35 Types of Oak Trees with Their Bark and Leaves

The genus Quercus and the Fagaceae beech family include hardwood trees known as oak trees. White oak trees and red oak trees are the two types of oak trees found in nature.

The bark, leaves, acorns, and general form of the oak tree can all be used to identify its type. In temperate countries in the Northern Hemisphere, oaks are one of the most frequent tree species in woods and parks.

Oaks are a prized tree in any landscape because of their graceful height and tough wood. This guide will teach you what to look for if you’re trying for the perfect oak tree for your garden landscape or want to identify oaks in the woods.

Oak Tree Facts

There are roughly 450 oaks species in North America, with 58 of them native. The majority of oaks are deciduous, which means that they lose their leaves in the autumn. You’ll also find a few evergreen varieties among the hundreds of oak species.

Oaks are huge trees, as well. The tallest oaks, some exceeding 100 feet (30 meters), may be found among them. The large spread of oak trees is due to their robust branches, which may reach up to 135 (41 m) long.

Acorns (also known as oak nuts) are the fruit of the oak trees. The cupule, or cup, of an acorn is smooth and leathery. Only after 20 to 30 years do many oak trees produce acorns, which they may do up to a thousand each year.

The acorn is the flesh of an oak tree. Because it contains a seed, acorn is technically a fruit. Because of its hard outer shell, acorn is also classified as a type of nut.

Oak Tree Varieties

White oaks (Quercus, subgenus leucobalanus) and red oaks (Quercus, subgenus Erythrobalanus) are the two types of oak trees that exist. Gray-colored bark and leaves with rounded lobes, but no bristles, distinguish white oaks. The bark of red oaks is darker, with pointed lobes and bristles on the leaves.

Red Oak Trees

Lobed leaves with pointed tips and little bristles at the lobed tips are common on red oak trees. They have a very bitter, unpalatable taste and take two years to mature their acorns. The leaves are 5 to 9 inches (12 to 22 cm) long, on average.

White Oak Trees

The lobed leaves of white oak trees are rounded and lack bristles, which is a common feature. They have a sweet or slightly bitter flavor and take one year to mature their acorns. White oaks have the same length of leaves as red oaks.

Oak Tree Bark

Young oak trees have smooth bark that has a silvery brown color. The bark of oak trees becomes fissured as they mature, resulting in deep grooves and ridges. The bark of different oak species changes from light gray (white oak) to extremely dark, almost black (red oak).

Oak Tree Leaves

White oak leaves vs. red oak leaves: white oak leaves usually have rounded tip (left) whereas the leaves of red oak leaves generally have pointed tips (right)

Oak trees are generally recognized by their unique lobed leaves. The tips of white oak leaves are usually rounded, while the tips of red oak leaves are usually pointed. Without bristles at the lobe tip, white oak leaves have rounded lobes and rounded tips.

Rounded serrations may also be seen along the leaf margins. The leaves of red oak trees are typically lobed and tipped with bristles. Species of red oak trees have a wider range of leaf shapes, with some having tooth-like margins and others having smooth margins.

Oak Tree Acorns

Acorns that are white oak develop quicker than those of red oak. White oak acorns take one year to develop, whereas red oak fruit takes about two years to develop.

White oak acorns are smaller and lighter than red oak acorns. The flavor of white oak acorns is sweet or slightly bitter. The bitter, unpalatable taste of acorns from red oak trees.

Oak Tree Identification

Deep fissures and ridges in the bark of oak trees are a good indication that they’re identifying oak trees. Oaks have a whitish-gray to dark, almost black bark color.

Oak trees with deeply lobed leaves with pointed or rounded tips are easily identified. Let’s take a closer look at white oaks and red oaks, two common oak tree types.

Types of Red Oak Trees (With Pictures)

Pin Oak Tree (Quercus palustris)

Pin oak trees reach a height of 72 feet (22 meters) and have leaves that grow to be medium size. Since to lower branches drooping down, the branch growth hides the trunk.

The loose, spreading growth of the pin oak’s upper canopy distinguishes it from other trees. Immature Pin oak trees have smooth red-gray bark that gets rougher and grayer as it ages, with the bark of mature Pin oak trees being rough.

Oak tree leaves: Glossy green leaves with deeply lobed margins and pointed tips distinguish pin oaks. The leaves are hairless and each lobe has bristled teeth.

Water Oak Tree (Quercus nigra)

Water oak trees are up to 100 feet (30 meters) tall and have leaves that don’t fall until mid-winter. The water oak’s distinctive spoon-shaped dull green leaves grow in clusters and are easy to distinguish.

Oak tree bark: As the oak grows, its bark becomes rough and scaly, and it turns black.

Oak tree leaves: The form of water oak leaves varies, from rounded like an oblong spoon to three-lobed with bristle tips.


Black Oak Tree (Quercus velutina)

With dense foliage that grows into a large flat-topped crown, black oak tree bark and leaves grow up to 100 feet (30 meters) tall. Glossy green, highly lobed leaves with U-shaped notches are used to identify black oaks. The inner bark of this species of red oak is orangey, while the exterior is dark gray.

Oak tree bark: The black oak is distinguished by its long shallow fissures and scaly grayish-black bark.

Oak tree leaves: The glossy, deep-green leaves with U-shaped notches and pointed lobes are used to identify black oak. Fine hairs on the underside of leaves are a good sign.

Cherrybark Oak (Quercus pagoda)

Cherrybark oaks may reach heights of between 100 and 130 feet (30 and 40 meters) and have bark and leaves similar to those of a cherry. One of the fastest growing oaks is this kind. The bark of the oak species is similar to that of the black cherry tree, and it got its name from there.

Oak tree bark: The thin ridges of cherrybark oaks’ dark gray scaly bark distinguish it.

Oak tree leaves: The haphazard arrangement of the lobes on either side of the blade is a distinguishing characteristic of cherrybark oak leaves. The underside of the leaves is covered in fine hairs and are glossy, dark green.

Northern Red Oak (Quercus rubra)

Northern red oak trees may grow up to 92 feet (28 meters) tall and are sometimes even taller. The foliage of the red oak tree is lobed, but not as deeply as those of many other red oaks. One of the most popular oak trees in North America is this species of oak tree.

Oak tree bark: The brilliant streaks in the center of fissures ascending up the tree are a distinctive identifying characteristic of red oak bark. Dark brown to reddish-gray bark is used.

Oak tree leaves: The tip of the lobes on northern red oak leaves are serrated, and the leaves are dark green and smooth.


Scarlet Oak (Quercus coccinea)

The scarlet oak tree is a 67 to 100-foot-tall (20 to 30m) medium-sized oak. The pin oak or black oak appear to be similar to the oak tree. The leaf shape, on the other hand, distinguishes between the two species. Lobed leaves with C-shaped notches, not U-shaped ones, are seen on scarlet oaks.

The leaves and bark of the scarlet oak tree

Oak tree bark: Irregular broad scaly ridges and small fissures characterize the scarlet oak bark.

Oak tree leaves: The deep lobes and C-shaped sinuses (notches between the lobes) of scarlet oak leaves are used to identify them.

Southern Red Oak (Quercus falcata)

The southern red oak thrives on sandy soil and full sun in the southern states, where it grows alongside its leaves. Between 82 and 100 feet (25 and 30 meters) tall, the deciduous tree. The acorns, which are orangey-brown and smaller than other oak trees, are a distinguishing feature of the southern red oak.

Oak tree bark: With shallow fissures and rough ridges, laurel oak bark is dark brown.

Oak tree leaves: Diamond-shaped glossy green leaves characterize laurel oak. Long, thin leaves with lobes are occasionally seen. Diamond-leaf oak is the name given to the oak.

Willow Oak Tree (Quercus phellos)

The willow oak tree, which grows between 65 and 100 feet (20 and 30 meters) tall, has bark and leaves similar to other red oaks. When mature, willow oaks have a thick oblong crown and may grow 2 feet (0.6 meters) each year.

Oak tree bark: The rough gray-brown bark of willow oak trees becomes thin fissures as it ages, making them easy to identify.

Oak tree leaves: The leaves of the willow oak are lanceolate, thin, and pointed, with a smooth surface. Willow oak leaves help differentiate it from other red oak species. Willow oak leaves lack lobes or teeth, unlike other oak trees.

Coast Live Oak or California Live Oak Tree (Quercus agrifolia)

When the tree is young, it has smooth dark gray bark, and as it grows older, it sports dark green spiny leaves and tiny, egg-shaped acorns. The coast live oak tree (Quercus agrifolia) is a medium-sized spreading evergreen with smooth dark gray bark.

The gnarled branching and broadly rounded crown of the California live oak makes it easily recognized in a landscape. Live oaks reach 30 to 80 feet (10 to 25 meters) in height.

The slender egg shape with a pointed apex distinguishes coast live oak acorns. The acorn fruit is covered with a warty cupule one-third of the way down, and the nuts are dark reddish-brown to black. The acorns are ready to harvest in seven months, unlike other live oak species.

Coast live oak tree leaves look like holly leaves, according to images. An oval shape with spiky margins, the glossy green evergreen leaves are an unusual sight. Early spring sees the oak tree lose its leaves, and new ones appear shortly after. The leaves are 2 to 7 inches (0.8 to 2.7 cm) long and 1.5 to 2 inches (4 to 5 cm) broad.

The coast live oak’s pendulous yellow-green or yellowish-red clusters of blooms are 2″ to 4″ (5 – 10 cm) long when in bloom.

Coast live oak trees are spectacular specimen trees for USDA zones 9 through 11, with blooms that appear throughout the year. Shearing the tree to create an evergreen hedge is another option.
