Cotoneaster horizontalis 'Variegata', also known as Variegated Rock Cotoneaster, is a low-growing, spreading deciduous shrub that features striking variegated foliage and a dense, spreading habit. The leaves are a mix of green with cream or white edges, offering a bright contrast that adds visual interest to the landscape. In the spring, small white flowers appear, followed by red berries in the fall, which are highly attractive to birds. The branches of this cotoneaster spread horizontally, creating a natural cascading effect that is perfect for use as ground cover, or on walls, slopes, and in containers. Its variegated leaves and seasonal berries provide year-round interest, making it a versatile and ornamental plant for various garden designs.
Cotoneaster horizontalis 'Variegata'
- Light: Prefers full sun to partial shade. For the best color contrast in its variegated leaves, full sun is ideal. It can tolerate some shade but may lose some of its vibrant variegation.
- Watering: Water regularly during the growing season, especially in dry periods. Once established, it is relatively drought-tolerant, but occasional deep watering can help maintain its health and vigor.
- Soil: Grows well in well-draining, moderately fertile soil. It is adaptable to a variety of soil types, including sandy and rocky soils, but does not tolerate waterlogged conditions.
- Temperature: Hardy in USDA zones 5-8. It can tolerate cold winters, making it suitable for a variety of temperate climates.
- Humidity: Tolerates average humidity levels. Ensure good air circulation around the plant to prevent fungal diseases, especially in humid conditions.
- Fertilizer: Apply a balanced, slow-release fertilizer in early spring to promote healthy growth and flowering. Avoid excessive fertilizer, as it can encourage weak, leggy growth.
- Pruning: Prune lightly to maintain a compact, attractive shape, especially after flowering. Trim back any dead or damaged growth and to encourage denser foliage.
- Propagation: Easily propagated by softwood or semi-hardwood cuttings taken in late spring or early summer. Rooting hormone can help promote faster rooting.
- Pests/Diseases: Generally resistant to pests but can occasionally attract aphids or scale insects. Watch for fungal diseases such as powdery mildew, particularly in damp conditions.
- Landscape Use: Ideal for ground cover, cascading over walls, or planted along slopes for erosion control. Its low-growing, spreading nature and variegated foliage make it perfect for adding texture and color to rockeries, containers, and borders. It is also an excellent choice for attracting wildlife with its berries.
