What Is Coppertop® Sweet Viburnum?
Before we dive into the “how-to,” let’s look at the “what.” Understanding the botanical pedigree of a plant helps us predict how it will behave in your backyard.
Botanical Background
Coppertop® is a specialized cultivar of Viburnum odoratissimum, commonly known as Sweet Viburnum. While the parent species is known for its large, leathery leaves and rapid growth, the ‘BRANT01’ cultivar (marketed under the Coppertop® brand) was selected specifically for its unique foliar transitions and more manageable growth habit.
The Evergreen Habit
Unlike deciduous viburnums that drop their leaves in the fall, Coppertop® is a true evergreen. It maintains a dense canopy of foliage 365 days a year, providing essential “bones” to the garden during the bleak winter months.
Size and Stature
At maturity, this shrub typically reaches 8 to 10 feet in height and spans about 5 to 6 feet in width. This upright, vase-like to oval habit makes it large enough to function as a formidable screen but compact enough not to swallow your entire foundation planting.
The Signature Look
The most striking feature of this plant is the new growth. In early spring, the tips of the branches erupt in shades of copper-red and deep maroon. As these leaves mature, they transition into a high-gloss, dark emerald green. This creates a multi-toned, layered effect that looks like a sunset resting on a deep green sea.
Fragrant Blooms
Adding to its sensory appeal, Coppertop® produces clusters of small, white, star-shaped flowers in late spring. They carry a light, pleasant fragrance that wafts through the garden, signaling the true start of the warm season.

Why Gardeners Love This Evergreen Viburnum
In the world of landscape design, we look for plants that solve problems. Coppertop® is a problem-solver. Here is why it earns a spot in almost every plant palette I design for warmer climates.
1. Brilliant Copper-Colored New Growth
In a sea of green, the copper-red flush of this viburnum provides a focal point that rivals flowering shrubs. Because the plant pushes new growth multiple times a year (especially after a light pruning), you can enjoy this color transition from spring through autumn.
2. Year-Round Evergreen Privacy
Most people want privacy now. Because this evergreen viburnum is a vigorous grower, it fills in gaps quickly. The thick, leathery leaves overlap to create a visual and acoustic barrier, muffling street noise and blocking the view of neighbors.
3. Exceptional Heat Tolerance
Many evergreens struggle when the thermometer hits 90°F and stays there. Coppertop® thrives in the humidity of the Southeast and the dry heat of the West. It doesn’t “melt” or wilt under intense afternoon sun, provided it has been properly established.
4. Natural Deer Resistance
While no plant is 100% “deer-proof” (a starving deer will eat almost anything), the thick, slightly fuzzy, and leathery texture of Viburnum odoratissimum leaves is generally unappealing to deer. They tend to bypass this shrub in favor of more tender hostas or roses.
5. Drought Tolerance
Once the root system has moved deep into the soil (usually after the first two growing seasons), Coppertop® is remarkably drought-tolerant. It can handle periods of dry weather without the foliage drooping or browning at the edges.
6. Low-Maintenance Care
This isn’t a plant that requires constant “fussing.” It doesn’t need deadheading, and its natural shape is quite attractive, meaning you only need to pull out the shears if you want to maintain a specific height or a formal hedge shape.
Best Growing Conditions for Success
To get the most out of your evergreen viburnum, you need to put the right plant in the right place.
USDA Hardiness Zones
Coppertop® is a warm-weather favorite, rated for Zones 7b through 10b. In Zone 7b, it may experience some leaf bronzing or minor tip burn during exceptionally harsh winters, but it typically bounces back with vigor in the spring.
Sun Exposure
For the best copper color, full sun (at least 6 hours of direct light) is ideal. However, it is highly adaptable and will grow beautifully in partial shade. Note that in deep shade, the growth will be more leggy, and the copper color of the new leaves will be less intense.
Soil Preferences
One of the best traits of this viburnum is its soil adaptability. It can handle:
- Clay Soils: As long as the area doesn’t stay swampy.
- Loam: The “gold standard” for any plant.
- Sandy Soils: It will need more frequent watering and mulching in sandy conditions.
Drainage
If there is one thing this plant hates, it’s “wet feet.” Ensure the planting site drains well. If you have heavy clay that holds water like a bathtub, consider planting in a slightly raised mound.
How to Plant Coppertop® Sweet Viburnum: A Step-by-Step Guide
Proper planting is the difference between a shrub that survives and a shrub that thrives. Follow these steps for professional-grade results.
1. Timing
The best time to plant is in the spring or fall. This allows the root system to establish itself without the stress of extreme summer heat or winter freezes.
2. Choosing the Location
Measure your space. Remember that this shrub will eventually be 5-6 feet wide. If you are planting it near a fence or wall, leave at least 3 feet of space between the center of the plant and the structure to allow for airflow and maintenance access.
3. Preparing the Hole
Dig a hole that is twice as wide as the root ball but no deeper. You want the top of the root ball to sit slightly above the surrounding soil level (about half an inch) to allow for settling and to ensure oxygen reaches the upper roots.
4. Soil Amendment
If your soil is very poor, mix in some organic compost with the native soil you removed from the hole. Avoid using 100% potting soil in the hole, as this can create a “container effect” where roots refuse to move into the tougher native soil.
5. Planting
Gently remove the viburnum from its nursery container. If the roots are circling the pot (root-bound), use your fingers or a clean knife to lightly score the sides and bottom. Place the plant in the hole, backfill with soil, and tamp down gently with your hands to remove air pockets.
6. Spacing for Hedges
If you are creating a “living wall” or privacy hedge, space your Coppertop® viburnums 4 to 5 feet apart (measured from the center of one plant to the center of the next). This ensures the branches will overlap within 2-3 years to form a solid screen.
Comprehensive Care Guide
Once your Coppertop® is in the ground, maintenance is straightforward.
Watering Requirements
- First Season: Water deeply 2-3 times a week, depending on rainfall. The goal is to keep the root ball moist but not saturated.
- Established Plants: Once the plant is established (after 1-2 years), it only needs supplemental water during extended dry spells.
Fertilizing
Apply a balanced, slow-release fertilizer (such as a 10-10-10 or a dedicated shrub and tree food) in early spring just as the copper buds begin to swell. This provides the nutrients needed for that big spring push of growth.
Pruning for Color and Shape
Pruning is best done in late spring or early summer, immediately after the white flowers have faded.
- To maintain a hedge: Shear the sides and top to the desired dimensions.
- To encourage color: Lightly tipping the branches (removing the top 2-3 inches) will stimulate the plant to push out a new flush of copper-red foliage.
Mulching
Apply a 2-to-3-inch layer of organic mulch (pine bark, shredded hardwood, or pine straw) around the base of the plant. Keep the mulch a few inches away from the trunk itself to prevent rot. Mulch regulates soil temperature and retains moisture.
Landscaping Ideas: Where to Use Coppertop®
Because of its versatility, this evergreen viburnum fits into various garden styles, from formal English gardens to modern minimalist landscapes.
- The “Instant” Privacy Hedge: Use it along property lines where you need a screen that looks better than a wooden fence.
- Foundation Planting: Plant it at the corners of your home to soften the architecture and provide year-round structure.
- Specimen Plant: With its unique copper tips, it can stand alone as a focal point in a small garden bed.
- The Backyard “Screen”: Use it to hide unsightly elements like AC units, trash cans, or pool equipment.
- Mixed Shrub Border: Pair it with contrasting textures, such as the fine needles of a ‘Blue Pacific’ Juniper or the large, silver leaves of a ‘Silver Falls’ Dichondra (as a groundcover).
Common Problems and How to Solve Them
While Coppertop® is resilient, no plant is entirely immune to issues. Here is what to look for:
Root Rot
- Symptoms: Yellowing leaves, wilting despite wet soil, and a general decline in health.
- Cause: Poor drainage or overwatering.
- Solution: Improve drainage or move the plant to a higher spot. Ensure you aren’t watering daily once established.
Scale Insects
- Symptoms: Small, bumpy protrusions on the stems and underside of leaves; sticky “honeydew” residue.
- Solution: Treat with horticultural oil or Neem oil during the dormant season or early spring.
Aphids
- Symptoms: Curled or distorted new growth (the copper tips).
- Solution: Often, a strong blast of water from the hose will dislodge them. If the infestation is heavy, use insecticidal soap.
Leaf Spot
- Symptoms: Small brown or black spots on the leaves, usually during very wet, humid summers.
- Solution: Improve airflow by thinning out some interior branches. Avoid overhead watering (use a soaker hose or aim at the base).

Frequently Asked Questions (FAQ)
How fast does Coppertop® Sweet Viburnum grow?
In ideal conditions (full sun and regular water), you can expect 12 to 24 inches of growth per year until it reaches maturity.
Is it truly deer resistant?
Yes. While no plant is 100% deer-proof, this viburnum is categorized as “highly resistant.” Deer generally dislike the texture and taste of the leathery leaves.
Does it need full sun?
It performs best and shows the most copper color in full sun, but it is quite happy in partial shade.
Is it drought tolerant?
Yes, but only after it is established. For the first year, you must treat it like a “thirsty” plant. By year three, it can handle significant dry spells.
When should it be pruned?
Prune after the spring flowering cycle. This ensures you don’t cut off the flower buds and allows the plant time to grow new copper foliage before winter.
How large does it become?
Expect a mature size of 8-10 feet tall and 5-6 feet wide. You can keep it smaller (around 5-6 feet tall) with annual pruning.
Can it be grown as a hedge?
Absolutely. It is one of the best choices for a medium-to-large evergreen hedge due to its density and upright growth.
Does it attract pollinators?
Yes! The fragrant white flowers in late spring are a favorite for bees, butterflies, and other beneficial pollinators.
Expert Growing Tips for the Best Results
As a pro, I always share these “insider” tips with my clients to ensure their plants look like they belong in a magazine:
- The “Airflow” Rule: When planting a hedge, don’t jam the plants directly against a solid wooden fence. Leave a 2-3 foot gap to allow air to circulate behind the plants; this prevents fungal leaf spot.
- Finger Test for Water: Don’t water on a schedule. Stick your finger 2 inches into the soil. If it feels dry, water. If it’s muddy, wait.
- Encourage Flush: If you want a fresh burst of copper color for a summer garden party, give the plant a very light “haircut” (trimming just the tips) 3-4 weeks before the event.
- Spring Feeding: Always fertilize before the first big growth spurt. If you wait until the leaves are already out, you’ve missed the peak window.
- Watch the pH: While adaptable, these viburnums prefer slightly acidic to neutral soil (pH 5.5 to 7.0). If your leaves look yellow but the veins are green (chlorosis), check your soil pH.
- Don’t Over-Prune the Bottom: When trimming a hedge, always keep the bottom slightly wider than the top. This allows sunlight to reach the lower branches so the hedge stays thick all the way to the ground.
- Mulch Maintenance: Refresh your mulch every spring. This not only looks good but replenishes the organic matter as the old mulch breaks down into the soil.
- Winter Hydration: In Zone 7b, if a hard freeze is predicted, give your viburnum a deep watering the day before. Moist soil stays warmer than dry soil and helps prevent “winter burn.”
