Cornus alba Sibirica is a stunning deciduous shrub known for its vibrant red stems and attractive foliage. This dogwood variety is highly prized for its striking winter colour and year-round interest.
Cornus alba Sibirica is an excellent choice for adding colour and texture to your garden. Its bright red stems are particularly eye-catching in the winter months when the leaves have fallen, making it ideal for winter gardens, mixed borders, and as a striking focal point. The green leaves turn an attractive red-purple in autumn, adding to its seasonal appeal.
This dogwood thrives in full sun to partial shade and prefers well-drained, moist soil. It is a hardy plant, tolerant of various soil types, including clay. Regular pruning is recommended to encourage new growth, which produces the most vibrant stem colour. Space plants about 1.5-2 metres apart to accommodate its mature size, typically reaching 2-3 metres in height and width.
In the garden, Cornus alba Sibirica is best planted where its colourful stems can be appreciated, such as along pathways or against a backdrop of evergreen shrubs. It is also suitable for wildlife gardens, providing food and shelter for birds. The small white flowers in late spring, followed by clusters of white berries, add to its ornamental value.
Field-grown plants are grown directly in open fields, enabling their roots to spread and develop naturally, resulting in larger size, established root systems, and increased resilience. When transporting these plants, hessian, a coarse fabric made from natural fibres like jute, is commonly used to wrap their roots, providing protection during transportation and handling.
Trimming: Prune in late winter or early spring to encourage vibrant stem colour and maintain a desirable shape. Remove up to one-third of the oldest stems at ground level to promote new growth.
Fertilising: Apply a balanced, slow-release fertiliser in early spring to support healthy growth. Avoid high-nitrogen fertilisers to prevent excessive leafy growth.
Watering: Water regularly during the establishment phase and during dry spells. Cornus Alba prefers consistently moist soil but ensure good drainage to prevent waterlogging.
Pest Control: Monitor for common pests such as aphids and scale insects. Treat infestations with insecticidal soap or horticultural oil.
Disease Management: Watch for signs of canker and leaf spot diseases. Prune out and dispose of infected branches to prevent the spread of disease. Ensure good air circulation and avoid overhead watering to minimise disease risk. Mulch around the base to retain soil moisture and regulate temperature.
