Dr. Todd West (North Dakota State University Plant Improvement Program) in collaboration with Dr. Mark Widrlechner (USDA-ARS North Central Regional Plant Introduction Station, Ames, IA) brought this oak to the marketplace. Originally thought to be English oak (Quercus robur), but now considered a hybrid between English oak and white oak (Quercus alba).
