While wheat has been Oregon's leading crop since the state was first settled, in recent years nursery and greenhouse products, valued at more than $842 million, have taken over the number-one spot, followed by hay and ryegrass production which bring in $231 million and $138 million respectively. Additionally, more than 170 farm and ranch commodities are commercially produced in the state. Oregon leads the nation in the production of hazelnuts, peppermint oil, blackberries, black raspberries, boysenberries, loganberries, several grass and seed crops, and Christmas trees.
