Scarlet Oak
Quercus coccinea

Description

Quercus coccinea, or scarlet oak, is a durable, low-maintenance tree that thrives in well-drained soils, particularly those that are dry, acidic, and sandy. Scarlet oak is native to eastern and central North America, ranging from southwestern Maine west to Michigan, south to Missouri and Mississippi, and east to South Carolina and the eastern Atlantic coast. It grows best in full sun and is less prone to chlorosis compared to its relative, pin oak (Q. palustris). Pruning in the dormant season helps prevent attracting beetles that could carry oak wilt. It makes an excellent shade tree, especially in drier locations, and can also be used as a street tree, provided it has enough space to reach its mature size. Quercus coccinea drops acorns and a significant number of leaves, with the heaviest shedding in the fall. It is considered moderately messy due to the acorn litter and extensive leaf drop that require regular cleanup.
