Drummond post oak is a medium-sized deciduous oak tree in the white oak group in the Fagaceae family native to North Carolina, western Louisiana and north Texas, although some sites say just Texas. It is a naturally occurring hybrid between the post oak and the sand post oak. It can be found growing in upland pine-oak forests and savannas over deep sandy soils, rarely clay soil.
Plant in full sun in well-drained sandy soils. Propagation is by seed.
The Drummond post oak has dark green, glossy lobed leaves. The spring flowers are followed by acorns each fall.
Use Drummond post oak as a shade tree and to attract wildlife.
