This association includes open stands of annual vegetation with Chenopodium botrys, which occur on well drained substrates such as dross, gravel or sand heaps, railway tracks, sand pits and spoil heaps. The phenological optimum of this vegetation type is in late summer. In the Czech Republic several stands have been documented in lowland and colline areas.
