False Buckthorn is a shrub native to Europe that has become invasive in many parts of North America. This plant has many synonyms, including Alder Buckthorn, Glossy Buckthorn, and Dogwood Buckthorn. False Buckthorn has slender branches with thorns and glossy leaves that turn yellow in the fall. It produces small green flowers in the spring that turn into black berries in the fall. False Buckthorn is often confused with other similar plants, such as Common Buckthorn and Sea Buckthorn, which are also invasive and have similar characteristics. It is important to properly identify False Buckthorn and other invasive species to prevent them from spreading and damaging local ecosystems.
