Leather Oak
Quercus durata var. durata
  
About Leather Oak (Quercus durata var. durata) 1 Nurseries Carry This Plant Quercus durata var. durata is the most common variety of Leather Oak. It tends to grow at elevations from 500-4900 feet, primarily in the central Coast Ranges. The other variety, var. gabrielensis, is a rare plant restricted to the Transverse Range. Leather oak is often found on serpentine soils. However, in the garden this plant does not require serpentine soil and can tolerate garden soil as well as drought and clay-rich soils. However, it is best adapted to relatively dry, rocky, nutrient-poor soil. Most individuals remain short, under 15 feet, and have small, densely organized leaves.
