The Southern Red Oak Tree: A Survivor
The southern red oak is a common sight in the southeastern United States, as it is not only abundant in natural habitats but also planted widely as a shade or ornamental tree. This is due, in part, to the tree’s rugged constitution, which allow it to thrive in harsh locations.
The southern red oak is fairly drought tolerant, and it’ll often grow in rocky or sandy soils in which other species can’t thrive.
Southern Red Oak Tree Identification: Tips & Tricks
The southern red oak can present some challenges to the budding nature lover, but they become fairly distinctive and easy to recognize with practice.
One of the reasons they can be tricky relates to the variability of their leaves. On a single branch, you may note three- and five-lobed leaves, and two to three different overall shapes. But there are two things you can look for that’ll generally help you identify a southern red oak: A curved (“falcate,” hence the specie’s scientific name) middle lobe and a bell- or vase-shaped base.
You can also note the distinctive two-toned appearance of the leaves, as this is sometimes helpful for distinguishing them from some other oaks. Most commonly, they’re dark, glossy green above and pale khaki or brown below.
It is important to note that the southern red oak can be very trick to distinguish from the cherry bark oak (Quercus pagoda) – a species that was formerly considered a different subspecies or variety of the southern red oak. However, the bell-shaped leaf base is generally sufficient to identify southern red oaks.
This species can also be challenging to distinguish from the blackjack oak (Quercus marilandica) at times, but blackjack oaks usually lack the curved appearance of the middle lobe.
