Quercus biolor


The swamp white oak is somewhat scattered across its range, not always growing in abundance. It may be confused with white oak or swamp chestnut oak at a glance, and is a good producer of acorns.


Eastern US and Canada south to Alabama; distribution spotty in southern portion of its range.

Distribution Map

4" to 10" long, wider near the apex, with rounded lobes and shallow sinuses. Sinuses may vary in depth giving the leaf an irregular margin. Top of leaf is shiny green while the underside is silvery green or almost white.

Look-alike oaks:

Swamp Chestnut Oak - leaves of swamp chestnut oak have more of a sawtooth margin with more "teeth" or lobes than those of swamp white oak. Acorns of swamp chestnut are also much larger.

White oak - bark and leaves may be similar at a glance, but leaves of white oak have deep sinuses while those of swamp white oak are very shallow. White oak also favors uplands while swamp white oak favors bottomlands.

Chinkapin Oak - Bark may be similar, but that of swamp white oak is usually more scaly. Leaves of chinkapin oak have a sawtooth margin with more "teeth" than the lobes of swamp white oak. Also, chinkapin oak is found in upland limestone soils while swamp white oak is found in bottomlands.
