Family: Fagaceae
Common names: Black oak, Cucharillo, Encino, Encino negro, Mamecillo, Oak, Red oak, Roble, Roble amarillo, Roble colorado, Roble encino, Roblecito, Scarlet oak, Spanish oak
Distributed in: Canada, United States (Mediterranean Sea Region, North America)
Distribution overview: The growth range of Scarlet oak in North America includes Ontario, Alabama, Connecticut, Delaware, Georgia, Indiana, Kentucky, Massachusetts, Maryland, Maine, Michigan, Missouri, Mississippi, North Carolina, Great Smoky Mountain National Park, Arkansas, Illinois, Nebraska, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Vermont, Wisconsin, and West Virginia. The tree can tolerate various soil types, especially poor and sandy soils. It grows with other oaks and in mixed forests on upland ridges and slopes. Scarlet oak is also planted in Great Britain as an ornamental because of its scarlet foliage in the fall season.
Common uses: Baskets, Bent Parts, Boat building, Building materials, Cabinetmaking, Canoes, Chairs, Chests, Concealed parts (Furniture), Cooperages, Core Stock, Decorative veneer, Desks, Dining-room furniture, Domestic flooring, Dowell pins, Dowells, Drawer sides, Excelsior, Figured veneer, Fine furniture, Floor lamps, Flooring, Food containers, Framing, Fuelwood, Furniture , Furniture components, Furniture squares or stock, Hatracks, Interior construction, Interior trim, Joinery, Kitchen cabinets, Lifeboats, Millwork, Pallets, Paneling , Tables , Veneer, Woodenware
Product sources: Although the primary sources of commercial American red oak are northern red oak (Q. rubra) and southern red oak (Q. falcata), various species in the red oak class are mixed and marketed together without distinction. Supplies of red oak are plentiful, and the species is one of the most commonly available domestic hardwoods. Oak in general, and particularly red oak, is the most popular timber for furniture, followed by cherry, pine, mahogany, ash, pecan, hard maple, and walnut.Red oak is also a popular export to other countries, and is one of the most popular American oaks used in Europe.

Oaks are classified into two main groups: red oaks and white oaks. Although members within each group may be similar, they do not have the same characteristics and may differ significantly. The Red oak group is plentiful in eastern Canada and the United States. The name Red oak is used in reference to several similar oaks which include American red oak or Northern red oak (Q. rubra ); Southern red oak, Spanish oak, Swamp red oak, or Cherrybark oak (Q. falcata ); Shumard oak or Pin oak (Q. palustris ); Nuttal oak (Q. nuttallii ); Scarlet oak (Q. coccinea ); and sometimes Black oak (Q. velutina ). Red oaks are often described as beautiful because of grain pattern and character. They tend to be plainer in appearance than white oaks because of their smaller rays, and they are not as watertight as white oaks because of their open pores. The two groups are comparable in strength, and they are both used in steam bending applications.
Red oaks tend to be less resistant to decay than white oaks or European oaks. Also, red oak acorns are much more bitter in taste than white oak acorns.
