This vegetation type is dominated by Sisymbrium officinale and includes some other annuals and species of trampled habitats. It is found on sunny to slightly shaded sites, most often in village yards, in gaps between city buildings, and on roadsides and dumping grounds. Soils are loamy, with good availability of moisture and nutrients. Sisymbrium officinale is a winter annual which reaches its maximum biomass in July, but it persists until autumn. It is common from lowland to submontane areas of the Czech Republic.
