Quick Summary

The interior live oak (Quercus wizlizenii) is an evergreen oak native to western North America. It is similar to the coast live oak but is found in foothills away from the coast, forming a significant part of the chaparral. Like other live oaks, it retains its foliage year-round. This species, along with the California live oak (Q. agrifolia), typically has holly-like leaves and can be shrubby or grow to heights of 15-25 meters (50-82 feet).12
