94-07 A) There are several Ware’s oak trees (Quercus ×warei) here at Oak Ridge, planted as an experiment to evaluate the variability and adaptability of this hybrid. Look for other conspicuously narrow oaks especially in the western half of Oak Ridge. They resulted from crossing the upright English oak (Quercus robur ‘Fastigiata’) with swamp white oak (Quercus bicolor).
94-07 B) Ware’s oak (Quercus ×warei) is a cross of the upright pedunculate oak (Quercus robur ‘Fastigiata’) with our native swamp white oak (Quercus bicolor). This specimen was grown from the Riverbank Oak in Petersburg, Illinois, a registered oak cultivar which has produced several other superior upright oak cultivars including ‘Windcandle’ as well as the colorful compound (with Q. alba) crosses ‘Chimney Fire’, and Birthday Candle’. Other cultivars from the same cross also are available in the nursery trade. The best ones combine the upright form of the European tree with the disease resistance of the American one.
