Types of Florida Oak Trees with Their Bark and Leaves – Identification Guide (Pictures)
Oak trees in Florida are an important part of the landscape. Many oak trees are native to Florida and grow throughout the Sunshine State. From the evergreen southern live oak trees that thrive in South Florida to the deciduous oak trees like the Shumard oak and willow oak in the north, you will find a wide variety of oak tree species.
Florida’s oak trees are some of the most beautiful and majestic trees growing in the state. The oak trees are identified by their vast, spreading crowns, thick trunks covered in rough, gray bark, leathery leaves, and acorns in varying shapes and sizes. Florida is home to many species of white oaks, red oaks, and the southern live oak tree.
This article is a guide to identifying the most common oak trees growing in Florida. Descriptions and pictures of oak trees in Florida’s landscape will help you recognize these stately deciduous and evergreen trees.
Florida Oak Tree Facts
Oak trees are flowering trees or large shrubs in the genus Quercus. Many species of oak trees are identified by their characteristic obovate or oblong leaves with deeply lobed margins. However, some species of oaks in Florida have leaves without lobes that look like willow or laurel leaves.
There are over 450 species of oak trees, 19 of which are native to Florida. The impressive large trees have an identifiable rounded or pyramidal crown, brown or black nuts in a warty cap, and leaves that grow spirally on woody branches.
Oak tree fruits are oval acorns with rounded or pointed tips. The smooth light brown to dark brown nuts sit in a scaly cap called a cupule. Mature oak trees only start producing acorns after growing for 20 to 30 years.
Common oak trees in Florida are divided into three categories — two are deciduous, and one is evergreen. Deciduous Florida oak trees are in the red oak and white oak groups. The live oak is a type of white oak, but it’s an evergreen Florida oak tree.
White and red oaks are generally found north of Orlando and Tampa, as well as in Florida’s panhandle. In addition, southern live oaks are found throughout Florida — from Miami and the Florida Keys in the South to Jacksonville and Tallahassee in Northern Florida.
Native Florida oak trees thrive in full sun and withstand the humid conditions in the state. Oaks suitable for northern Florida grow in USDA zones 5 to 9. However, some oaks are only cold-hardy in zones 9 and 10 and only grow south of Orlando.
Florida’s oak trees are famous for their tall stature with densely growing foliage that provides plenty of shade. Oak trees in Florida can grow between 60 and 100 ft. (18 – 30 m) tall and up to 135 ft. (41 m) wide.
Florida White Oak Tree
Florida white oak trees have smooth, obovate leathery leaves with rounded tips and lobes around the margins. The lobed tips don’t have the characteristic bristles of some red oak leaves. White oak acorns mature in six months and have a sweet or slightly bitter taste after leeching the tannins.
White oak trees in Florida typically grow 50 to 80 ft. (15 – 24 m) tall and wide.
Florida Red Oak Trees
Florida red oak trees are identified by their deciduous lobed leaves with bristled, pointed tips. Unlike white oaks, acorns growing on red oaks take two growing seasons to mature. The brown oval nuts have a very bitter and unpleasant taste. Red oaks in Florida typically grow 60 to 75 ft. (18 – 22 m) high and up to 45 ft. (13 m) wide.
Florida Live Oak Trees
Florida live oaks are evergreen trees, identified by their gnarled, horizontally growing branches and spreading, open crown. Live oaks have smooth, dark-green glossy, oblong leaves and small egg-shaped dark-colored acorns. The most common live oak species in Florida is the southern live oak, with its identifiable draping of Spanish moss hanging from branches.
In Florida, live oak trees typically grow up to 66 ft. (20 m) tall and 90 ft. (27 m) wide.
Florida Oak Tree Bark
Florida oak trees have smooth, silvery-brown bark when the tree is young. The bark develops deep grooves and raised ridges as the tree matures, giving a rough, fissured appearance and feel. Bark on Florida white oaks is typically light gray, and red oaks have dark, almost black bark.
Florida Oak Tree Leaves
The oak leaf shape and lobed margins help identify individual species of Florida oak trees. For example, white oaks have characteristic leaves with a broad, rounded apex and deep rounded lobes along the margins. Most red oak varieties have pointed lobes with bristled tips. In contrast, southern live oaks have smooth, thick leathery leaves.
Florida Oak Tree Acorns
Acorns on Florida oak trees are egg or barrel-shaped brown nuts growing in warty caps that are sometimes hairy. The oak tree acorns can be light tan to dark brown in color. The difference in shape is that some oak species have rounded oval acorns, and others have pointed almost triangular-shaped nuts.
Florida Oak Tree Flowers
Flowers on oak trees growing in Florida are slender yellowish-green stems with small clusters of flowers. The dangling male oak catkins differ from the female flowers that grow on the same tree. Female oak tree flowers are tiny reddish clusters growing on short stems. Oak flowers are described as inconspicuous.
Florida Oak Tree Identification
Identifying an oak tree in a Florida landscape is by its leaf shape, size and shape of the acorns, and type of bark. Its gray color and deep fissures identify oak tree bark. Leaves of deciduous oak trees have deep lobes, and some have bristled tips. Acorns are shades of brown and generally oval.
