Q. virginiana is a perennial tree of the Fagaceae family native to North America.
Q. virginiana is found along the southeastern coast of the United States from Texas to Virginia.
Q. virginiana is locally common to abundant in maritime forests and maritime scrub on barrier islands, more rarely inland (though regularly on the mainland from se. NC south, and extending substantially inland from s. SC south), sometimes in dry, fire-maintained habitats. Specimens have been collected from habitats that include upland woodland, sand ridge, shellmound, sandy loam, open woods, old field, flatwoods, hardwood hammock, pasture, upland field, live oak hammock, mixed woodland, coastal hammock, and mucky sands.
Q. virginiana increased its cover in response to soil disturbance by clearcutting and chopping in north Florida flatwoods forests. It has also increased its occurrence in response to agriculture in southwest Georgia pinelands. In these reestablished habitats that were disturbed by these activities, this species has shown regrowth.
Q. virginiana has been observed to flower in March, April, October, and November.
This species is thought to be dispersed by gravity.
Herbivory and toxicology
Quercus virginiana has been observed to host leafhopper species such as Empoasca fabae (family Cicadellidae), bees from the Membracidae family such as Archasia belfragei, Cyrtolobus tuberosus, Ophiderma definita, Smilia camelus and Telamona salvini, and plant bugs from the Miridae family such as Americodema nigrolineatum, Atractotomus miniatus, Hamatophylus guttulosus, Plagiognathus lineatus and Pseudoxenetus regalis, as well as Zelus luridus (family Reduviidae). Hummingbirds are attracted to Q. virginiana. They use the pollen to acquire energy in the spring before migrating. They will also eat insects on the tree and from spider webbs on the tree.
Conservation, cultivation, and restoration
Native Americans used the bark to create treatments for sore eyes and dysentery.
