Quercus rubra

Northern Red Oaks (quercus rubra) are the grand maestros of native trees in our eco-region supporting close to 500 caterpillar species of moths and butterflies.

Northern red oak is a hardwood and has been extensively planted as an ornamental because of its symmetrical shape and brilliant fall foliage.  It is a deciduous broadleaf tree which can grow to 32m (100 feet) and develops a rounded crown. The bark is smooth and silver-grey when young, and develops warts or ridges with age. Twigs are straight, slender and dark brown. Look out for: the large leaves which have long lobes, each with 1–3 teeth. Its acorns are an important food source.

The tree has leaflets that occur during spring, and it takes place during normal air temperatures. This species does well in cool regions, and it loses flowers during the late spring seasons.

The tree doesn’t have a seed crop, and its leaves emerge during this season. Northern Red Oak tree species has two growing seasons and releases its leaves early in October, where it drops leaves. The best time for leaf drops and leaf outs varies in weeks for Northern Red Oak trees.

Red Oak attracts an even wider array of birds. Jays, crows, turkeys, woodpeckers, ducks, and quail make use of the acorns, while many, many songbirds relish the caterpillars and other small bugs that feed on oak leaves

Trees generally live up to 300 years and prefer well drained soils.
