Quercus greggii, commonly known as Mexican Oak, is a semi-deciduous tree native to the high-altitude oak-pine forests and oak woodlands of Mexico, particularly thriving at altitudes between 6,600 and 10,800 feet. It typically attains a height of 20-25 feet and a spread of 10-15 feet. The leaves are distinctive for their waxy texture and coverage with trichomes, which are fine outgrowths or appendages on plants. Mexican Oak’s bark is noteworthy for its light gray color and the presence of lenticels, which are small corky spots that allow for gas exchange between the atmosphere and the internal tissues of the tree. In April, the tree produces male catkins and female inflorescences, which are followed by the development of acorns. The cultivar ’La Siberia’ is recognized for its particular traits.

Mexican Oak is valued for its adaptability to high-altitude conditions and its unique leaf texture, which adds interest to gardens. It is suitable for use in urban settings, particularly in areas with similar altitude and climate to its native range. In cultivation, it requires well-drained soils and can tolerate dry conditions once established. It prefers full sun to part shade. While not widely available, the ’La Siberia’ cultivar may be sought after for its specific characteristics. Gardeners should be aware that semi-deciduous trees like the Mexican Oak may require occasional cleanup of fallen leaves.CC BY-SA 4.0
