Cotoneaster dammeri (Bearberry Cotoneaster) is a fast-growing, evergreen groundcover noted for its dense, low-lying foliage, bright red berries, and petite white flowers that appear in late spring.
It can reach a height of about 12 inches (30 cm), and spreads up to six feet (1.8 m).
The plant's sprawling habit and ornamental berries make it a popular choice for slopes, banks, and rock gardens.
It's hardy in USDA zones 5 to 8, and thus to RHS zones H6 (-20 to -15°C).
How to Grow Cotoneaster dammeri in the Garden
Cotoneaster dammeri is quite versatile and can grow in full sun to partial shade.
The plant adapts to a variety of soil types, but prefers well-drained soil. It tolerates soil pH from mildly acidic to mildly alkaline.
Planting can be done in spring or autumn. Dig a hole at the depth of the root ball, and about twice as wide. Next, place the plant in the hole, backfill with soil, and finally water thoroughly.
Regular watering is appreciated, particularly during the first growing season as this will help to establish a strong root system.
Once it is established, it will tolerate drought, but it does prefer consistent moisture. Applying a general-purpose fertilizer in spring encourages healthy growth and blooming.
Minimal pruning is required, but it can be pruned in late winter or early spring to better shape it, and to control its spread.
While generally disease-resistant, Cotoneaster dammeri can sometimes be affected by fire blight, leaf spot, or canker.
Adding Cotoneaster dammeri to your garden can provide an excellent ground cover, a flurry of spring flowers, and vibrant berries, thus creating year-round visual interest with minimal maintenance.
