Hazelnut Grower of Oregon (HGO) has been in business since 1984, HGO has more than 150 growers who collectively own more than 10,000 acres of prime hazelnut orchards.

Whether you are looking for nutritional information about hazelnuts (also known as filberts), hazelnut recipes, chocolate covered hazelnuts (or other hazelnut delicacies), planning to start your own hazelnut farm or in search of a year-round source for premium Oregon inshell, kernels, or value-added hazelnut products, then you have come to the right place. Ninety-nine percent of all hazelnuts grown in the United States come from the rich soil of the Willamette Valley in Oregon. The region’s gentle climate and abundant rainfall produce larger nuts, with an exquisite flavor and freshness.
