Quercus robur x mongolica | Davis

Here can be seen foliage from the Shields Grove, of the English/Mongolian Oak hybrid (Q. robur x mongolica). These trees have proven surprisingly robust in the Grove, surviving for decades with little or no supplemental irrigation. The aphids and sooty mold which make English Oak a poor planting choice, have not been seen on this hybrid. A burst, or flush, of pinkish new growth is visible here, in the early stage of expansion.
