15-4 Bimundor oak, literally the oak of two worlds, Quercus ×bimundorum is not found in nature. North American white oak ( alba, the Illinois state tree) has pollinated an isolated cultivated specimen of the upright European pedunculate oak (Q. robur ‘Fastigiata’) to produce this tree. The natural ranges of the two parent species are separated by thousands of miles of the Atlantic Ocean. While the European parent was narrowly upright, that trait was not inherited by our tree, which is growing normally with an open, spreading habit. The parent species each are among the longest-living oaks on their respective continents.
