Quercus mohriana, commonly known as Mohr Oak, is a versatile plant that can be an evergreen or deciduous tree or shrub, depending on environmental conditions. It is native to limestone hills, canyons, and arroyos in the South Central United States and Northern Mexico. This species exhibits significant variability in form, sometimes growing as a small tree up to 20 feet (6 meters) high or as a large, thicket-forming shrub. The bark of Mohr Oak is light brown, rough, and deeply furrowed, providing textural interest. The inflorescence, which appears in spring, is reddish and consists of female catkins with one to three flowers and male catkins with numerous flowers, though they are not particularly showy. The acorns, however, are a food source for wildlife.

Mohr Oak is drought-tolerant and thrives with low amounts of water, making it suitable for xeriscaping and naturalistic plantings in arid regions. It adapts well to full sun or part shade and prefers soils with medium to fast drainage. In cultivation, it is valued for its adaptability, use as a windbreak, and its ability to form dense thickets for habitat restoration or erosion control. While not commonly used in ornamental horticulture, it can be an interesting specimen in native plant gardens or in reforestation projects. Care should be taken in urban settings, as its thicket-forming habit may not be suitable for all landscapes.CC BY-SA 4.0
