collage of White Oak and Swamp White Oak

White Oak (Quercus alba) vs. Swamp White Oak (Quercus bicolor)

Updated August 31st, 2020

These two oaks are sometimes confused; young white oaks growing in shade have shallowly-lobed leaves that can be confused with those of swamp white oaks. Although swamp white oaks are naturally found on wetter sites, both species are widely planted and can be found together in landscaping. The species are usually easily distinguished if you know what to look for. They can, however, hybridize and form intergrades; although hybrids are rare, it may not be possible to identify all trees.

White Oak (Quercus alba) vs. Bur Oak (Quercus macrocarpa)

Updated July 24th, 2020

These two oaks of the white oak group are sometimes confused, but are relatively easy to tell apart by leaf, acorns, bark, and shape. Although they can co-occur on some sites, Bur Oak is more likely in flood-prone bottomlands, fire-prone savannas at the transition zone to prairie, on calcareous soils, or on extremely dry ridges, whereas white oak is more likely in mesic to slightly dry oak forests. These species are more likely to occur together in landscaping than in the wild.
