In its natural habitat it grows in the valleys and lower slopes of the Coast Ranges, the lower western foothills of the Sierra Nevada, and the north slope of the San Gabriel Mountains. The Scottish biologist David Douglas first named the blue oak in 1831 for the bluish color of its leaves. The blue oak is a short tree with an open canopy. The canopy is typically rounded with many crooked branches. The tree grows to average heights of 30-50 feet high and 40-70 feet wide. In deep, moist soil it can grow up to 60 feet. It is a winter deciduous tree, but will sometimes shed its leaves during severely hot and dry years and go dormant. This tree is does well in dry, hot situations and is immune to sudden oak death. It is recommended for zones 3-11 and 14-24.
