Quercus coccinea (Scarlet Oak)

One of the most reliably brilliant fall-color trees available, scarlet oak is also confirmed tolerant of black walnut and serves as a documented larval host for six named hairstreak and duskywing butterflies plus the Imperial moth - genuine ecological substance behind its ornamental reputation.

Species Overview

Quercus coccinea, or scarlet oak, is a large deciduous tree native to the central and eastern United States, eventually maturing to 50 to 80 feet with a rounded, open crown. It is best known for its vibrant scarlet red fall foliage, with deeply cut, bristle-tipped leaves that stay glossy green through summer before turning a brilliant, long-lasting red in autumn.

Application

• Ornamental fall-color specimen plantings - among the most reliable scarlet displays
