This plant is listed as a noxious weed in one or more Midwestern states outside Missouri and should not be moved or grown under conditions that would involve danger of dissemination.


Easily grown in average, dry to medium, well-drained soils in full sun to part shade. Tolerant of a wide range of soils, except wet ones. Tolerant of urban conditions. Prune as needed immediately after flowering. If flowering is not a consideration, prune in spring. Hedges are also commonly trimmed 1-2 times in summer. Plants will naturalize by self-seeding in optimum growing conditions, and may form thickets in areas where growth is not controlled.

Noteworthy Characteristics

Ligustrum obtusifolium, commonly called border privet, is a fast-growing, deciduous shrub that typically grows 10-12’ tall but spreads to 15’ wide with dense, often arching, horizontal branching. It is winter hardy to USDA Zone 3, and is perhaps the most commonly grown privet in northern parts of the U. S. Elliptic to oblong-obovate, glossy, dark green leaves (to 2.5” long) have hairy midribs beneath. Leaves may acquire attractive purple tones in fall. Small, tubular, white flowers in nodding panicles (to 1.5” long) bloom at stem tips in June. Flowers are fragrant, but are considered by many to have an unpleasant aroma. Flowers give way to globe-shaped drupes which ripen to dull black in fall and persist into winter.

Genus name comes from the Latin word for privet.

Specific epithet means blunt-leaved.


No serious insect or disease problems. Some susceptibility to a number of potential disease problems, including anthracnose, crown gall, twig blight, leaf spots, powdery mildew, cankers and root rots. Aphids, leaf miners, scale, thrips, mealybugs, whitefly, nematodes, Japanese beetles, weevils and mites may appear.


This shrub is noted for forming an excellent hedge, screen or background planting. Shrub border.
