Discussion

The wood of Quercus imbricaria was once an important source of shingles, hence its common name.

The Cherokee used the bark of Quercus imbricaria to treat indigestion, chronic dysentery, mouth sores, chapped skin, general sores, chills and fevers, lost voice, milky urine, and as an antiseptic and a general tonic (D. E. Moerman 1986).

This species reportedly hybridizes with Q. coccinea (W. H. Wagner Jr. and D. J. Schoen 1976); with Q. falcata (producing Q. ×anceps E. J. Palmer) and Q. ilicifolia (D. M. Hunt 1989); with Q. marilandica, Q. palustris, and Q. phellos (H. A. Gleason 1952); and with Q. rubra, Q. shumardii, and Q. velutina.
