Description
Corylus avellana 'Roter Zeller' 50 cm C5 | Red-leaved hazel
The red-leaved hazel support-bracket form brings the recognised character of Corylus avellana 'Roter Zeller' to the garden in a clearly presented ornamental form. Known as Red-leaved hazel, and also as purple-leaved hazel, it is a deciduous shrub with upright, bushy and spreading growth. The support-bracket form gives the plant a defined structural presence, while its natural habit adds breadth and fullness around this presentation. It can reach an average mature height of approximately 5 metres and may become broad, so allow enough space for its overall shape. Its broad leaves are dark red to purple, giving the shrub strong colour from spring through the growing season. Yellow and red catkins appear early, adding seasonal interest in February and March. Unlike an evergreen shrub, this hazel loses its leaves in autumn. It is a hardy plant, although its broad habit means that space and positioning should be considered carefully. In suitable conditions, it can also produce hazelnuts, but the crop depends on pollination. As a member of Corylus, this cultivar combines the familiar structure of hazel with a darker ornamental leaf colour and the specific visual presentation of the support-bracket form.
Key features of red-leaved hazel (Corylus avellana 'Roter Zeller') in support-bracket form
- Early seasonal interest: Yellow and red catkins or flowers appear in February and March. They are a notable feature at a time when many garden plants have little floral display. The early catkins add detail to the structured outline of the support-bracket form.
- Decorative foliage: The deciduous leaves range from red to dark red and purple. This colour gives the shrub a strong ornamental role and creates contrast with plants that have greener foliage. The broad leaves also add visual fullness to its upright, bushy and spreading habit.
- Aspect and soil: Choose a position in full sun or partial shade. The soil should be nutrient-rich and humus-rich, with good drainage and light moisture. It should retain some moisture without becoming waterlogged, which is especially important in the wet conditions found in many UK gardens.
- Vigorous garden presence: This is a vigorous shrub that can become broad as it develops. The support-bracket form gives it a defined visual presentation, while the plant’s spreading habit contributes to a substantial overall silhouette. In an exposed UK garden, consider a sheltered position rather than making a specific wind-resistance assumption.
- Garden category: This plant suits the broad range of hardy shrubs for gardens where foliage, early catkins and a firm structural presence are important. Its hardiness and adaptable aspect make it relevant to a range of UK garden settings.
Uses of the red-leaved hazel support-bracket form in the garden
- Defined feature: The support-bracket form works well as a solitary feature where its dark red to purple foliage and early catkins can be seen clearly. Its presented structure adds visual definition without removing the broad, bushy character of the shrub.
- Group planting and hedging: This form can also be used in group planting or as part of a hedge. The spreading habit helps create a fuller impression, while the dark foliage brings contrast to a mixed planting. Allow for its potential breadth when choosing its position.
- Woodland-edge settings: The plant is suitable for a woodland-edge setting, particularly where full sun or partial shade is available. It can be combined with other shrubs, woodland-edge plants, hedging plants and hardy perennials that prefer fertile, well-drained and slightly moist soil.
- Hardiness: Red-leaved hazel is hardy to approximately -29°C to -12°C and is generally placed in USDA zones 4 to 8. This is a general range, not a guarantee for every UK microclimate. Aspect, drainage and shelter still matter, especially in exposed or very wet gardens.
- Ornamental value: The main appeal comes from the dark foliage, the early yellow and red catkins and the defined visual presence of the support-bracket form. Together, these features give the shrub interest across more than one season.
The support-bracket form is suited to gardeners seeking a hardy red-leaved hazel with a defined ornamental presence, whether used as a solitary feature, in a group, as part of a hedge or at the edge of a UK woodland-style planting.
