Northern red oak is native to the Midwest 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.
This species is native to the Chicago region according to Swink and Wilhelm's Plants of the Chicago Region, with updates made according to current research.
