11 Evergreen Shrubs With Non Invasive Roots

11 Evergreen Shrubs 

Below is a broad selection of shrubs with a non-aggressive root system:

1. Arborvitae (Thuja)

This genus includes different species: eastern arborvitae (Thuja occidentalis) and western red cedar (Thuja plicata), to name a few. Both are lush and dense. 

If you want to form a hedge or fence, allot 3 to 4 feet interval between these shrubs. Similarly, you can shape them into spherical, tapered, or pendulous. 

The fast-growing arborvitae requires less fertilizer and infrequent pruning, making them low-maintaining. However, get rid of the snow before build-up when winter comes.

• Height and Spread: 3 to 70 feet tall and 25 feet wide
• Soil Condition: Well-draining, moist
• Light Exposure: Full sun
• USDA Hardiness Zones: 2 to 8

2. California Bay Laurel (Umbellularia californica)

Whether rounded or upright, this shrub has yellow-green clustered flowers throughout the year or during spring. Unlike the Mediterranean bay laurel, it is endemic to Southern Oregon. Its leaves have a sharper flavor than the former. 

The high-quality laurelwood is ideal for cabinetry and paneling, whereas the aromatic bay leaves are convenient for cooking and reducing head lice and wood rats. Despite its benefits, it is prone to heart rot. 

3. False Cypress (Chamaecyparis)

Another dense pyramidal shrub is the false cypress, a conifer related to cypresses. Although it has discreet fruits and flowers, it is an ideal pest-resistant and ornamental plant.

Similarly, out of the six species, the lawsonia, obtusa, pisifera, and thyoides bring an excellent view to your house regardless if they are bonsai or dwarf versions.

Nonetheless, it serves as an essential timber in North America. Manufacturers widely use its hardwood for fences, furniture, and boats.

• Height and Spread: 25 to 35 feet tall and 20 to 30 feet wide
• Soil Condition: Acidic, clay or loam
• Light Exposure: Part shade or sun
• USDA Hardiness Zones: 5 to 8

4. Florida Hobblebush (Agarista populifolia)

Hobblebush has arching multi-stems and fragrant white blossoms from spring until summer. Likewise, it is a versatile plant for streams, borders, and slopes. It can also resist seasonal downpours and disease and deer problems.

One of its features attracts animals such as birds, bees, and butterflies. However, its reddish-green leaves are hazardous when you eat them.

• Height and Spread: 8 to 12 feet tall and 5 to 6 feet wide
• Soil Condition: acidic, moist
• Light Exposure: part or full shade
• USDA Hardiness Zones: 7 to 9

5. Mugo Pine (Pinus mugo)

Although it is widely prevalent in the European mountains, plant enthusiasts usually cultivate the dwarf mugo. Aside from the needle-like leaves, this conifer also forms light-colored shoots at its apex.

Despite its slow growth, it withstands drought and winter burn. As a result, it functions as pinecone syrup, animal shelters, windbreaks, erosion control systems, and foundation landscaping. Meanwhile, it produces the oil of turpentine. 

• Height and Spread: 20 feet tall and 25 feet wide
• Soil Condition: Alkaline or acidic, sandy or loamy
• Light Exposure: Direct sun and part shade
• USDA Hardiness Zones: 2 to 7

6. Oregon Grape (Berberis aquifolium)

The Oregon grape is Oregon's state flower. If you want a shrub that requires minimum care, propagate it using cuttings or seeds. It will need mulch and fertilizer occasionally.

It produces a cluster of yellow blooms during late spring. Thus, it creates a focal point in containers, screens, or borders. Despite its name, its blue-black fruits are edible berries, not grapes. 

• Height and Spread: 3 to 10 feet tall and 2 to 5 feet wide
• Soil Condition: fertile, moist, neutral, or alkaline
• Light Exposure: full and part shade
• USDA Hardiness Zones: 5 to 9

7. Red Tip Photinia (Photinia x fraseri)

Photinia is best to cultivate in fall or spring. Likewise, pruning it every year promotes better airflow. It has red-green oval leaves as it matures. Meanwhile, it has bundles of white flowers towards the end of March. 

However, it is susceptible to spots and holes because of excess water. Nonetheless, it remains a disease-free shrub in arid places like Texas and California.

• Height and Spread: 10 to 15 feet
• Soil Condition: neutral, loamy, moist
• Light Exposure: partial sun
• USDA Hardiness Zones: 7  to 9

8. Sasanqua camellia (Camellia sasanqua)

Even though camellia types are native to Japan and China, missionaries introduced them to other continents. Compared to the Japanese camellia, sasanqua has a steady growth. Moreover, you can opt for the hybrid of the two to enjoy their strengths.

As an accent to your landscape, the lovely white and pink blossoms have a pleasant smell from fall to winter. Meantime, the leaves are helpful for cooking and cosmetics.

• Height and Spread: 6 to 10 feet high and 5 to 7 feet thick
• Soil Condition: well-draining, rich, acidic
• Light Exposure: part shade or sun
• USDA Hardiness Zone: 7

9. Skyrocket Juniper (Juniperus scopulorum)

With blue-green foliage, this species is the most slender juniper. The spacing between the conifers must be at least 2 and 1/2 feet to propagate in a row. Then, apply mulch and fertilizer intermittently for optimal development. Similarly, you can plant bamboo alongside the narrow juniper.

• Height and Spread: 15 feet high and 3 to 4 feet thick
• Soil Condition: slightly acidic, moderately moist
• Light Exposure: full sun and part shade
• USDA Hardiness Zone: 4 to 9

10. Southern Wax Myrtle (Myrica cerifera)

Among the quick-growing shrubs on the list, wax myrtle or bayberry has a low-key green flowering. Although it is stable and disease-resistant, people can easily break its branches. In addition to the ornamental purpose, it comes in handy in candle-making and alternative medicine.

• Height and Spread: 15 to 25 feet high and 20 to 25 feet thick
• Soil Condition: flexible
• Light Exposure: any
• USDA Hardiness Zones: 7 to 10

11. Yellow Anise (Illicium parviflorum)

Also known as small or Ocala anise, it is a prominent plant in Florida. Raise anise as a hedge, or espalier with 36 to 60 inches spacing. Moreover, it resists infection and dryness. Its yellow-green flowers bloom in summer.

• Height and Spread: 15 to 20 feet high and 10 to 15 feet thick
• Soil Condition: clay or loam, acidic to neutral
• Light Exposure: part shade or sun 
• USDA Hardiness Zones: 7 to 10

What Is A Non-invasive Root?

Experts recommend plants with non-invasive root systems compared to invasive ones. This is mainly because of the problematic experiences with the latter.

Hence, choose a shrub with non-invasive or shallow roots as much as possible. It will free you from the burdens of protruding roots. They are less likely to spread and damage pavements, gutters, your home or neighbors' property. 

Nonetheless, if non-invasive plants are unsuitable for the USDA zone or physical condition of the yard, they will try to conform to their situation. However, they will eventually grow aggressively because of the nutrient deficiency. For instance, a certain shrub cannot thrive without water for longer periods.
