Quercus x comptoniae | Visalia

As mentioned, Southern Live Oak (Quercus virginiana) shows relatively little hybridization by comparison to other types of oaks. But hybrids certainly do occur, and the Compton's Oak (Quercus x comptoniae or Quercus virginiana x lyrata) is by far the most common and best known. Compton's Oak is a unique hybrid, with one parent being a semi-evergreen species, while the other parent, Overcup Oak (Quercus lyrata) is a deciduous species with leaf drop taking place relatively early in the fall. This make the Compton's Oak hybrid quite variable, even for typically variable oak hybrids. Here we see a pair of Compton's Oaks in Visalia, planted nearly a decade before this picture was taken.
