Plant Details

Although lberts and hazelnuts are usually thought of as trees grown for their edible nuts, most listed here are grown for their pleasing ornamental value. Plants have separate female and male owers; female blossoms are inconspicuous, while male ones, appearing in pendent catkins on bare branches in winter or early spring, are showy. Leaves are roundish to oval, with toothed margins.

C. avellana. EUROPEAN FILBERT. Shrub. European native grows to 1015 ft. high and wide. Ornamental selections are more widely grown than the species; the following two are popular.

'Contorta'. HARRY LAUDER'S WALKING STICK. Rounded growth to 810 ft. tall, 12 ft. wide. Grown for fantastically gnarled and twisted branches and twigs, revealed after its 2- to 2-in. leaves turn yellow and drop in autumn. Branches are used in ower arrangements. Plants are almost always grafted, so suckers arising from the base below the graft should be removed; they won't have contorted form.

'Fuscorubra' ('Atropurpurea'). Grows to 1015 ft. high and wide, with 3- to 4-in., reddish purple leaves.

C. maxima. GIANT FILBERT. Shrub or tree. Native to southeastern Europe. One of the species grown for nuts. Suckering shrub to 1215 ft. high and wide; can be trained as small tree. 'Purpurea', most widely grown ornamental form, has rich dark purple leaves to 6 in. long; male catkins are also heavily tinted purple. In most areas, leaves fade to green by early summer.
