This association includes both open and closed Sesleria caerulea grasslands occurring on north-facing cliffs and rocky slopes which are more humid and cooler than habitats of the other associations of the alliance Diantho lumnitzeri-Seslerion. This association also contains more species of higher altitudes. It occurs on limestone and base-rich siliceous bedrocks in the Bohemian Karst and adjacent areas of central Bohemia, at some isolated sites in the dry area of northern Bohemia, in the Moravian Karst, south-western Moravian river valleys and the Pavlovské vrchy hills in southern Moravia.
