There are two species of native hazelnuts that you are likely to come upon in the Northeast – Beaked Hazelnut, Corylus cornuta, (see https://naturallycuriouswithmaryholland.wordpress.com/2017/08/14/beaked-hazelnuts-maturing/) and American Hazelnut, Corylus americana. The nuts of both of these species are edible.
The fruit of American Hazelnut is produced in clusters of one to five, with each half-inch brown nut enclosed in a hairy, leaf-like husk with ragged edges. These nuts are maturing now, in September and October. They are best harvested while the husks are still green, as once they turn brown, there will be stiff competition for them from local wildlife.
