Description This tree is found in central and southeastern Arizona where it is an important member of grassland and oak woodland plant communities. It is relatively easy to identify with its lightly serrated, evergreen, dark foliage. Plants can range in size from bushy plants 10 ft. high to 30-60 ft. giants with beautiful canopies. The acorns mature before most other species and serve as an essential food source for wildlife and people, especially because the acorns are relatively low in tannins (distasteful chemicals). Emory oak will require more moisture at lower elevations, but it is a drought tolerant tree in cooler gardens. Plant with mountain mahogany (Cercocarpus breviflorus), juniper (Juniperus deppeana), and lemonade berry (Rhus aromatica).
