Quercus engelmannii - Engelmann Oak, Mesa Oak
Engelmann Oak is a species of white oak native to Southern California. A moderately fast growing tree, it can reach a height of 65 feet with a 90-foot spread. The light grayish-brown bark is furrowed, and trunks develop a characteristic gnarled and twisted appearance as the tree matures. The tree has blue-green, leathery leaves and insignificant flowers followed by acorns. Mesa Oaks like full sun and dry soil but benefit being planted where roots can reach groundwater. Mostly evergreen, it may lose leaves in hot, dry months.
