Gall-berry is a term used to describe a type of evergreen shrub that is native to the southeastern region of the United States. While the term gall-berry is commonly used, there are several other synonyms that can be used to describe this plant. These include inkberry, swamp holly, and evergreen winterberry. All of these terms refer to the same shrub and are all interchangeable. The plant is known for its dark green, glossy leaves and the small, round berries it produces. The berries are often eaten by birds and other wildlife and are an important source of food in the winter months.
