12 Narrow Columnar Trees for Small Spaces
In landscaping, columnar trees provide both lovely foliage and a distinctive shape. Horticultural expert Lorin Nielsen reveals 12 of her favorites that you should consider.

Columnar trees add beautiful color and power to a landscape. They have their own spire-like beauty that provides a wonderful contrast against wide-spreading plants.
These narrow trees look formal and crisp in appearance. Their slender shape often makes them appear well-pruned and neat, even though they may not have been pruned in a while. Instantly, they add a bit of beauty and grace to a landscape.
These 12 columnar trees are perfect for narrow spaces, adding structure and elegance to your garden. But first, what exactly is a columnar tree?
What Is a Columnar Tree?
With columnar trees, you don’t need as much space for growth. Many have fastigiate branches, which means they grow almost straight up rather than out from the tree, narrowing the size of the tree’s canopy. This form of growth allows the foliage at the branch tips to reach sunlight easily.
Columnar trees are extremely effective as a windbreak. Planting a row of them creates a green wall that breaks up high wind and slows it as it rolls across your property. They’re also used as privacy fences since their foliage is often dense and thick.
In addition, columnar trees can be a dramatic garden feature. Planting along the length of a driveway makes for a stunning visual display, and a pair at either side of a porch can produce a dramatic, pillar-like effect.
How To Maintain Your Columnar Tree
Much of the process of pruning columnar trees is intended to enhance their upright growth habit. Since their branches do stay mostly upright, the goal is to reduce excess growth bending branches outward.
Examine any branch sections that are starting to curve outward. Is the branch itself thick enough to support the weight of its foliage? If not, look for a leaf node on the branch. These nodes provide a point from which new foliage can develop in the future.
Clip just above that node, leaving the node in place and removing excess leaf weight. Be sure to use sterile clippers.
Whip-like slender growth that can’t support its greenery is often the most common target of pruning. But what about columnar fruit trees which require older wood to fruit on? Be careful with these to maintain some of that necessary older wood.
If there are dead branches, those can and should be removed. Look to see whether any of the branch is still alive, and if so, try to keep the lower segment which is living. If not, remove it low on the tree to allow for other foliage to fill in space.
Most pruning of small trees for gardens will happen in the late fall or early spring. Select a time in which fruit trees and some other species are dormant if possible. If there are broken or wind-damaged sections at other times of the year, you can remove those as needed to prevent damage to the rest of the tree.
12 Columnar Trees For Tight Spaces
Whether you’re looking for edible narrow trees, something a little more compact, or tall species to make a statement, these are the ones to look out for.
Green Apple
botanical name Malus ‘North Pole’ | |
sun requirements Full sun | |
height 8-12 feet | |
hardiness zones 4-9 |
The ‘North Pole’ cultivar of columnar apple can grow up to 8-12 feet tall and 2-3 feet wide, and is perfect for USDA Zones 4-9. These are widely grown by home gardeners looking for an easy-care fruit tree. This deciduous tree also puts up a beautiful display of white flowers during spring.
The fruit is extremely juicy, crisp, and delicious and appears from late August through the entire month of September. Some grafted varieties can produce fruit even in their first year of growth!
Red Apple
botanical name Malus ‘Scarlet Sentinel’ | |
sun requirements Full Sun | |
height 8-12 feet | |
hardiness zones 4-9 |
The ‘Scarlet Sentinel’ cultivar of apple is a deciduous, super-narrow, beautiful specimen. Strong branch development is key here, as it has a lower number than other species. But that strength also supports its eventual fruit.
Brilliantly white, lovely flowers form in the spring. These white blossoms give way to sweet red apples that ripen in September. Like the other apple, it averages 8-12 feet tall and 2-3 feet wide.
Weeping Persimmon
botanical name Diospyros virginiana JN5 | |
sun requirements Full sun | |
height 10-15 feet | |
hardiness zones 5-9 |
As claimed by one seller, this tree will likely outlive you! The average lifespan of a weeping persimmon is 75 years, and in that time it can reach a height of 10 to 15 feet with a spread of only five to seven feet wide.
Unlike other columnar trees, the branching habit starts by pointing up and then deliberately curves downward, creating the ‘weeping’ form which provides its unique shape.
Thick, jade-colored leaves produce ivory-white flowers in the spring. As the seasons progress, the leaf color will develop some of the most lovely shades of autumnal brilliance you’ll see in a fruit tree.
Brilliant red, yellow, and orange leaves will fall, leaving behind only plump and sweet orange fruit in late October and early November.
Sky Pencil Holly
botanical name Ilex crenata ‘Sky Pencil’ | |
sun requirements Full sun to partial shade | |
height 4-10 feet | |
hardiness zones 5-8 |
Sky Pencil Holly, native to Japan, is one of the most beautiful trees for small gardens. The name itself reveals its slender shape. It is extremely narrow and can grow 4-10 feet tall with only a two foot width, but it can also be kept shorter through pruning and shaping.
Evergreen in USDA Zones 5-8, this lovely landscape tree is fairly low-maintenance. It seldom needs pruning unless you’re trying to keep it to a dwarf habit. It’s one of the smallest columnar trees you can find, but that in no way reduces its potent beauty.
Slender Hinoki Cypress
botanical name Chamaecyparis obtusa | |
sun requirements Full sun to partial shade | |
height 8-12 feet | |
hardiness zones 4-8 |
While technically not a true columnar tree, the slender Hinoki cypress grows in a similar fashion. Soft, green foliage forms a slender column that grows almost from the soil all the way up to the tip of the tree. It averages 8-12 feet tall with a spread of four to five feet wide.
Somewhat bushy at its base, it has been popular over the years for large-format bonsai. But even when not formally trained into detailed shapes, your cypress will provide a lovely minimal-space, good-height addition to your landscape in USDA Zones 4-8.
Skyrocket Juniper
botanical name Juniperus virginiana ‘Skyrocket’ | |
sun requirements Full sun | |
height 15-30 feet | |
hardiness zones 3-9 |
Hardy down to -20°F (-29°C), the skyrocket juniper can grow comfortably in USDA Zones 3-9. Native to North America, it’s prized for its blue-green foliage and ability to create a stunning privacy screen.
When mature, the skyrocket juniper easily hits heights of up to 30 feet with a two to three foot spread. Its evergreen foliage is similar to other juniper species but with an added bonus. This species almost never requires pruning or detailed maintenance to keep it in shape.
Spartan Juniper
botanical name Juniperus chinensis ‘Spartan’ | |
sun requirements Full sun | |
height 15-20 feet | |
hardiness zones 4-9 |
Tolerant to drought, a wide range of temperatures, and salt spray, the spartan juniper is one of the most popular upright and narrow junipers available today.
Its deep green foliage provides plenty of color as a garden screen or windbreak. The dense-packed branch development on this plant effectively blocks anything from seeing through it.
In addition, junipers as a whole are pest resistant, which means you’re not going to be constantly spraying it down to keep it going. Hardy and easy to grow in either partial or full sunlight, this plant is best in Zones 4-9. It easily hits 15-20 feet tall and four to five feet across in size.
American Arborvitae
botanical name Thuja occidentalis | |
sun requirements Full sun to partial shade | |
height 10-40 feet | |
hardiness zones 3-7 |
The rounded conical shape of the American arborvitae is perfect as a privacy fence for your garden. In addition, it’s a visual stunner, reaching heights of up to 40 feet with a maximum five-foot spread at its base. A row of these can make for a stunning peaked display.
Emerald Green
botanical name Thuja occidentalis ‘Smaragd’ | |
sun requirements Full sun | |
height 12-14 feet | |
hardiness zones 3-7 |
The scaly leaves and fan-like branches are covered with a rich, red-brown bark. When it produces seed cones, they’re narrow and yellowish-green in color.
It’s tolerant of most soil types, and is low-maintenance to keep going. Of the arborvitae species, I love the narrow-tipped look of this one best.
Brodie Eastern Red Cedar
botanical name Juniperus virginiana ‘Brodie’ | |
sun requirements Full sun | |
height 45 feet | |
hardiness zones 3-9 |
With one of the widest growing ranges of the columnar tree species we’re covering today, Brodie can be grown in Zones 3-9 outdoors. It’s hardy down to -30°F (-34°C), yet tolerates the warm and balmy climates of southern California as well. Best of all, this species can tolerate most levels of humidity from wet to incredibly dry with no problem.
The Brodie’s feather-like foliage is very self-maintaining. Little to no pruning is required to care for this tree. And if you want it to soar, it can. The Brodie can reach a maximum height of an astonishing 45 feet, with up to a 10-foot width. Kept pruned, it will stay at a more manageable height if you’d prefer.
Eastern red cedars provide lots of brilliant greenery in a densely packed space. You’ll love the beauty that the Brodie can offer.
Italian Cypress
botanical name Cupressus sempervirens | |
sun requirements Full sun | |
height 40-70 feet | |
hardiness zones 7-10 |
The Italian cypress is a true columnar variety, narrow in width and perfect for a myriad of uses. Their maximum width at full height is 5 feet, but if kept shorter they stay a narrow 2-3 feet wide at most.
While they can achieve heights up to 70 feet if left to their own devices, they can be topped and maintained at a shorter height as well.
These are great for container or planter growing, and their lush green foliage thrives in full sun conditions. They perform the best in Zones 7-10, and as a result, are a common sight in residential developments throughout the southwestern US.
Lombardy Poplar
botanical name Populus nigra | |
sun requirements Full sun | |
height 40-70 feet | |
hardiness zones 2-10 |
Have you ever driven past a large property with a towering line of trees along one side? They might be lombardy poplar, particularly if they stand between 40-70 feet in height.
These lovely poplar trees can form a large, solid barrier that makes them a prime candidate for windbreaks. They’re even used to prevent topsoil from blowing off farms.
Due to their height, they’re also astonishingly effective as shade trees. Planted eight feet apart, they intertwine to form a dense visual barrier as a living privacy screen. If you’re looking for something massive to create a living, woody boundary in Zones 2-10, this is a great choice.
Colorado Blue Spruce
botanical name Picea pungens | |
sun requirements Full sun to partial shade | |
height 30-60 feet | |
hardiness zones 2-7 |
Last but certainly not least on our list is the Colorado blue spruce. This gorgeous coniferous evergreen has silvery blue-green needles and a conical growing habit. It’s the most adaptable to cold conditions of our recommended columnars, tolerating chill weather down to -40°F (-40°C). Most often, it’s grown in Zones 2-7.
Most people think of spruces in terms of a Christmas tree, and this one has that rounded conical habit. But due to its deep root system, it resists high winds well, and it’s low-maintenance.
As it grows throughout the year, you’re treated to a lovely silvery-blue shade which stands out in landscaping. In the fall, you’ll also have 3-inch cones appearing in the upper crown of the tree.
While it grows to reach 50-75 feet in height in the wild, it can be maintained as a much smaller specimen, even as short as 10-12 feet. The top of the tree is narrow, but as it cascades downward, it widens to a pleasing base.
Final Thoughts
These narrow trees are perfect for squeezing into tight spaces. Use them to create a privacy screen, a windbreak, add height to your garden, or simply for their aesthetic value.
