Scarlet Oak (Quercus coccinea) vs. Black Oak (Quercus velutina)
Updated November 20th, 2019Black oak is more variable than scarlet oak. Some trees, especially young trees growing in shade, are easily identifiable as black oak, but others can be difficult to distinguish. Mature trees have similar bark. In identifications it is easier to exclude scarlet oak than black oak; black oaks can have pubescence on twigs and petioles. Acorns look similar but can be distinguished by the presence or absence of rings of pits, and the looseness of cap scales. A close view of the buds can also usually distinguish them.
