Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

The California black oak is a deciduous tree that grows 30'-80' tall. It has sharply lobed, green leaves which turn yellow to orange in the fall. The black oak is a CA native, is drought tolerant, and attracts butterflies. It prefers afternoon shade in warm, inland valleys. It is a long lived tree; some are 500 years old!
