This alliance includes ruderal vegetation types dominated by tall perennial, nutrient-demanding dicots with C or CR strategy. It occurs in both villages and cities, particularly on dumping sites, building rubble, disturbed sites around water courses or bodies, roadsides and vegetated strips along walls and fences. Soils can be either slightly wet or dry, and correspondingly species composition includes mesophilous or xerophilous species; in the syntaxonomical classification system this vegetation type is transitional between the classes Artemisietea vulgaris and Galio-Urticetea.
