Regal Prince Oak (Quercus robur 'Regal Prince'), also known as Quercus x warei 'Long' Regal Prince, is a hybrid English and Swamp White Oak prized for its upright columnar form, mildew-resistant foliage, and strong tolerance to urban conditions. Bred for structure and reliability, this cultivar performs well in both formal designs and challenging city environments.
