Ligustrum lucidum

Glossy privet

Nonnative to FloridaFISC Category 1 Invasive

Species Overview

There are about 50 species of Ligustrum, all native to Europe, North Africa, and Asia. Ligustrum has been developed into an assortment of ornamental varieties in the U.S. and other parts of the world. In 1852, privet was introduced to the United States for use as an ornamental shrub and is still commonly used as a hedge. Because of Ligustrum’s ability to tolerate air pollution and other poor environmental conditions, it was regarded as a great landscape plant and planted extensively. Unfortunately, this was before its invasive characteristics were discovered. Establishment of privet in many natural areas of Florida has occurred through its escape from cultivation. Glossy privet (L. lucidum) is listed as a Category I species with the potential to disrupt native plant communities in Florida by the Florida Exotic Pest Plant Council. Chinese privet (L. sinense) is a Category I species that is currently disrupting native plant communities in Florida.

Species Characteristics

Ligustrum spp. are perennial shrubs that can grow up to 16 feet in height. Ligustrum bark is tan to gray in color with a smooth texture. Leaves are elliptic to ovate in shape, oppositely arranged on twigs. Flowers have both male and female parts. Each flower has petals fused into a tube with four separate lobes. Flowers are borne on small panicles on short lateral branches on the end of the twig. The oblong, blue/black fruit is a drupe containing 1 to 4 seeds. Fruit clusters persist through the winter. Mature trees can produce hundreds of fruit.


Ligustrum spp. is capable of invading natural areas such as floodplain forests and woodlands. The aggressive nature of privets allows for the formation of dense thickets that out compete desirable plants. The amount of seed produced by privet is another mechanism for its prolonged survival. Even though privet is still used in the landscape and available for purchase at garden centers and online distributors, it is an invasive weed and should be treated as such.

Control Methods

Preventive Measures

The first step in preventative control of privet is to limit planting and removal of existing plants within the landscape. If possible, removal should occur before seeds are produced. Since seeds remain on the plant for several months, care must be exercised to prevent seed spread and dispersal during the removal process.


Plant native or non-invasive alternatives. Avoid large disturbances that allow for invasive species to colonize.


For smaller infestations or areas where herbicide applications are not feasible mowing and cutting are appropriate. Stems should be cut as close to the ground as possible at least once per growing season. Mowing and cutting will not eradicate Ligustrum spp., but it will provide some level of management. Continuous mowing will work, but frequency is key.


Ligustrum spp. has no known biological control agents.


Foliar applications of glyphosate or cut-stump applications of triclopyr or glyphosate are effective. Stems <0.5 inch diameter are susceptible to basal bark applications of 20% triclopyr-ester (Remedy) in oil. Larger stems must be notched or frilled.
