Quercus gravesii, commonly known as Chisos Red Oak, is a deciduous tree native to the canyons, hills, and limestone outcrops in the Chisos Mountains of Texas and northeastern Mexico. It typically grows to a height of 25-35 feet (8-11 meters) and a width of 20-30 feet (6-9 meters), featuring a rounded canopy with a moderate growth rate. The leaves of Chisos Red Oak are deeply lobed, turning shades of red and orange in the fall, which adds to its ornamental value. Its acorns are also an important food source for local wildlife.

Chisos Red Oak is valued for its adaptability to various soil types, including rocky or calcareous soils, and its ability to withstand drought conditions once established. It is suitable for use in xeriscaping, as a shade tree in residential landscapes, and for naturalistic plantings. While it thrives in full sun to part shade, it requires well-drained soils and can tolerate low to medium water conditions. Gardeners should be aware that, like many oaks, it can be susceptible to oak wilt, a serious fungal disease.CC BY-SA 4.0
