Description

Quercus coccinea is a medium to large deciduous tree growing to around 5.5–7.3 metres (18–24 feet) with an open, rounded crown; the maximum height is approximately 30 m (100 ft). The trunk diameter at breast height is typically 61 to 91 centimetres (24 to 36 inches) It is a medium-size tree that grows fast and matures relatively early. Seedlings develop a strong taproot with relatively few lateral roots. The leaves are glossy green, 7–17 cm (2+3⁄4–6+3⁄4 in) long and 8–13 cm (3+1⁄4–5 in) broad, with seven lobes, and deep sinuses between the lobes. Each lobe has 3–7 bristle-tipped teeth. The leaf is hairless (unlike the related pin oak (Q. palustris), with tufts of pale orange-brown down where the lobe veins join the central vein). The foliage generally becomes bright scarlet in autumn. The flower color is yellow to green, depending on the season. The acorns are ovate, 7–13 millimetres (1⁄4–1⁄2 inch) broad and 17–31 mm (5⁄8–1+1⁄4 in) long, a third to a half covered in a deep cup, green maturing pale brown about 18 months after pollination; the kernel is very bitter.

Similar species. It can be mistaken for the pin oak, the black oak (Q. velutina), or occasionally the red oak (Q. rubra). On the scarlet oak the sinuses between lobes are C-shaped in comparison to pin oak, which has U-shaped sinuses and the acorns are half covered by a deep cap. …

At the table

Scarlet oak is sometimes planted as an ornamental tree, popular for its bright red fall color. The cultivar 'Splendens' has gained the Royal Horticultural Society's Award of Garden Merit. Scarlet oak has an excellent red color during the fall months and is typically grown for shade and ornamental purposes. The red oak is a popular selection for lumber and is commonly used as a flooring material. Scarlet oak wood has a light to medium color consisting of reds and browns. The scarlet oak has a fairly coarse texture with a relatively large pore size. The durability of scarlet oak is less than the white oak, which has a higher level of decay and rot resistance. Scarlet oak lumber is easy to glue and looks attractive after staining and finishing. It has a distinct, appealing smell common with most oaks. Oak has been classified as a sensitizer, although it does not cause many allergic reactions. Reactions include eye and skin irritations and asthma-like symptoms, but not severe. White oak is typically more expensive than scarlet oak; red oak is in good supply with reasonable pricing, making it a very popular lumber product throughout the USA. Scarlet oak is commonly used in furniture, cabinetry, interior trim, flooring, and veneer. Scarlet oak shares many characteristics with red oak and often falls in the same category as red oak (Quercus rubra) in a broad sense
