Hazel 'Webb's Prize Cob'


Description Corylus avellana 'Webb's Prize Cob' Shrub | Hazel 'Webb's Prize Cob'

Hazel 'Webb's Prize Cob' shrub is the shrub form of Corylus avellana 'Webb's Prize Cob', also known as Hazel 'Webb's Prize Cob'. It has an upright, bushy habit that creates a broad and natural garden silhouette. Green foliage gives the plant a fresh summer appearance, while yellow and brown catkins add seasonal interest early in the year. This is a deciduous shrub, so it loses its leaves for winter and returns to leaf in spring. At maturity, it reaches approximately 4 metres in height, making it a useful choice where a substantial shrub is wanted in a larger border or garden setting. The full, branching presence works well for specimen planting, group planting and informal hedges. It also suits wildlife-friendly planting, where its seasonal structure and catkins add interest. As a cultivar of Corylus, it brings the familiar character of Hazel to the garden in a clearly shrub-focused form. The plant also produces edible hazelnuts as a natural plant characteristic, without this being the main reason to grow it. For UK gardens, this hardy shrub offers a strong combination of foliage, winter structure, early flowers and practical garden value.

Key features of Hazel 'Webb's Prize Cob' (Corylus avellana 'Webb's Prize Cob')

  • Early seasonal flowering: This early-flowering shrub is notable for its catkins from January to March. The flowers or catkins are yellow and brown, bringing colour and interest to the garden before the main summer display begins.
  • Deciduous green foliage: The shrub carries green deciduous foliage during the growing season. Its leaves provide a natural green backdrop for the catkins and help give the plant a full, garden-friendly presence.
  • Aspect and soil: Plant this Hazel shrub in full sun or partial shade. It prefers fertile, humus-rich, well-drained and slightly moist soil. In the often wet conditions of UK gardens, avoid poorly drained ground and keep the root zone light and free from waterlogging.
  • Upright, bushy growth: The shrub develops an upright, bushy habit and can reach approximately 4 metres when mature. Its branching begins from a low, garden-oriented framework, creating a fuller and more natural presence than a single-trunk trained form.
  • Wildlife value: Hazel 'Webb's Prize Cob' provides value for birds and other wildlife. This makes it a useful choice for a wildlife garden as well as for informal planting with a natural character.

Uses of the Hazel 'Webb's Prize Cob' shrub in the garden

  • Specimen planting: Use this Hazel shrub as a specimen where its upright, bushy silhouette can be seen clearly. Its fuller form gives structure to a larger border and keeps interest through early catkins and green summer foliage.
  • Groups and informal hedges: Several shrubs can be used in group planting or as an informal hedge. The natural branching habit gives the planting a relaxed landscape style and can provide structure and screening without the formal look of a tightly trained plant.
  • Hardiness: This shrub has a hardiness range of approximately -23.3°C to -17.8°C and is rated as USDA zone 6. It is therefore suited to many UK gardens, including areas where winter conditions can be severe.
  • Plant combinations: Combine it with compatible deciduous shrubs, woodland-style planting and herbaceous plants that tolerate full sun or partial shade. Suitable partners should also favour fertile, well-drained soil, so the planting remains consistent in its growing needs.
  • Garden value: The main ornamental appeal comes from the full upright-bushy shape, green foliage and early yellow-brown catkins. Its value for birds and other wildlife adds another reason to include it in a natural garden scheme.

This shrub form is a practical choice for larger borders, informal hedge planting, group planting and landscape-style gardens. It suits gardeners looking for a hardy shrub with a full presence, early seasonal interest and wildlife value. It combines well with other hardy shrubs and suitable herbaceous planting in UK gardens where the soil is fertile, slightly moist and well drained. Hazel 'Webb's Prize Cob' shrub brings together natural structure, green summer foliage and early catkins for suitable wildlife-friendly planting schemes.

Planting & care Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

We would like to provide some tips on how to plant and care for a Corylus avellana 'Webb's Prize Cob' Shrub. By following these tips, you can be sure to enjoy your Hazel 'Webb's Prize Cob' for a long time.

Ideal placement of a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

Choose a sunny or lightly shaded position with plenty of room for the shrub to spread. It grows best in fertile, humus-rich, well-drained soil that retains some moisture but does not remain waterlogged. A sheltered position is helpful, although established plants tolerate normal British garden conditions well.

How do I plant a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')?

Plant bare-root plants from late autumn to late winter, provided the soil is not frozen or waterlogged, and container-grown plants at other times when the soil can be worked. Improve poor soil with well-rotted organic matter, plant at the same depth as in the pot or nursery bed, and firm the soil gently around the roots. Water thoroughly after planting and keep the root zone moist during the first growing season; allow ample space for the mature shrub.

Pruning a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

Pruning is usually carried out in late winter while the plant is dormant, or after harvesting if only light maintenance is needed. Remove dead, damaged, crossing and weak stems, together with unwanted suckers arising from the base. Thin out some of the oldest wood periodically to encourage vigorous new growth, but avoid excessive cutting if you want a good nut crop.

Watering a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

Water thoroughly after planting and during prolonged dry spells in the first few years. Established shrubs are generally resilient, but they crop and grow better when the soil does not dry out for long during spring and summer. Plants grown in containers need more regular watering, while consistently saturated soil can damage the roots.

Fertilising a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

Apply a balanced general-purpose fertiliser in early spring, following the product instructions. A mulch of well-rotted compost or manure around the root zone can improve soil structure and provide a steady supply of nutrients. Avoid excessive nitrogen, as this can encourage leafy growth at the expense of flowering and nut production.

The characteristics of a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

This deciduous hazel is grown for its catkins and edible cobnuts, which generally ripen in early autumn when pollination has been successful. 'Webb's Prize Cob' is a traditional heavy-cropping cultivar, but it benefits from another compatible hazel nearby because hazels are not reliably self-fertile. It also provides useful habitat and food for wildlife, although nuts may be taken by squirrels and birds before they are harvested.

Separating/dividing a Corylus avellana 'Webb's Prize Cob' Shrub (Hazel 'Webb's Prize Cob')

Corylus avellana 'Webb's Prize Cob' is a woody shrub and is not normally divided or split. Propagation is more commonly carried out by layering, taking suitable cuttings, or grafting in specialist production. For garden maintenance, remove unwanted suckers rather than attempting to divide the established root system.

The young stems have smooth, grey-brown bark, while older branches become darker and more textured. The bark is mainly of structural interest rather than a major ornamental feature.

Is Corylus avellana 'Webb's Prize Cob' Shrub poisonous?

Warning: This plant may contain toxic substances. Ingestion of any part of the plant or contact with its sap may pose health risks, particularly to children and pets such as cats and dogs. We recommend keeping the plant out of reach of children and animals and wearing protective gloves when carrying out maintenance work, such as pruning or transplanting. If poisoning is suspected, seek immediate medical or veterinary advice. This information is provided as a general safety notice.

It can be grown temporarily in a large container, but it is not ideal for long-term pot cultivation because it becomes a substantial, spreading shrub. Use a sturdy pot with drainage, water regularly, feed during the growing season and protect the container from severe winter cold; planting in the ground is usually preferable.
