Hickory is a beautiful American Species. The price range is $4sf to $10sf and is offered by many different manufacturers. You can get it smooth, hand-scraped or wire-bushed (to accentuate the grain). The grain looks a lot like oak. It is naturally a blond floor with brown grain and can have a large color variation because of the brown mineral streaks. There also can be knots in the wood, or they can be selected out and sold at a premium grade.
