Ligustrum vulgare is established across the eastern U.S. and in scattered western states. It is a stout and much branched shrub up to 5 m tall that is widely used as a hedge. Ligustrum vulgare is extremely agressive and escapes from cultivation. It forms dense and impenetrable thickets that crowd out native species. Apparently, it often occurs in disturbed situations but may also occur in more intact vegetation such as river bottoms, closed canopy forests, and calcareous glades and barrens.Ligustrum vulgare is a prolific seed producer. At Indiana Dunes National Lakeshore it produces more than 1000 seeds per plant. Birds can spread seeds far from the orginal planting. Ligustrum vulgare also colonizes by root sprouts. Once established, Ligustrum vulgare is difficult to control (NatureServe 2007).
