Report an issue with this species
Rhamnus, commonly known as Buckthorn, comprises shrubs to small trees with glossy, often evergreen leaves and inconspicuous greenish-cream flowers. Many species are adaptable to various climates, including Mediterranean, and some produce red to black berries that can be toxic. While some are valued for their ornamental foliage and use in reforestation, certain species are highly invasive in coastal and forest ecosystems due to their rapid growth.
