Nutty over American Hazelnut!
By Richard Stoll
The American hazelnut (Corylus americana), is a deciduous shrub native to the eastern and central United States including the great state of Indiana. It grows to a height of roughly 8 to 12 feet with a crown spread just as wide. Hazelnut is a medium to large shrub or small tree often multi-stemmed with long outward growing branches that form a dense spreading or spherical shape. It spreads by sending up suckers from underground rhizomes below the surface. It thrives in full sun to part shaded areas.
American hazelnut blooms in early to mid spring produce hanging male catkins about 1 ¼ inches long, and clusters of 2-5 tiny female flowers enclosed in the protective bracts of a bud, with their red styles sticking out at the tip. The male catkins develop in the fall and remain over the winter. The yellowish-brown catkins are showy in the late winter and early spring. Each male flower on a catkin has a pair of bracts and four stamens. Hazelnuts produce edible nuts with ragged papery husks that mature between July and October. Each nut is enclosed in two leaf-like bracts. Fall color varies from bright yellow to deep wine-red.
When used in landscaping, you only need one hazelnut shrub to get nuts. That’s because hazelnuts are monecious (have both male and female flowers on the same plant) and are pollinated by the wind. However, for best nut production, plant multiple hazelnut shrubs together spacing them 5-10 feet apart to be on the safe side.
Here on Stoll Farms, we plant American hazelnut because it was a missing component in our efforts to rewild the land. This native shrub is excellent for wildlife providing food and cover and important for supporting all kinds of animals. The nuts produced by American hazelnut are a mast for whitetail deer, foxes, squirrels, ruffed grouse, bobwhites, turkey, woodpeckers and other animals. The leaves are browsed on by whitetail deer and rabbits and the male catkins are a food staple of ruffed grouse and turkey throughout the winter months. The low-hanging shrubs form a habitat for many animal species.
Hazelnut shrubs grow thick and fast making them excellent as hedgerow, privacy screens, or natural fencing and act as a windbreak to help reduce wind erosion. This thicket forming species provide critical nesting sites for various birds and other wildlife and is a host plant for many butterfly and moth species providing food for their larvae.
So consider adding the American hazelnut to your garden or wildlife habitat restoration project! This native shrub can provide you with delicious hazelnuts or you can leave them for the wildlife to enjoy.
