Data on the dynamics of the ontogenetic structure of one coenopopulation Jurinea cyanoides (L.) Reichenb.are presented for the period 2014–2019 due to environmental conditions. It is shown that the efficiency of the development of ecological space is the highest in terms of climate continentality and thermoclimatic factors, the lowest in termsof soil moisture and acidity, ombroclimatic aridity-humidity. The ontogenetic spectra are uniform over the years: the maximum fall on individuals of the juvenile, virginal and subsenile ontogenetic states, and the minimum is on the plants ofthe generative period in aggregate. According to the «delta-omega» classification, the studied coenopopulation undergoesdevelopment from young to transitional.
