Black Oak

Quercus velutina
Fagaceae (oaks)

A mediium-sized tree with a wide-spreading, open crown and tall, straight trunk.

Leaves alternate, simple, with 5–7 bristle-tipped lobes, cut deep or shallow. They are 5–10 inches long, 3–8 inches wide, dark and shiny above, pale and conspicuously fuzzy underneath (the species name, velutina, means "velvety").

Bark is smooth on branches, becoming black and very rough. The inner bark is distinctively mustard yellow or orange, and bitter.

Twigs stout, reddish-brown, hairy at first, smooth with age. End buds sharp-pointed, distinctly angled, covered with gray hairs.

Flowers April–May, in catkins.

Fruits September–October. Acorns soliltary or in pairs, reddish-brown, striped, oval with a rounded tip, 1/2 to 1 inch long. Cup with inner surface and scale edges hairy; deep, covering acorn halfway. Acorns ripen in autumn of second year.

Height: to 85 feet; spread: to 85 feet.
Habitat and conservation: 
Occurs naturally on rocky, sandy or dry upland ridges and slopes; also on sandstone, chert or igneous glades and along borders of woods and fields. Cultivated, it grows on a great variety of sites and will reach commercial saw-log size on almost every soil type, but it is slow-growing and lacks the brilliant autumn coloring that some other oaks have.
Distribution in Missouri: 
Black oak and scarlet oak are both relatively short-lived (less than 120 years). When old-growth shortleaf pine was logged from the Ozarks from 1890 to 1920, scarlet and black oak colonized those lands. Recently these oaks have been declining, and public land managers are working to restore those areas to the original pine woodlands, currently one of our rarest forest communities.
Human connections: 
Black oaks can be used in landscaping and windbreaks, and their wood becomes rough lumber and many wood products, including flooring, pallets, railroad ties and bridge timbers. Historically, Native Americans used oaks to make a wide variety of medicines.
Ecosystem connections: 
A consistent producer of acorns, black oak feeds blue jays, woodpeckers, wild turkey, ruffed grouse, bobwhite, mice, squirrels, raccoons and deer. Many types of animals find homes in its strong branches and in hollow places in the trunks; more inhabit it after the tree falls.
