This low-growing vegetation type dominated by annual Veronica species occurs in winter cereal fields, vineyards and recent fallows, as well as on exposed loamy soils outside agricultural habitats. It develops from mid-March to mid-May before the crop or taller weeds form dense stands. After May it is replaced by other Caucalidion associations in arable habitats or by stands of taller annual herbs in ruderal habitats. It is concentrated in warm and dry areas of the Czech Republic, but also occurs in some cooler parts of the country.
