Corylus- Hazel, Filbert

In cold climates hazels often produce very few nuts, since the early flowers are killed by night frost. However, there are a number of ornamental forms for use in the garden.

Situation:

The corkscrew hazel and the brown hazel make fine specimen trees for small gardens.

Soil:

Standard or slightly calcereous garden soil. Propagation Species are grown from seed, cultivars by layering or by grafting on Corylus colurna stock.

Corylus avellana, common hazel: Ornamental forms are ‘Contorta’, the corkscrew hazel, which has twisted branches; and ‘Pendula’, a beautiful weeping form. ‘Red Zellernut’ is grown for its nuts; it has red foliage. Corylus maxima, filbert: Because of its deep-red, almost black foliage, the cultivar ‘Atropurpurea’ is particularly popular; it provides a handsome contrast to other shrubs. Height to 5 m, usually grown as a shrub, sometimes as a small tree. The catkins, too, are purple red.
