Height 20 - 40 (60 ft.)
Spread equal or more
Growth Rate slow - moderate
 
Environment:
Exposure full sun - prefers warm sunny locations; can tolerate some shade
Soil prefers well-draining sites; can tolerate clay if not over-watered
Hardiness hardy (zones 5-9, 14-24): thrives in more habitats than other oaks

a good small to medium-sized shade tree, valued for its durability and greater tolerance of different soils/habitats than other oaks; suitable for use in woodlands or Mediterranean-theme gardens
 
Landscape Care:
Watering tolerates regular if drainage is good; is quite drought-tolerant after established; thrives with an occasional deep-soaking in summer
Fertilizing little needed unless if frequently watered
Pruning head high and thin canopy to develop more attractive branch structure
Pests/Diseases quite disease-free compared to some other oaks
Special Conditions/Other can become an accent tree for form if structure is developed by pruning
