This weed community from the alliance Eragrostion cilianensi-minoris is dominated by Hibiscus trionum growing on fields with various crops (cereals, sunflower, suger beet or maize), on stubble fields and in field margins. Soils are usually clayey, poorly drained and slightly saline, in places developed on former saline grasslands and occasionally flooded. This vegetation develops at the end of spring and its phenological optimum is in late August/early September. In the Czech Republic this community has been recorded at only a few sites in southern Moravia.
