Description

Blue Oak is a deciduous tree that has a slow growth rate and reaches 50 ft. high. It develops 2" long, lobed blue-green leaves. Blue Oak is very drought tolerant, is native to California and attracts butterflies. Because of its slow growth, it can be used for bonsai. Flowers are insignificant. Acorns were used by California Natives for food.

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.
