California White Oak is found in the valley areas of California. It grows in the fertile valley soil, and is a very large tree. The color tends to be more brown/tan than red oak and is a little harder. The colors and knots have more swirls and blend a little more delicately. The grain is more open and prominent. We offer one grade of White Oak Flooring, Run of the Mill (ROM). ROM is the wood as it comes from the log. It has a rustic natural appearance.
