Ligustrum — commonly called privet–is one of the most widely used hedge plants. Ligustrum are grown for their foliage and flowers. Besides hedging, Ligustrum can used in shrub borders and as a background plant.

Ligustrum bear showy clusters of white to creamy white flowers in late spring or early summer. Clipped hedges bear fewer flowers since shearing removes most of the flower-bearing branches. Blossoms are followed by small, berrry-like blue-black fruits.

Ligustrum is a genus of about 50 species of deciduous and evergreen shrubs and trees. About 10 of the species are commonly used as hedges and screens.

Ligustrum Varieties to Grow 

  • Ligustrum amurense, Amur privet, good for cooler regions, Zones 3 to 7 or 8, a deciduous Chinese species, grows 10-12 feet (3.1-3.7m). It can withstand heavy pruning.  
  • L. japonicum, Japanese privet, a compact evergreen, slow-growing species, and a favorite; grows to 12 feet (3.7m) tall and usually 8 feet (2.4m) wide, with thick, shiny, rounded 2-4 inches (5.1-10.2cm) leaves, paler underneath. Pyramid-shaped panicles of heavily perfumed white flowers bloom for several weeks in midspring. Popular for southern gardens, sometimes pruned as a tree. The dark berries are flat and waxy. Cultivars include variegated and curly-leaved forms. Grows in warmer regions, Zones 7 to 9. 
  • L. lucidum, Glossy privet, evergreen tree. Makes a round-headed tree that eventually reaches 35-40 feet (10.7-12.2m). Can be kept lower as a big shrub or may form a multitrunked tree. Glossy, 4-6 inches (10.2-15.2cm) long leaves are tapered and pointed, dark to medium green on both sides feel leathery but lack the slightly spongy feel of L. japonicum’s leaves. Flowers in especially large, feathery clusters followed by a profusion of fruit.; can grow in narrow areas; good street tree if not planted near pavement or where fruit will drop on cars. Performs well in large containers. Or plant 10 feet (3.1m) apart for tall privacy screen. Useful as windbreak.  
  • L. obtusifolium, Border privet, a deciduous, multi-stemmed, twiggy shrub to 12 feet (3.7m) tall and wide. The leaves often turn purple in fall, and the early to midsummer flowers nod from side branches. L. o. var. regelianum (Regal privet) is even more strongly horizontal, with hairier leaves that are held in a flat plant. Zones 4 to 7.   
  • L. ovalifolium, California privet, a vigorous large shrub originally from Japan, 10-15 foot (3.1-4.6m), works well for hedges. Its glossy green leaves last almost year-round in Zone 6; in Zones 7 and 8, it is an evergreen. In summer it bears clusters of creamy why flowers followed by black fruits. Zones 5 to 8.  
  • L. vicaryi, Vicary golden privet, deciduous shrub. This one has yellow leaves; color is strongest on plants in full sun. Grows 4-6 feet (10.2-15.2cm) high, possibly to 12 feet (3.7m). Best planted along; color does not develop well under hedge shearing.  
  • L. vulgare, Common privet, deciduous shrub. Grows to 15 feet (4.6m) unsheared. Dark green leaves less glossy than those of L. ovalifolium, root system less greedy. Clusters of black fruit conspicuous on unpruned or lightly pruned plants. ‘Lodense’ (‘Nanum’) is a dense dwarf form that reaches only 4 feet (1.2m) with equal spread.
