Holland Oats

The Known Collection of American Black Walnut comes from Black Walnut trees grown in the Ohio River Valley. This collection of Walnut varies from the bleached light color of Stormy to the rich warm tones of Stills & Nash. It is the perfect complement to our color palettes of the Naturals, Smoked and Reactives collections.

Our American Black Walnut can be selected from two grading options: Rustic grade which celebrates the natural knot presence of Walnut or our Select grade which has a smaller presence of knots and presents as a more unified appearance. Both grades have been culled to minimize the amount of sap.

The Known Collection of American Black Walnut can be specified in two standard platform sizes and can be ordered with a Class A fire treatment for beautiful vertical applications. Custom sizes and finishes are also available.
