Logue oak is a naturally occurring hybrid of the red oak, Q. rubra, and the shingle oak, Q. imbricaria, in the Fagaceae family. It can be found on moderately dry to mesic slopes and uplands of the central and northeastern United States.
Grow in full sun in well-drained, moist to dry soils. It is adaptable to most soil types. Propagation is by seed.
Leaves can vary from being lobed to nearly entire to coarsely toothed. Acorns mature the second year, as do most red oaks.
Logue oak can be used as a shade or street tree.
