Corylus avellana 'Contorta' (Alun contorsionat, Alun carliontat)

Corylus avellana 'Contorta', also known as twisted hazel or dwarf twisted hazel, is a decorative variety of the common hazel (Corylus avellana). It is an ornamental plant valued for its unusually twisted and contorted branches, as well as for its early spring flowers.

Size and shape: This hazel variety grows slowly and reaches a height and width of about 2.5-4 meters. The branches are twisted and contorted in an attractive way, giving the plant an interesting sculptural appearance, especially during winter when the leaves have fallen.

Flowers: The plant blooms early in spring, before the leaves appear. The flowers are elongated and yellow-green in color, known as "catkins." The male catkins are longer and more visible, while the female catkins are smaller and less noticeable.

Fruits: Corylus avellana 'Contorta' produces hazelnuts, like the common hazel. The nuts are relatively small, round, and dark brown, protected by a leafy bract. However, fruit production is often limited compared to other Corylus avellana cultivars.

Cultivation: Corylus avellana 'Contorta' grows best in fertile, well-drained soils and in full sun or partial shade. The plant is hardy to low temperatures and adapts to a variety of growing conditions. It withstands temperatures down to -35°C.

Landscape use: Due to its unusual appearance, Corylus avellana 'Contorta' is suitable to be planted as a focal point in gardens or combined with other ornamental plants. It is also suitable for themed gardens, gardens with woody structures, or as a point of interest during winter.
