Corylus cornuta

Corylus cornuta, commonly known as beaked hazelnut or beaked filbert, is a species of deciduous shrub in the birch family Betulaceae. It is native to North America, where it is found in Canada and the United States. The plant is notable for its unique fruit, which is encased in a long, tubular involucre that resembles a beak, hence the name "beaked hazelnut".

Description

Corylus cornuta is a large shrub that can grow up to 2-4 meters in height. It has rounded leaves with double-serrated edges and a pointed tip. The leaves are dark green on the upper surface and paler below. The shrub produces male and female flowers on the same plant (monoecious). The male flowers are yellowish-brown catkins that appear in early spring, while the female flowers are small and largely hidden in the buds, with only the bright red styles visible.

The fruit of Corylus cornuta is a nut, which is surrounded by a hard shell and enclosed in a unique, elongated involucre that extends well beyond the nut, forming a structure that resembles a beak. The nuts are edible and are a source of food for various wildlife species, as well as being harvested by humans for consumption.

Habitat and Distribution

Corylus cornuta is widely distributed across Canada and the northern United States. It prefers moist, well-drained soils and is commonly found in woodlands, forest edges, and open fields. The plant is tolerant of a range of light conditions, from full sun to partial shade.

Ecological Role

The beaked hazelnut plays a significant role in its ecosystem. It provides food for a variety of animals, including squirrels, deer, and birds, which rely on the nuts as a source of nutrition. Additionally, the shrub offers shelter and nesting sites for various species. Its presence in the understory of forests and woodlands contributes to biodiversity and habitat complexity.
