Also called: Basket Oak, Cow Oak, Michaux Oak, Swamp White Oak (regional, but see note), White Oak (in the lumber trade)
About the name “Swamp Chestnut Oak”
Swamp chestnut oak is a white oak of Southern river bottoms. It is not a chestnut, and it is a different tree from chestnut oak (Quercus montana) of the Appalachian ridges and from swamp white oak (Quercus bicolor) of the North, although some Southern loggers use those names loosely.
What Swamp Chestnut Oak looks like
Light to medium brown heartwood with a pale tan sapwood, much like commercial white oak.
Grain and texture
Coarse, open grain that is often long and straight in good bottomland trees. It splits cleanly along the grain.
Working Swamp Chestnut Oak: planing, cutting and gluing
Works easily for its weight with sharp tools and glues well. It splits so cleanly that it was the classic wood for hand-split basket strips, which is where the name basket oak comes from.
Finishing Swamp Chestnut Oak: oil, film finishes and epoxy
Takes stain, oil and film finishes evenly. Seal the surface before epoxy to keep bubbles out of the pour. Like all oaks, keep iron away from bare wood.
Durability, stability and Florida humidity
Published ratings put the heartwood at moderately durable, a step below the best white oaks. It moves a fair amount with humidity. In Florida, acclimate the wood and finish all faces; use it indoors or under cover.
Shop notes from our Fort Myers shop
Swamp chestnut oak grows in river swamps across north Florida and sometimes comes out of land clearing as big, straight logs. The lumber is sold as white oak and is good for tables, cabinets and flooring. We don't stock it, but ask us and we can often source it.

Safety and toxicity
