Two cultivars, 'Long' and 'Nadler' have recently been patented. The mother tree of both cultivars is an individual Quercus robur 'Fastigiata' (Upright English Oak, a cultivar with a narrow growth form) and grows in Jacksonville, Illinois.. Approximately 1000 seeds were collected from the mother plant in 1974 and propagated, with two selected for further development as cultivars, which are now propagated clonally.
The 'Long' cultivar is marketed under the trade designation Regal Prince.
The 'Nadler' cultivar is marketed under the trade designation Kindred Spirit. 'Nadler' oaks are 35 feet tall with a limb spread of 6 feet at an age of 30 years. 'Nadler' is highly resistant to powdery mildew, which plagues the Q. robur parent. This clone also exhibits heterosis (hybrid vigor).
