Deciduous, from eastern and central USA.
Scarlet oaks are often mistaken for pin oaks.
But the big difference are the very bright red leaves of scarlet oaks in autumn. Pin oak leaves are more bronze-coloured.
Scarlet oaks are taller, narrower (more cylindrical in shape) with a less spreading canopy than most oaks. The outward branches tend to droop at their ends.
After soaking to remove tannins and toxins, the acorns can be ground to make a flour or roasted as a coffee substitute.
