This vernal community is dominated by Cardaria draba, a perennial herb forming dense polycorms. It occurs along railways and roads, in disturbed lawns in human settlements and industrial zones, orchards and vineyards, on field margins and in waste places. The stands are usually found on sunny sites with dry soils of intermediate nutrient status. After the period of maximum biomass and flowering in May and June, Cardaria draba polycorms die back. In the Czech Republic this vegetation type occurs in warm lowlands and colline landscapes.
