Scarlet Oak is scientifically classified as Quercus coccinea. This tree is well-known for its vibrant fall foliage, which typically changes to a brilliant scarlet red, hence its common name. Quercus coccinea is a medium to large deciduous tree that is part of the beech family, and it is native to eastern North America. It thrives in a variety of soil conditions but prefers well-drained sandy or loamy soils. The leaves are lobed and can grow quite large, adding aesthetic value during the growing season.

In contrast, the other options refer to different species that do not possess the characteristics associated with Scarlet Oak. Oxydendrum arboreum, commonly known as the sourwood tree, is known for its white, bell-shaped flowers and is valued for its ornamental qualities. Pyrus calleryana, or the Callery pear, is notable for its spring blooms and has become popular in urban landscapes but is not directly related to oaks. Lastly, Populus tremuloides, known as quaking aspen, is recognized for its distinctive trembling leaves and its ability to form extensive clonal groves, entirely differing in appearance and ecological role from Quercus coccinea.
