Red Oak
Family: Fagaceae (View Members of Fagaceae)

Genus and species: Quercus rubra

Leaves: The leaves are 4-9" (10-23cm) long and 3-6" (7.5-15cm) wide. (View Measured Leaf) Since they fall under the lobed leaves category, they contain lobes that are each bristle-tipped at the end. However, the lobes are almost wavy and are much shallower than the Pin Oak and even the Black and Scarlet Oaks. The leaves are dull green on top, paler beneath with tufts of hair in angles along the midvein.(View Leaves)

Bark: The bark is relatively dark gray or blackish in color. It is rough and has scaly ridges. If part of the bark is broken off in an area, it may reveal the bark underneath which has a reddish tint to it. (View Bark) The buds on the Red Oak are hairless, in comparison to the Black Oak, which has hairy buds.

Fruit: Since this is an oak, it has acorns as the fruit of the tree. They are larger than those of the Black Oak and are 0.75- 1.25" (2-3cm) in length. They have a pointed tip at the bottom (opposite the cap). The cap is broad and covers about 1/3 of the fruit. It is blunt, tightly overlapping and reddish in color.(View Fruit)

Tree: The tree has a rounded crown of spreading branches and can grow to 60-90' (18-27m) in height, as pictured to the left.

Range and Habitat: These trees can be found from Ontario to Maine, south to Georgia, west to Oklahoma and north to Minnesota. They are most commonly found in sandy and rocky soils.
