The Perfect Columnar Oak for Modern Landscapes and Privacy Screening
Regal Prince® Oak gives you the stature, shade, and long-term value of an oak tree without the wide horizontal spread that most oak trees require. Its narrow, upright habit makes it an excellent choice for urban landscapes, suburban yards, driveway borders, privacy rows, and tight spaces where a full-size shade tree would normally be too broad.
The Regal Prince Oak is ideal for urban landscapes due to its columnar shape, making it suitable for narrow spaces and providing a formal look when planted in rows. This regal prince oak tree brings classic oak character-glossy foliage, acorns, strong branching, and seasonal color-while staying compact enough for modern landscape plans.
If you want an oak with presence, screening, and structure, but you do not have room for a massive low canopy or sprawling crown, Regal Prince is built for that space.
Why You'll Love It
-
Mildew-Resistant Foliage – Regal Prince Oak's glossy, green summer foliage is mildew-resistant, making it a low-maintenance option for landscaping in various climates.
-
Space-Efficient Design – The Regal Prince Oak typically reaches a mature height of 40 to 60 feet and a spread of 15 to 25 feet, making it suitable for smaller landscape areas.
-
Fast Growth Rate – This hybrid oak tree is known for its vigorous growth rate and unique columnar form, which allows it to thrive in urban landscapes with limited space.
-
Exceptional Hardiness – This oak tree is known for its excellent winter hardiness and can tolerate wind and ice, making it suitable for various climates.
-
Low Maintenance – Regal Prince Oak thrives in full sun and can adapt to a variety of soil conditions, including both normal and dry soils.
Regal Prince Oak is known for its glossy, dark green leaves that are resistant to mildew and provide a striking visual contrast with their two-toned appearance. The foliage is dark glossy green on top with a striking silvery-green underside, then turns golden-yellow in autumn for added seasonal interest.
What Makes It Different
Most oak trees need a large yard, broad open ground, and decades of waiting before they become practical shade or screening trees. Regal Prince is different because it keeps the oak form tall, narrow, and controlled, making it useful where traditional oak trees would overwhelm the space.
Regal Prince® Oak provides:
-
Hybrid Vigor – The Regal Prince Oak (Quercus x warei) is a hybrid tree resulting from a cross between the fastigiate English Oak (Q. robur f. fastigiata) and the Swamp White Oak (Q. bicolor).
-
Columnar Architecture – Its upright, fastigiate english oak influence helps the tree maintain a narrow, straight, columnar shape with minimal pruning.
-
Urban Toughness – The Regal Prince Oak is resistant to powdery mildew and can adapt to a wide range of soil conditions, including both wet and dry environments.
Its parentage combines quercus robur, quercus robur fastigiata, quercus bicolor, and swamp white oak strength into one extremely tough hybrid oak. Selected by Earl Cully in Jacksonville, Illinois, the patented cultivar ‘Long’-often listed as Quercus x warei ‘Long’ or warei long-was developed for durability, form, and landscape performance.
This oak tree is often used for screening and wind breaking, as its dense foliage can block unsightly views and reduce noise from traffic. It is a smart option for communities, commercial sites, narrow streets, and residential yards where long-lasting landscape structure and shade trees all matter.
How To Grow Regal Prince Oak Successfully
-
Plant in Full Sun
Choose a location with full sun, good soil moisture during establishment, and enough room for the expected mature spread. Regal Prince Oak thrives in full sun and can adapt to a variety of soil conditions, including both normal and dry soils. -
Watch It Establish
Once planted, mulch around the base, keep the root zone moist but not waterlogged, and feed Regal Prince Oak once a year with a slow-release fertilizer to promote healthy growth. The tree transplants well for an oak and begins putting energy into fast vertical growth as it settles in. -
Enjoy the Results
Over time, Regal Prince develops into a tall, narrow shade tree that can provide screening, wind protection, seasonal interest, and strong architectural structure, pairing well with evergreen privacy trees for year-round screening. For privacy screening, the trees should be spaced 7 to 10 feet apart; standalone specimens require 15 to 20 feet of clearance.
For best long-term health, prune only when needed and preferably during dormancy to reduce oak wilt risk. Young trees may need trunk protection from deer browse, mower damage, or wind exposure while they establish.

Frequently Asked Questions
How fast does Regal Prince Oak grow?
Regal Prince Oak has a vigorous growth rate for a columnar oak, especially when planted in full sun with consistent soil moisture during establishment. In favorable soil conditions, it can put on strong vertical growth each season and become useful for screening within 5 to 10 years.
Will it stay narrow or spread out over time?
Yes, Regal Prince Oak is known for its narrow, columnar shape. As it reaches maturity, the crown may become slightly more oval, but it remains far more space-efficient than most oak trees. For privacy screening, the trees should be spaced 7 to 10 feet apart; standalone specimens require 15 to 20 feet of clearance.
What soil conditions does it prefer?
Regal Prince Oak adapts well to many soil types. It is adaptable to various soil types including rich, moist loams, heavy clay, and sandy soils. It also performs in both wet and dry environments once established, though young trees benefit from steady moisture and mulch.
Is it deer resistant?
Mature Regal Prince Oak is generally durable, but young plants may be browsed by deer. The tree produces 1-inch oval acorns that provide food for local wildlife, so it supports birds and mammals while adding long-term ecological value to the landscape.
When is the best time to plant?
In California and many other regions, late fall through winter is often ideal because cooler weather and seasonal rain help roots establish before spring growth. November through early spring is a strong planting window in many yards, while warmer areas may also plant in early spring with irrigation. Avoid summer planting unless you have a solid watering plan.
Does Regal Prince Oak need pruning?
Minimal pruning is expected. Remove damaged or crossing branches as needed, but avoid heavy pruning during active growth because oak wilt can enter through fresh wounds. If the tree must be pruned, schedule the work during dormancy.
Ready to Transform Your Landscape?
Choose Regal Prince® Oak for a tall, narrow, mildew resistant, extremely tough shade tree that brings structure, screening, and classic oak beauty to modern landscapes.

Columnar Architecture – Its upright, fastigiate english oak influence helps the tree maintain a narrow, straight, columnar shape with minimal pruning.
-
Urban Toughness – The Regal Prince Oak is resistant to powdery mildew and can adapt to a wide range of soil conditions, including both wet and dry environments.
Its parentage combines quercus robur, quercus robur fastigiata, quercus bicolor, and swamp white oak strength into one extremely tough hybrid oak. Selected by Earl Cully in Jacksonville, Illinois, the patented cultivar ‘Long’-often listed as Quercus x warei ‘Long’ or warei long-was developed for durability, form, and landscape performance.
This oak tree is often used for screening and wind breaking, as its dense foliage can block unsightly views and reduce noise from traffic. It is a smart option for communities, commercial sites, narrow streets, and residential yards where long-lasting landscape structure and shade trees all matter.
How To Grow Regal Prince Oak Successfully
-
Plant in Full Sun
Choose a location with full sun, good soil moisture during establishment, and enough room for the expected mature spread. Regal Prince Oak thrives in full sun and can adapt to a variety of soil conditions, including both normal and dry soils. -
Watch It Establish
Once planted, mulch around the base, keep the root zone moist but not waterlogged, and feed Regal Prince Oak once a year with a slow-release fertilizer to promote healthy growth. The tree transplants well for an oak and begins putting energy into fast vertical growth as it settles in. -
Enjoy the Results
Over time, Regal Prince develops into a tall, narrow shade tree that can provide screening, wind protection, seasonal interest, and strong architectural structure, pairing well with evergreen privacy trees for year-round screening. For privacy screening, the trees should be spaced 7 to 10 feet apart; standalone specimens require 15 to 20 feet of clearance.
For best long-term health, prune only when needed and preferably during dormancy to reduce oak wilt risk. Young trees may need trunk protection from deer browse, mower damage, or wind exposure while they establish.

Who It's For
Ideal for:
-
Homeowners with narrow lots needing vertical screening
-
Urban property owners wanting classic oak trees in limited space
-
Landscapers designing privacy solutions for modern neighborhoods
-
Anyone seeking a low-maintenance, fast-growing shade tree
Regal Prince is an excellent choice if you want to provide screening without crowding your yard, driveway, patio, or property line. It also works well in small groups where a formal look is desired, especially when planted in rows for privacy or wind reduction.
Use this oak when you want the appearance of a traditional oak tree, the toughness of swamp white oak, and the narrow outline of fastigiate english oak in one landscape-ready plant, or when you’re pairing it with Cork Oak (Quercus suber) in Mediterranean-style designs.
Frequently Asked Questions
How fast does Regal Prince Oak grow?
Regal Prince Oak has a vigorous growth rate for a columnar oak, especially when planted in full sun with consistent soil moisture during establishment. In favorable soil conditions, it can put on strong vertical growth each season and become useful for screening within 5 to 10 years.
Will it stay narrow or spread out over time?
Yes, Regal Prince Oak is known for its narrow, columnar shape. As it reaches maturity, the crown may become slightly more oval, but it remains far more space-efficient than most oak trees. For privacy screening, the trees should be spaced 7 to 10 feet apart; standalone specimens require 15 to 20 feet of clearance.
What soil conditions does it prefer?
Regal Prince Oak adapts well to many soil types. It is adaptable to various soil types including rich, moist loams, heavy clay, and sandy soils. It also performs in both wet and dry environments once established, though young trees benefit from steady moisture and mulch.
Is it deer resistant?
Mature Regal Prince Oak is generally durable, but young plants may be browsed by deer. The tree produces 1-inch oval acorns that provide food for local wildlife, so it supports birds and mammals while adding long-term ecological value to the landscape.
When is the best time to plant?
In California and many other regions, late fall through winter is often ideal because cooler weather and seasonal rain help roots establish before spring growth. November through early spring is a strong planting window in many yards, while warmer areas may also plant in early spring with irrigation. Avoid summer planting unless you have a solid watering plan.
Does Regal Prince Oak need pruning?
Minimal pruning is expected. Remove damaged or crossing branches as needed, but avoid heavy pruning during active growth because oak wilt can enter through fresh wounds. If the tree must be pruned, schedule the work during dormancy.
