Ligustrum is a genus of around 50 species of deciduous or evergreen shrubs and small trees in the Oleaceae family. This genus is native to Eurasia and Africa with many species now naturalised in non-native habitats around the world. Members of the genus have simple leaves and panicles of tiny usually white flowers that are followed by black berries. In some species, these flowers smell unpleasant. Commonly known as Privet, they are often cultivated as hedging plants as they are hardy and take well to clipping and pruning.
