The article has already been present scientific material on the introduction and definition of biological and ecological potential of a little common vegetable plant family Asteraceae biennial species. Salsify (Tragopogon porrifolius), Chicory rhizocarpous (Cichorium intybus L. var. Sativum Lam.) and perennial Chicory vitluf (Cichorium intybus L. var. foliosum Hegi), Chicory endive and escarole (Cichorium endivia L.), Artichoke sowing (Cynara scolymus L.) and Wormwood tarragon (Artemisia dracunculus L. Oligosporus dracunculus L. Poljak). Already been provide health and preventive features of each species. Their yield of marketable products and seeds, analysis of biochemical components. In terms of the dry matter content of plants up to 28.5% and total sugar up to 14.6%, the oat root was already distinguished and for ascorbic acid up to 200.0 mg/100 g - wormwood tarragon. The distribution of plant species has already been carry by reaction to the average daily air temperature during the period of seed germination, the growth of perennial plants after wintering, and optimum temperatures during the period of growth. Noted that the plant species were cold resistant and require a small amount of moisture. The results of studies on the ratio of plants of the wormwood tarragon species to the effect of the sum of active temperatures and precipitation for 2006–2016 have already been present. Found that with increasing amount of precipitation by 1%, the yield of plants of wormwood tarragon increased by 0.01–0.02 t/hа. At the same time, it ware pointed out that, behind the hydrothermal coefficient (SCC), the highest yield of 19.00–19.70 t/ha was in 2006 with a SCC – 1.48, 2009 with a SCC - 0.98. This characteristic is for plant species registered in the State Register of Plant Varieties suitable for distribution in Ukraine and the new stable variety Unenezh. Exceeded the local form in yield by 82 t/ha and is distinguished by a powerful rosette of plants
