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:

Consider replacing some lawn areas with groundcovers, trees, and shrubs.

Good candidates for removal are portions of large lawns, areas where no one uses the grass, patches that don't grow well, or spaces too small to water without overspray.
