etc. All species and forms have been located on systematiko - landscape by principles and it  is the basic genofund  of dendrary. Conclusions The results research gives us possibilities to use in greenery of Absheron highdecorative species and forms  of coniferous  plants ( Chamaecyparis Spach., Thuja occidentalis L., Cycas revoluta Thunb., Cupressus arizonica Greene, Cryptomeria japonica Don., Juniperus polycarpos C.Koch.,) etc.
