Branches that could be used to open a bottle of wine.

Corylus avellana is a deciduous shrub. Often called Harry Lauder's walking stick or corkscrew hazelnut due to its unusual stem growth, it produces catkins in the spring, though no nuts develop as a result. Corkscrew hazelnut is best grown in full sun or partial shade where soil is well-drained yet moist. Thinning plants out periodically can promote the growth of the corkscrewed stems, which are particularly noticeable during the winter when foliage has dropped. It is ideally placed amongst border shrubbery, used as hedging or grown as a focal point.
