Descurainietum sophiae

Photo on

This association is formed of stands of Descurainia sophia, accompanied by other tall annuals. It occurs in warm and sunny places on rubble of demolished buildings, rubbish heaps or tops of old walls. It is a vernal community that can be found until June. On certain sites it usually lasts for no more than two seasons, then giving way to perennial ruderal vegetation. In the Czech Republic it occurs mainly in colline areas.
