Q: Chinese privet is a plant that is native to china. Over 150 years ago, Chinese privet
was introduced to the United States as a fast-growing shrub that serves as an excellent
privacy hedge. with no natural predators, Chinese privet quickly established itself and
spread in natural areas throughout the southeast and eastern seaboard of the United

high for the few individuals that survive to a certain age.
