Description & Overview

Twisted knotty trunks of Contorted Filbert make a unique ornamental statement in the landscape. Commonly referred to as Harry Lauder’s walking stick, this deciduous shrub provides winter interest with its gray gnarly (but in a good way) branch structure and dangling catkins.

Wildlife Value

Although this species cultivars and hybrids are more often produced and grown for consumption (hazelnut) Contorted Filbert does not produce fruit (nuts). For a similar plant with less ornamental interest and more wildlife value, try native American Filbert.

Maintenance Tips

Allow it to grow naturally and take a curvy form shape. Prune out some branches to allow the interesting ones to show off. Because the majority of Contorted Filberts on the market are grafted onto a different rootstock, suckers can be an ongoing issue. Prune out any suckers that arise and do not resembled the twisty stems true to the grafted species.

Pests/Problems

Corylus avellana ‘Contorta’ is known to have good resistance to filbert blight. Rarely occurring diseases include black knot, crown gall, and leaf spot. Scale may also occur. In years when Japanese beetles are bad, they may attack the foliage.

Leaf Lore

This selection was found in a southeastern English community, Frocester in roughly 1863 growing in a hedgerow. Sited by Victorian gardener Canon Ellacombe, it was eventually given the common name Harry Lauder’s walking stick. Harry Lauder at the time a very well-known singer and comedian, acknowledged for becoming the first performer to sell over a million records. Part of his stage performance included a bit where we wore a kilt (he was Scottish) and used a twisted and severely distorted walking stick. Thus, we have, Corylus avellane.

Companion Plants

Sited as a specimen plant, accent with low growing perennials like John Creech Sedum, Dragon’s Blood Sedum, Rozanne Geranium, or creeping evergreens like Blue Chip Juniper and Calgary Carpet Juniper. In part shade choose All Gold Japanese Forest Grass, Herman’s Pride Archangel Lamium, and Canada Wild Ginger.
