Sweet gum ("Liquidambar styraciflua") and red maple are the most abundant trees in the hardwood swamp forests. American holly ("Ilex opaca"), a broadleaf evergreen tree, is common. Pin oak ("Quercus palustris"), swamp white oak ("Quercus bicolor"), willow oak ("Quercus phellos"), tulip tree ("Liriodendron tulipifera"), sour gum, and sweet bay magnolia are associates.
