Botanical Overview: The Genus *Cotoneaster*
Belonging to the Rosaceae family, the genus Cotoneaster comprises over 250 species of deciduous and evergreen shrubs and small trees. Their leaves vary from small and glossy to larger and matte, often turning fiery shades of red, orange, or purple in autumn. In spring and summer, cotoneasters produce clusters of small, white or pink flowers, which give way to vibrant red, orange, or black berries (pomes) in late summer and autumn. These berries are a vital food source for birds, enhancing their ecological value.

- Known as the “rock cotoneaster,” this species forms a low, spreading shrub with herringbone-patterned branches. Its white flowers and bright red berries make it a striking ground cover or wall plant.
Cotoneaster franchetii
- An evergreen to semi-evergreen shrub with dark green, glossy leaves and masses of pink flowers followed by scarlet berries. It’s ideal for hedges and wildlife gardens.
Cotoneaster dammeri
- Commonly called “Bearberry,” this low-growing, evergreen shrub is perfect for ground cover. Its small, dark green leaves turn bronze in winter, and its red berries persist through the cold months.
