Ligustrum japonicum, Japanese privet, is a tough, evergreen shrub often used as hedges, screening, and topiary. You will find facts and information on growing and caring for Ligustrum japonicum and how to use them in your landscape.
Japanese privet is a tough low-maintenance shrub that grows in Zones 7-10. It may also be referred to as Ligustrum japonica. The shrubs will grow 6-12’ h x 6-8’w. It is extremely tolerant of a wide variety of soil conditions. The leaves are opposite, evergreen, with sharp terminal points, and slightly pear-shaped.
White flowers are borne on large terminal panicles, followed by dull black berries that persist most of the year. They are a source of food for birds when other berries or food sources are scarce. This helps it to naturalize but unfortunately disperses the plant and makes it invasive. Also worth mentioning, is the fact that flowers do not have a pleasant scent.
