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.
