Quercus Douglasii:  

Blue Oak is native and endemic to California.  During the gold rush, blue oak was cut primarily for mining timbers and fuel wood.  It isn’t commonly used today as a commercial lumber as it is difficult to get lumber quality pieces, and it is difficult to dry properly – it likes to twist and turn.    But on the smaller scale, once dry, blue oak is quite attractive.  Many of the pieces we carry have a primitive rustic look.  Once dry, there is no reason not to try blue oak lumber for your projects.
