Aiming to fit into most gardens, this smaller, spreading oak has much more than that to recommend it: blue-tinted, wide, hollyesque leaves that become red-mahogany in late fall. This is the selection of Allan Taylor of Colorado who especially favors this among his 60 or so oak selections. It comes from ca. 4,800 ft in elevation in Colorado where its blue cast contrasts beautifully with the red-rock country of the Dolores River Canyon. Allan calls this "A once-in-a-lifetime discovery." It has been trialed here in the Northwest and shown to grow well here. And it's bound to look terrific with manzanitas and other chaparral plants.
