Regal Prince oak (Quercus robur x Q. alba 'Regal Prince') is a hybrid oak tree that is known for its upright, columnar growth habit and attractive foliage. It is a deciduous tree that can reach a height of 50 to 60 feet (15.2 to 18.3 meters) and a spread of 15 to 20 feet (4.6 to 6.1 meters).
The tree has a narrow, upright form with a dense canopy of dark green leaves that turn yellow-brown in the fall. It produces acorns in the fall that are a food source for wildlife. Regal Prince oak is tolerant of a variety of soil types and can grow in full sun to partial shade.
Regal Prince oak is a popular tree for landscaping and is often used in urban areas due to its narrow form and ability to tolerate compacted soils. It is also resistant to oak wilt, a deadly fungal disease that affects many oak species.
