The leaf margin contains 7 to 9 bristle-like tips that are often subdivided into secondary lobes. The Texas red oaks, along with the previously mentioned close relatives, are deciduous. Probably the most endearing trait is the brilliant scarlet fall color displays. Once triggered by cool temperatures and shorter days, spectacular color may be expected. This brings up the least desirable trait, which is the removal of leaf litter, but the color is well worth it.
Flowers adorn the trees prior to or during leaf emergence.
Female flowers are solitary or in pairs. The acorns of this species occur on a biennial basis as each requires two years to mature. The Texas red oak is native to the rocky limestone hills of central Texas. Although typically found in alkaline soils, specimens do occur in neutral and slightly acid soils. The plant appears to be more drought tolerant than the Shumard oak, which is found more commonly in rich, moist soils.
