The Texas Red Oak (Quercus buckleyi) is the westernmost member of a group of closely-related oaks, in what is often referred to as the eastern Red Oaks. They are, roughly, named for their fall color, although not all have red fall color. Texas Red Oak certainly does. The leaves within this group are similar, leading to endless confusion that can only be cured by careful study. Each species is readily identifiable, though people rarely are willing to commit the needed effort. But, as with all oaks, hybrids do occur, testing the skills of even the most proficient horticulturists.
