7 Ornamental Trees for Zone 4
1. Aesculus Pavia – Dwarf Red Buckeye
It is one of the first flowering trees to sprout leaves in the springtime, a month before oaks and maples. However, the autumn foliage is among the first to fall, and its colors do not alter.
One of the earliest sources of food for hummingbirds is these early blossoms. However, particularly in zone four, the early blooms may be vulnerable to late frosts. While the tree is still relatively young, it will flower.
For optimal flowering, grow the plant in full to mainly sunny environments. The small tree can be cultivated as a multi-trunk tree or a huge shrub. It forms clumps. To keep a tree’s shape, prune lower lateral branches – an excellent tiny ornamental tree for a patio or forest garden.
- Hardiness Zone: 4-9
- Full sun to some partial shade
- 10 to 20 inches tall
- 10 to 20 inches wide
- Crown with a rounded, thick shape
- Growth Rate: Moderate to Slow
- Prefers moist, well-drained soil that has been intensively farmed.
- Requirements for moisture range from average to high.
- Large, drooping, dark green leaves with five leaflets have a gritty feel.
- Fruit trees: In the fall, leathery capsules.
2. Amelanchier Canadensis – Shadbush
Even among botanists and those who work in the nursery industry, there is some misunderstanding about the Shadbush tree. It is frequently confused with the Downy Serviceberry, Amelanchier Arborea. The sole distinguishing difference between them is that the Downy Serviceberry flowers are a little earlier to blossom and have more giant flowers.
Most Shadbush and Downy Serviceberry plants and bushes have many stems. It can easily be kept in tree form with little pruning of the trunk line and shoots. The most similar tree structure of the serviceberries is the downy kind. Early in the spring, white vertical clusters of flowers appear just as the leaves open.
Despite the short bloom season, the floral display is spectacular. The blooms give place to tiny, showy, crimson or blue-black fruits and draw birds. One of the earliest trees to change color in the fall is the bright green foliage, which turns dazzling yellow-orange or red.
If possible, filtered shade and moist to damp soil are preferred by Amelanchier Shadbush and Downy Serviceberry. However, they are highly adaptive to drier soil if given enough water when growing.
Amelanchier’s Grandiflora variety “Autumn Brilliance” does not consistently develop root suckers. Amelanchier often doesn’t suffer from a major disease or pest issues. Rust, leaf spot, powdery mildew, leaf miners, borers, or scale may, on occasion, cause problems.
Deer usually don’t bother Amelanchier. Amelanchier has an incredible shape that looks great in a shrub border or a shaded woodland environment. This would be an excellent choice for street planting because it can tolerate some salt and pollutants.
- Zones: 3-7
- Full sun to some partial shade
- Size: 10 to 25 feet
- Span: 10 to 25 feet
- Shape: Upright branches and a rounded, bushy crown.
- Moderate growth rate
- Moist, well-drained soil with a pH between neutral and acidic is preferred. Able to handle sand, clay, or loam
- Average water requirements and moderate drought tolerance
- Foliage: Elliptic-toothed, glossy-green leaves that are young are white and fluffy.
- Fruit: Edible, dazzling fruit
3. Amelanchier X Grandiflora – Autumn Brilliance
A hybrid Apple Serviceberry tree called “Autumn Brilliance” is also called a Juneberry tree. You can let it grow into a shrub or periodically cut the new shoots that sprout from the trunk.
It is rather simple to sustain the shape of this Serviceberry, which is frequently marketed as a tree with one or more trunks. Early blooming ‘Autumn Brilliance’ produces drooping clusters of softly aromatic white blooms having pink undertones that eventually turn white.
The blooms are bigger than the original Serviceberry hybrid, making a magnificent early-spring show. Tiny, spherical berries follow the blooms. While the fruits are fully developed, they have a deep purple-black color after first turning red when they are young. The berries are delicious.
The leaves start purplish, turning blue-green in the summertime, and a beautiful orange-red in the fall. ‘Autumn Brilliance’ is a superb exhibit tree in the home environment due to its exceptional decorative qualities from spring through fall. It is a tiny decorative plant enough to fit well in a shrub border.
Despite the need to occasionally prune new growth and suckers, it is generally simple to cultivate and maintain. Pruning must be done during the winter or early in the spring, even if it is not usually necessary.
Although it has excellent disease resistance, it can occasionally come under attack from aphids or leaf miners. This strong tree is somewhat salt-tolerant and hardy enough to be used in planting strips up to 6 feet wide or in the street boulevard. Depending on the environment, “Autumn Brilliance” will reach 10 feet in five to ten years.
- Zones: 3B-8
- Full sun to some partial shade
- Size: 15 to 25 feet
- Span: 15 to 25 feet

4. Amelanchier Laevis – Allegheny Serviceberry
Allegheny Serviceberry is a multi-stemmed shrub or tree that can thrive in full sun or partial shade. In full sun, blooming will be at its peak. The crown shape will appear more broad and graceful in areas with greater shadow. Once it has grown well, Allegheny Serviceberry will become more resilient to brief droughts.
This plant should grow tall and quickly in regularly moist soil. It is indeed possible that this Serviceberry might grow to be 30 to 40 feet wide and tall in ideal circumstances. Before the leaves appear, fragrant white blossom clusters appear, and in the summer, they are replaced by berries.
Juneberry is a common name for berries because they reach full maturity in June and change from bright red to purple to a deep purple-black. The edible berries are juicier than those from Amelanchier Arborea and are a good supplier of iron and copper. The fruit tastes a lot like blueberries.
The leaves have dense, delicate branching and start as bronzed purple before maturing into the lustrous green. Autumn causes the leaves to become red, yellow, or orange.
Serviceberry can be slightly susceptible to disease and pest issues, but not to the point where they pose a severe threat. Allegheny Serviceberry is fairly simple to grow and adds beauty to the landscape all year. In the spring, the flowers will draw bees and butterflies, and the berries will draw birds, reducing the amount of berry litter.
Amelanchier Arborea Downy Serviceberry and Allegheny Serviceberry are quite similar. Allegheny Serviceberry differs simply in having a smooth, hairless leaf, purple-bronze new growth, and a sweeter, juicier berry.
Allegheny Serviceberry is an attractive option for shrub borders, forest edges, or accent trees because of its delicate texture and graceful appearance. It can tolerate some urban pollutants and salt in the air and soil and will thrive as a street or boulevard tree.
The best way to preserve a tree form is to buy one that has already been pruned into a tree form. They will grow to be a tall informal hedge or privacy screen if planted 10 to 20 feet apart in shrub form and left unpruned.
- Hardiness Zones: 4-9
- Full light, partial shade, and shadow
- Size: 15 to 25 feet
- Span: 15 to 25 feet

- Lightly aromatic tiny white blooms appear in hanging clusters in April or May.
- Fruit: Edible, dazzling fruit
5. Aesculus X Carnea “Briotii” – Ruby Red Horse Chestnut
Compared to Red Horse Chestnut, Ruby Red Horsechestnut is slightly smaller. The flower bunches are bigger than the cultivar and have a rich crimson color. It is less prone to fungus-related illness.
Ensure the tree receives enough moisture during dry spells to prevent leaf burn and an overall loss in the tree’s health. Once established, “Briotii” produces a tap root, making it extremely difficult to transfer.
Often weak and delicate, the wood can crack under the pressure of a lot of snow. To promote a sturdy structure, prune internal crossed or wandering branches.
Horse Chestnut bleeds heavily and needs to be clipped in the middle of the summer after the new growth has grown and the blooming season is through—a widely used kind of Aesculus.
- Zones: 4-8
- Full sun to some partial shade
- Size: 25 to 35 inches
- Range: 25 to 35 feet

- Tall, full bunches of eight to ten-inch bright red blooms emerge in May
- Round, spiky, and deadly fruit, typically one and a half inches in size
6. Cornus Kousa Chinese Flowering Dogwood
As the tree starts to leaf out in early spring, spectacular flowerheads bloom and persist into early summer. Pink eventually replaces the white of the petals. The magnificent branching type has brilliant golden leaves with vivid red berries in the fall. The fruit, which resembles a raspberry in size and color, puts on a spectacle.
This floral ornamental is attractive to both birds and butterflies. It does not survive drought well, so water it during dry spells. It will thrive well on ordinary, well-drained soil that has medium moisture. It will be up to 25 feet broad and 18 to 25 feet high.
This plant demonstrates strong cold hardiness. In regions of the Midwest, Cornus kousa will perform better and be more disease-resistant than Cornus florida.
- Zones: 4-8
- Part to Full Sun
- Height: 18 to 25 feet
- Span: 25 feet
7. Crabapple Trees
There are numerous types and variations of crab apple plants available. Most springtime flower displays are magnificent, especially on the bigger trees. You can get a crab tree for every location; sizes range from 15 to 25 feet, with circular, oval, or drooping shapes. Look for disease-resistant foliage.
‘Prairie Fire’ (circular 15-20′, abundant pink-red flowers in May, purplish leaves, and deep red bark resembling cherry trees’ bark) is one of the best cultivars for zone four. It develops into a dense, spherical form and is resistant to illness.
“Sparkler” is a wide-spreading tree that can grow up to 25 feet wide and 15 feet high. It can withstand moist circumstances, but it thrives in well-drained soil. It blooms in a vivid rose red in the middle to late spring.
“Indian Summer,” which may reach heights of 12 to 14 feet, is remarkably disease-resistant and adaptable to various soils. In April, rose-red blossoms occur.
“Donald Wyman” (upright and 20′ round) produces white flowers in the spring and a striking red fruit that doesn’t drop and creates a mess in the fall with high resistance to illness.
“Adams,” which is thickly rounded and 20 to 24 feet high by 18 to 20 feet broad. In May, pink blooms replace the redbuds, and the leaves turn orange-red in the fall.
The “Louisa Weeping Crab” gently weeps while sporting pink blossoms. Numerous more! Visit the garden centers to check them out all.
- Zones: 4-8
- Thrives in bright sun
- Dislikes moist soils; thus, well-drained loamy soil is necessary; clay should be avoided.
