Finding and identifying the American Hazelnut

The American Hazelnut can be found in hardiness zones 4-9, which basically covers the entire United States. It prefers full sun to partial shade, meaning it needs at least four hours of direct sunlight each day. Additionally, it grows in a wide variety of soils, including acidic, alkaline, loamy, moist, rich, sandy, well-drained and clay soils and it is drought-tolerant.

The American Hazelnut can be found at the edges of woodlands, planted in parks and gardens and just about everywhere in between. The key to finding it is being able to identify its unique characteristics.

  • Size. A mature shrub grows to about 15-20 feet tall with a spread of 10-12 feet.
  • Appearance. The hazelnut grows in a rounded shape with a multi-stemmed form and a wide-spreading base.
  • Leaves. Hazelnut leaves are slightly hairy and alternate with heart-shaped sides.
  • Flowers. The hazelnut has distinct flowers, growing both male and female flowers on the same shrub. yellowish-brown male catkins adorn the shrub in the late fall and scaly, green female flowers bloom on it in the spring.
  • Nuts. Smooth brown nuts (also called filberts) form in the sticky green and pokey bracts of the flowers, ripening in fall.

Harvesting hazelnuts

The main challenge of harvesting hazelnuts is beating the local wildlife to them. They are a preferred food source of squirrels, deer, turkey, woodpeckers, pheasants, grouse, quail and bluejays. Additionally, the catkins are a food staple of the roughed grouse during the winter.
