With small, startlingly blue tinted foliage and modest stature, features not previously available commercially in an oak, Dolores River Southwest Heritage Oak™ is very desirable. The autumn change from blue to red-mahogany comes very late, November or December. It broadens the market for small trees by reducing the shortage of oak trees which can be grown without high maintenance costs in the arid West. Appropriate for small sites, arid locations and alkaline soils which cause many oaks to suffer chlorosis because of its region-adapted rootstock. This grafted form will grow with a single stem to 15-18 feet tall, with a 15-foot spread. It could easily be grown as a low branched spreading tree.
