    This oak tree from East Asia is a pretty tree of good quality. It has dark, shiny, chestnut-like leaves to about 7 inches long with bristle-tipped marginal sharp teeth. Acorns get about 1 inch long. It is resistant to drought, heat, and humidity. It does develop micronutrient chlorosis in alkaline soils, and its pH range is good from pH 6 to 7; not sure how much farther.

    My concern is that its large acorns can help the species escape cultivation and it can become another invasive Asian species. I've seen it planted in parks and public places occasionally in the Philadelphia area. Being in parks surrounded by lots of lawn or being in very urban spots probably is not a bad situation. I would prefer to use the similar Shingle Oak, (Quercus imbricaria), that is a native species in eastern North America. It has escaped cultivation in various spots : about half of Louisiana; spots in MS & AL & north GA, MD, DE; 3 spots around St Louis, MO; 3 spots in OH, 2 spots in PA, 1 spot in CT, 1 spot in central IN, and 1 spot in northern NC.
