Black Oak
Quercus velutina
Also called: Eastern Black Oak, Yellow Oak, Quercitron, Yellow-bark Oak, Red Oak (in the lumber trade)
About the name “Black Oak”
Eastern black oak (Quercus velutina) is sold as red oak lumber. It is a different tree from California black oak (Quercus kelloggii) of the West Coast.
What Black Oak looks like
Light to medium reddish brown heartwood, often a little browner than northern red oak, with pale sapwood.
Grain and texture
Coarse, very open grain typical of the red oaks, with large pores you can blow air through on end grain.
Working Black Oak: planing, cutting and gluing
Machines, sands and glues well. Black oak trees often have more knots and defects than northern red oak, so the lumber grades lower on average. Sharp cutters keep the large pores from tearing.
Finishing Black Oak: oil, film finishes and epoxy
Takes stain very evenly and is easy to finish. The pores are wide open, so use a grain filler for a glassy finish and always seal coat before an epoxy pour, letting it tack up first.
Durability, stability and Florida humidity
Not decay resistant, and the open pores wick water. Movement is moderate to large. In Florida, keep it indoors, acclimate it, and finish both sides.
Shop notes from our Fort Myers shop
Black oak is one of the common trees behind everyday red oak lumber. When it comes as a slab from a yard or roadside tree, it gives a warm, open-grained top that suits farmhouse and rustic tables. We don't stock it, but ask us and we can often source red oak group lumber.
Common uses for Black Oak
Flooring, furniture, cabinets, millwork, pallets, railroad ties and firewood. The inner bark was once a source of yellow dye.
Sustainability and CITES status
Not listed in the CITES Appendices. Common across the eastern United States and not considered threatened.
Safety and toxicity
- Skin irritation
