Wood Species Guide
Swamp White Oak
Quercus bicolor
Also called: Bicolor Oak, Swamp Oak, White Oak (in the lumber trade)
What Swamp White Oak looks like
Light to medium tan brown heartwood, often a touch darker than white oak, with a pale sapwood band.
Grain and texture
Coarse, open grain, usually straight. Quartersawn boards show strong ray fleck.
Working Swamp White Oak: planing, cutting and gluing
One of the hardest and heaviest white oaks, so it dulls blades a bit faster. It machines cleanly with sharp tooling, glues well and steam bends nicely. Pre-drill for screws.
Finishing Swamp White Oak: oil, film finishes and epoxy
Stains evenly and looks great with oil, hardwax oil or a clear film finish. Put a seal coat down before any epoxy, since the open grain still outgasses. Avoid iron contact with the bare wood.
Durability, stability and Florida humidity
The heartwood resists decay very well and is used for boat parts and barrels like other white oaks. Movement is moderate to large. In Florida, acclimate it well before final milling and finish both faces.
Shop notes from our Fort Myers shop
Swamp white oak is a popular street and park tree, so urban salvage slabs are out there, and they are heavy, hard and handsome. It is a great pick for a dining table that needs to take a beating. Plan on slow drying for thick slabs. We don't stock it, but ask us and we can often source it.
Common uses for Swamp White Oak
Furniture, flooring, cabinets, boatbuilding, barrels, timber framing and live-edge tables.
Sustainability and CITES status
Not listed in the CITES Appendices. Common in its range and widely planted in cities.
Safety and toxicity
- Skin irritation
- Eye irritation
- Respiratory / asthma
- Sensitizer (allergy builds with exposure)
Oak dust often irritates eyes, skin and airways, and some people become allergic with repeated exposure. Long, heavy exposure to fine oak dust is linked to nasal cancer.
