Everyone wants fast-growing evergreen shrubs for their capacity to rapidly establish themselves as towering private wall or landscape hedge.
There are a lot of species to choose from, but some are more suited to certain environments than others. To help you choose the best evergreen
for your environment, we’ve compiled a list of the 18 fastest-growing species.
1. Arborvitae, Green Giant
The evergreen shrub Green Giant Arborvitae is one of the quickest-growing options. This gigantic hybrid has the potential to reach a height
of 40-50 feet and a spread of 8-12 feet at maturity. They seem like fast-growing evergreen trees while being formed like shrubs. The usual
‘Green Giant’ uses include screening, hedging, and accent plantings. Unless you have the time and energy to shear this type many times a
year, you should only plant it in an area with room to grow to a height of 30 feet or more. Choose ‘Emerald Green’ (described more in this
article) for a low-maintenance option in a more compact area. Planting an arborvitae where its leaves will get at least six hours of sunshine
each day will promote the fastest growth. They may also grow in partial shade; however, their development will be slowed somewhat.
You may find out on this map if you don’t know what USDA Plant Hardiness Zone you live in. Green Giant Arborvitaes thrive in Zones
5-8. This plant is ideal if you reside in a region that experiences severe winters due to its ability to withstand snow and wind.
2. Cypress Leyland
Fast-growing and low-maintenance Leyland Cypress (Cupressus leylandii) hedges and privacy screens are staples in many landscapes.
This vigorous hybrid starts looking like a shrub, yet it may eventually tower above most ornamental trees. Leyland cypress trees typically
increase in height by 3 to 4 feet every year, ultimately maturing to a height of 60 to 70 feet and a width of 15 to 20 feet.
The rapid growth of Leyland Cypress trees makes them ideal for use as a tall hedge or perimeter plant on expansive landscapes. This tree
is great for screening off sights and sounds because of its fast growth rate and mature height. This plant type may be readily sculpted into
a groomed appearance by shearing.
This plant does best in full sun but may survive in dappled light if necessary; however, its growth pace will be affected. These trees are not
the greatest option in windy regions or climates where ice forms on the branches (if a huge shrub is needed, go for Green Giant Arborvitae
instead due to its superior strength).
3. The Spartan Juniper
Commonly known as “Spartan Juniper,” the Juniperus chinensis ‘Spartan’ is a popular evergreen conifer. They may not be the quickest
growers in the neighbourhood, but their 12–18 inches annual growth rate is rather good. At maturity, these plants may measure 15–18 feet
in height and 4–5 feet in width.
These quick-growers are often used as medium-height hedges, foundation plants, or privacy screens. The thick foliage offers privacy all
year and can resist severe shearing if necessary. When looking for an evergreen, junipers are one of the best options since they are resistant
to deer. Spartan Junipers thrive in full sun but may also survive in dappled light. Do not place them in areas of constant shadow. Keep
them well-watered for the first year or two after planting, and include organic matter into the soil before planting for optimal development.
4. Prague Viburnum
As its name suggests, Prague Viburnum (Viburnum x pretence) is a hybrid of two types of Viburnums. When fully mature, these bushes
grow between 8 and 10 feet tall and 6 and 8 feet broad. Prague viburnums have a high growth rate, expanding by roughly 2 feet yearly. You
may use this plant as a windbreak, a screen, or a hedge. It also functions very well as an ornamental plant. The attractive evergreen shrub
retains its glossy, dark green foliage through even the coldest Midwestern winters. Beautiful pink springtime buds open to reveal delicately
scented, pure white blossoms. Viburnum is like full sun but may still thrive in dappled light. The ideal climate for a Prague Viburnum is Zones
5. Moonlight Juniper
The tall evergreen shrub Juniper (Juniperus scopulorum ‘Moonglow’) has beautiful silvery green leaves. These well-liked plants grow to a height
of 18-20 feet and a width of 6-8 feet in their mature form, a growth rate of roughly 2 feet each year. ‘Moonglow’ is often used as a tall privacy
screen or hedge plant. Naturally pyramidal in shape, these plants need little care (unless clipped frequently into a formal hedge). Songbirds
love juniper trees, so seeing them planted in groups in wildlife gardens is not surprising. Moonglow Juniper is shade-intolerant and thrives in
bright sunlight. This plant, however, can survive low temperatures and thrive in USDA Plant Hardiness Zones 3-7.
6. Arborvitae, Color of Emerald
Evergreen conifer Thuja occidentalis ‘Emerald Green’ has thick, beautiful green leaves. This common landscaper may add a foot or two to its
yearly height in ideal circumstances. At maturity, this type of Arborvitae grows to be between 10 and 15 feet tall and 3 to 4 feet broad.
Because it grows so densely, ‘Emerald Green’ is often used as a hedge. They are ideal for privacy screens in urban areas because of their mature
height of slightly over 10 feet. These bushes are hardly enough to spend years in containers if necessary and look great when used as topiary.
Emerald Green Arborvitae develops at an accelerated rate when exposed to full sun (at least six hours of sunshine each day). When exposed to
varying degrees of shade, plant specimens slow their growth. Adequate soil moisture is also necessary for optimal development. The hardiness
zone range for Emerald Green Arborvitae is from 4 to 8.
7. Boxwood, Sprinter
One of the quickest-developing boxwood species, ‘Sprinter Boxwood’ (Buxus microphylla ‘Bulthouse’), is popular. In only a few short years,
these fast-developing plants will have reached their full height and width of 2–4 feet. The growth rate is variable, from roughly 4 inches per
year in bad circumstances to 10-12 inches per year in perfect conditions.
Common applications for this boxwood variety include usage as a hedge, border, or accent plant. You may maintain the bushes in their
original state or shear them into a neat linear shape. Although it thrives in full sun, Sprinter Velvet Boxwood may survive in dappled light.
It’s hardy in warm climates (Zones 4-8).
8. Hicks Yew
You may use the Hicks Yew (Taxus x media ‘Hicksii’) shrub with dark green needles to create a hedge or a screen. Although they develop
more slowly than Arborvitae or Juniper, these shrubs may gain 6-10 inches in a year under ideal circumstances. Hicks Yew trees may grow
up to 10–15 feet tall and 3–6 feet broad when fully mature.
Most often, ‘Hicks’ is planted as a barrier. Yew is largely self-healing because it can fill in thick foliage on bare limbs. They may be more
suitable for the long run than Arborvitae, even though they don’t reach their full height as quickly. It is possible to shear these plants into
topiary forms as well. The ideal solar exposure for Hicks Yew ranges from full sun to light shade. Its hardiness zone range is 4-8.
9. Nellie Stevens Holly
The thick, glossy green leaves of the hybrid holly known as Nellie Stevens Holly (Ilex x ‘Nellie Stevens’) are a major selling point for this
variety. Nellie Stevens Holly has the potential to expand by two to three feet a year, ultimately reaching a height of 15 to 25 feet and a spread
of 8 to 15 feet. This holly is often planted as a hedge for seclusion or as staggered plants along a fence or path. It has much potential as a garden
feature since it may be sheared into a formal hedge or left unpruned for a more natural effect. Ms Nellie Stevens Holly thrives in bright sunlight
but may survive in dappled light. Zones 6–9 are ideal for these shrubs.
10. Cherry Laurel
The tall broadleaf evergreen shrubs known as cherry laurels (Prunus Lauro Cerasus) are admired for their glossy dark green foliage and
brilliant white blossoms. These fast-growing blooming evergreens may reach a height of 10-12 feet and a spread of 8-10 feet in their mature
form. A fast-growing, descending hedge or evergreen living fence, cherry laurel bushes are a popular choice. Cherry Laurels provide
excellent screening all through the seasons. You may also use a single plant as a standalone shrub or specimen. Pollinators are drawn to the
blooms, and as they mature, the blossoms turn into tiny, dark fruits that the birds eat. These bushes thrive in direct sunlight but may also survive in
dappled light. Also, laurel may tolerate somewhat saline soil conditions.
