This is a thermophilous and nutrient-demanding vegetation type dominated by the winter-annual herb Anthriscus cerefolium. It occurs along roads and paths, in fringes of scrub, black locust groves, ravine forests and at the bases of shaded walls. Habitats are usually shaded, with nutrient-rich soils which are mesic in spring but dry out in summer. Anthriscus cerefolium stands produce maximum biomass in May, but they die back in June. Localities of this association are scattered in the warm areas of the Czech Republic.
