Hazel - The hazel (Corylus avellana L) is the source of hazelnuts. It forms a shrub up to 20 feet tall, inhabiting open woodlands and scrubs, hedgerows, and the edges of forests. The filbert nut in North American groceries is Corylus maxima, a related species. The European hazelnut is cultivated in North America, primarily as an ornamental. Hazelnuts are in the Birch family (Betulaceae). Curtis Clark |
