Hazelnut, American

American Hazelnut (Corylus americana)

American Hazelnut is a versatile native shrub that produces delicious sweet nuts while providing exceptional habitat for wildlife and outstanding ecological value. Naturally occurring along woodland edges, open forests, and prairies throughout eastern and central North America, this adaptable shrub forms dense thickets that stabilize soil, create nesting habitat, and produce nutritious nuts enjoyed by both people and wildlife. It is an outstanding addition to food forests, hedgerows, silvopasture systems, and regenerative farms where productivity and biodiversity go hand in hand.

Key Characteristics

Nut production for people and wildlife
American Hazelnut produces clusters of flavorful, sweet nuts enclosed in fringed husks that ripen in late summer to early fall. The nuts are rich in healthy fats, protein, vitamin E, and minerals, making them excellent for fresh eating, baking, roasting, nut butters, and wildlife forage. Squirrels, Eastern Chipmunks, Blue Jays, Wild Turkeys, Northern Bobwhite, Ruffed Grouse, and White-tailed Deer eagerly consume the nutritious crop.

An ecological cornerstone for native wildlife
Beyond its nut production, American Hazelnut is one of the most valuable native shrubs for supporting biodiversity. It serves as a larval host plant for the Polyphemus Moth (Antheraea polyphemus), Imperial Moth (Eacles imperialis), and several other native moth species whose caterpillars provide an essential food source for nesting songbirds. Dense multi-stemmed growth creates excellent nesting cover and winter shelter for birds and small mammals.

A resilient shrub for food forests and regenerative systems
American Hazelnut naturally forms colonies by sending up root suckers, making it ideal for hedgerows, windbreaks, woodland edges, and the shrub layer of food forests. Its extensive root system helps stabilize slopes and reduce erosion while providing long-term structure within permaculture designs and silvopasture systems. It pairs exceptionally well with oak, hickory, persimmon, serviceberry, elderberry, and native wildflowers to create diverse, productive landscapes.

Cold hardy, adaptable, and easy to grow
This hardy native tolerates a wide range of soil types, from loams to heavier clays, provided drainage is adequate. It performs best in full sun to partial shade, with increased sunlight leading to heavier nut production. Planting two or more genetically distinct shrubs improves cross-pollination and results in larger, more consistent harvests.

American Hazelnut thrives with minimal maintenance once established and responds well to occasional renewal pruning to encourage vigorous new growth and maintain productivity. Plant multiple shrubs for improved pollination and nut set, and allow space for natural colony formation if using it in hedgerows or restoration projects. Whether incorporated into a food forest, wildlife planting, silvopasture, or edible landscape, American Hazelnut provides decades of harvests while supporting an extraordinary diversity of native wildlife.
