Quercus laurifolia apparently flowers two weeks earlier than sympatric Quercus hemisphaerica (W. H. Duncan and M. B. Duncan 1988). It reportedly hybridizes with Q. falcata, Q. incana, and Q. nigra (H. A. Fowells 1965); with Q. hemisphaerica, Q. marilandica, Q. myrtifolia, Q. phellos, and Q. shumardii (D. M. Hunt 1989); and with Q. velutina.
