American hazelnut

American hazelnut (Corylus americana) is a North American species of hazelnut native to eastern North America, including eastern Canada, the eastern United States and Mexico.The American Filbert is a multi-stemmed shrub with a rounded top and an open, often wide-spreading base. Because of its size, it is adapts well to naturalizing and other nonformal areas. It bears annual, abundant crops of small, sweet tasting nuts. It will bear in 2-3 years after planting. The nuts are easy to crack and drop free of the husk when mature. (Plant multiple trees with the same flowering time to ensure pollination) (zone 4-9)


Notes: American hazelnut is a small tree with an edible nut. It is a medium to fast growing species, that suckers moderately, eventually producing a multi-stemmed, clump appearance. American Hazelnut grows as a strong multi-stemmed shrub, with their edible nuts maturing in September-October. It is planted by wildlife enthusiasts to attract and keep game in an area. The nuts produced by American hazelnut are a mast of squirrels, deer, turkey, woodpeckers, pheasants and other animals. The male catkins are a food staple of ruffed grouse throughout the winter.When the male nut is developed, the female nut or Calyx is developed to perfection. The Berry is edible to humans, though its flavor is considered.

American Hazelnut is a unisexual species, with separate male and female parts on the same branch. A single tree can produce nuts, but a small colony of trees may be needed for high yields. Cross-pollination is achieved by wind. European hazelnut, on the other hand, is self-incompatible, requiring a second plant for nut production. American hazelnut can sometimes become overly competitive in disturbed ecosystems such as native prairie that is not allowed to burn due to instituted fire control causing conditions unfavorable for native prairie species. While the top of plant is susceptible to fire, the rhizomes are able to withstand moderate and infrequent fires. Conifer regeneration can also be hindered by the plant’s aggressive growth.
