This community is dominated by Lycium barbarum, an alien shrub of Asian origin. Interior parts of the stands contain considerable amounts of dry Lycium branches. The herb layer is characterized by both perennial and annual ruderal species. It occurs on dry, sun-exposed sites in warm lowland and colline landscapes, e.g. on vineyard terraces, railway rights-of-way and road banks or along fences and walls. At higher altitudes it is confined to urban habitats. The soils are usually calcareous and well drained. Some stands were planted to prevent soil erosion.
