Additional Information
The American Hazelnut is a medium to fast growing shrub and an Indiana native. Being monoecious, the male catkins are 1 1/2 to 3" long, that emerge yellowish brown and are quite showy in early spring. The female catkins are inconspicuous with its stigma and style barely protruding out of the buds, but the color is a rich red. The American Hazelnut is a great large shrub for native restoration projects or adding seasonal interest and texture to the landscape. With that being said, Corylus americana needs to be pruned if in a formal landscape setting. Some pests and diseases that effect the American Hazelnut are blight, crown gall, leaf spot diseases, Japanese leafhoppers, scale insects and caterpillars. With proper horticultural practices, these issues are minimal.
