Hickory, alder and cherry are all wood that will work in a rustic kitchen, but none represent the charm of rustic design more than pine. Heart of pine flooring, which is made from the heartwood of the tree, can range in color from dark brown to deep orange. Pine is also a great choice for the cabinetry, butcher block countertops and kitchen islands. When it comes to rustic charm, the knots in the pine are a plus, so when seeking out your materials, the knottier the better. In fact, just ask the manufacturer for knotty pine.
