Excerpt from The Morton Arboretum: https://mortonarb.org/plant-and-protect/trees-and-plants/northern-red-oak/
 
Northern red oak is a Midwest native and is one of the faster growing oaks for the home landscape. The leaves are handsome throughout the year, emerging pinkish-red, turning lustrous dark green in summer, and changing to russet-red to bright red in autumn. Its tolerance of salt and air pollution makes it a good tree for more exposed areas.
