Corylus americana x avellana with hulls (Hybrid Hazelnut, American European Filbert) is a hybrid resulting from the crossbreeding of American Hazelnut (Corylus americana) with European Filbert (Corylus avellana).
This hybrid, often known as a hazelnut cultivar or hybrid hazelnut, combines characteristics of both parent species. It may exhibit traits such as adaptability, nut size, and disease resistance, making it a potentially desirable option for cultivation. Specific cultivars within this hybrid category may have unique features, and they are often developed with the aim of improving nut production and other desirable attributes.
The Hybrid Hazelnut results from crossing American Hazelnut with European Filbert, making it an excellent shrub for landscaping and creating habitats for wildlife and birds. Similar to other hazelnuts, it blooms from March to May before the leaves emerge, and it produces large hazelnuts from July to September.
