Rhamnus saxatilis, commonly known as Rock Buckthorn or Stone Buckthorn, is a deciduous perennial shrub native to rocky hillsides, screes, and woodland margins across Europe and Western Asia. It typically grows at a moderate rate to a height and width of 1.5-2 feet (0.46-0.6 meters), forming a dense, rounded shape. The plant features small, greenish-yellow flowers that bloom in late spring, followed by red to black berries that are attractive to birds. The leaves are small, oval, and have a leathery texture with a glossy surface.

Rock Buckthorn is valued for its ability to thrive in challenging conditions, including poor soils and rocky terrains. It is often used in rock gardens, as a low hedge, or for erosion control on slopes. This shrub is also appreciated for its wildlife value, providing food and shelter for various bird species. It requires minimal maintenance once established, tolerating drought and a range of soil types, though it prefers well-drained clay, loam, or sandy soils. It can be grown in full sun to part shade, with medium water requirements. While generally disease-resistant, it can occasionally suffer from leaf spot or aphid infestations.CC BY-SA 4.0
