Answer: Quercus engelmannii (Mesa Oak, Engelmann Oak,or Pasadena Oak) is an evergreen tree, spreading to 50 fit high and often twice as wide. Its thick leathery green leaves are up to 2 inches long and oval to cylindrical; round-tipped acorns are to 1-? inches long. It does best with monthly deep soakings in the warm season, but don?t keep it constantly moist. It grows well in your area and provides terrific shade.
