The generator kicks on as rain taps the patio roof, and its hard plastic housing becomes the first thing visitors see. You step around the side yard, hoping greenery can soften the view while keeping the equipment reachable.
This guide to the Best Shrubs to Hide Generator compares practical options for that awkward corner. Read on for a clear shortlist.
Key Takeaways
- Measure the generator’s height and width first, then choose a mature plant size that screens it without crowding the service area.
- Prioritize mature width and growth habit, since a narrow upright shrub fits tighter spaces than a spreading hedge.
- Check your climate zone, sunlight, and winter lows against the listed hardiness range before ordering live plants.
- Preserve required clearance for ventilation, refueling, controls, and maintenance, and never let foliage touch hot equipment.
- Compare the pack count and starting size with your planned hedge length, because smaller plants may need more time to create coverage.

Proven Winners Neatball Boxwood, 1-Gallon
If you want the generator screened by a tidy, formal shrub rather than a towering tree, this Neatball boxwood is a sensible starting point. Its rounded habit and 1-gallon size fit a border or staged planting.
Boxwood keeps its evergreen foliage through the seasons, providing year-round structure. The limitation is scale: one 1-gallon shrub offers a foundation, not immediate generator coverage.
- Brand:Proven Winners
- Plant Type:Neatball boxwood shrub
- Plant Size:1 gallon
- Foliage:Evergreen
- Additional Feature:Formal rounded shape
- Additional Feature:Proven Winners cultivar
- Additional Feature:Border-friendly planting
-
Highlander Boxwood, Six 3.5-Inch Cubes
For a straight, orderly screen, this six-plant pack is a practical starting point. The upright growth, evergreen foliage, and multi-plant format suit a narrow hedge around a generator.
Each plant arrives in a 3.5-inch cube, so expect a young hedge rather than instant coverage. You will need consistent spacing and time for these small plants to fill the screen.
- Plant Type:Highlander boxwood
- Plant Size:3.5-inch cubes
- Plant Count:6
- Growth Rate:Fast-growing
- Foliage:Evergreen
- Additional Feature:Buxus sempervirens cultivar
- Additional Feature:Privacy hedge planting
- Additional Feature:Border and screen use
-
Perfect Plants Sunshine Ligustrum, 1-Gallon
If your generator area needs a little color, Sunshine Ligustrum brings yellow foliage instead of the usual green wall. It suits zones 6-10, and its 1-gallon size works well for starting a hedge or border in stages.
The listing also identifies it as non-invasive and hardy to -10°F, useful details for year-round planting plans. Its limitation is visual rather than functional: the bright foliage draws attention, and a 1-gallon plant will not hide a generator immediately.
- Brand:Perfect Plants
- Plant Type:Sunshine ligustrum
- Plant Size:1 gallon
- Foliage:Golden yellow evergreen
- Additional Feature:Zones 6-10
- Additional Feature:Listed as non-invasive
- Additional Feature:Hedge and border use
-
Carolina Cherry Laurel, Two 4-6-Inch Plants
Carolina cherry laurel makes sense for a small screening project where you want two live plants to begin the row. The species suits privacy hedges, and the paired 3-inch pots simplify a two-location planting.
These are only 4-6 inches tall, so they are seedlings rather than instant barriers. Initial coverage will be limited, but the two-pack gives you a clear starting point for a future evergreen screen.
- Plant Type:Carolina cherry laurel
- Plant Size:4-6 inches tall
- Plant Count:2
- Foliage:Evergreen
- Additional Feature:Prunus caroliniana species
- Additional Feature:Three-inch nursery pots
- Additional Feature:Privacy screen planting
-
Waxleaf Privet, 15-Plant Hedge
If you are covering a longer stretch rather than a single corner, this 15-plant pack gives you useful planting volume. Its evergreen foliage and dedicated privacy hedge purpose make it a logical choice for a broad generator surround.
The tradeoff is uncertainty: the listing does not give plant size, so initial coverage and spacing are harder to forecast. Privet can also be restricted in some regions, so check local guidance before planting.
- Plant Type:Waxleaf privet
- Plant Count:15
- Foliage:Evergreen
- Additional Feature:Live plant collection
- Additional Feature:Privacy hedge planting
- Additional Feature:High-volume pack
-
Proven Winners Sprinter Boxwood, 2-Gallon
Sprinter is worth considering if you want a more established starting plant than a small nursery cube. Its 2-gallon size, evergreen foliage, and tidy hedge role fit formal beds around a generator.
The faster-growing boxwood habit can help shorten the wait for a filled-in screen. Still, one shrub will not create full coverage by itself, so plan a row and give each plant room to mature.
- Brand:Proven Winners
- Plant Type:Sprinter boxwood
- Plant Size:2 gallons
- Growth Rate:Fast-growing
- Foliage:Evergreen
- Additional Feature:Proven Winners cultivar
- Additional Feature:Formal hedge use
- Additional Feature:Evergreen boxwood foliage
-
Perfect Plants Thuja Green Giant, 3-Gallon
Choose this arborvitae when the generator sits beside a larger yard or property line and you need rapid vertical coverage. The 3-gallon size combines dense evergreen foliage with a listed growth rate of 3-5 feet per year, giving you a strong long-term screen.
That speed is also the main constraint: Green Giants need thoughtful spacing and can overwhelm a narrow bed as they mature. Full sun is specified, so a shaded installation may not match the plant's intended conditions.
- Brand:Perfect Plants
- Plant Type:Thuja Green Giant arborvitae
- Plant Size:3 gallons
- Growth Rate:3-5 feet yearly
- Foliage:Dense evergreen
- Additional Feature:Full-sun placement
- Additional Feature:Privacy screen use
- Additional Feature:Natural fence option
-
Brighter Blooms Thuja Green Giant, 2-3-Foot
Brighter Blooms targets buyers who want a taller starting plant than a small liner. At 2-3 feet, this Thuja Green Giant can create earlier visual structure, while its evergreen foliage keeps the screen useful year-round.
Your main limitation is logistics: this listing cannot ship to AK, AZ, HI, or OR. It is also a sizable planting choice, so leave room for mature growth rather than crowding it against the generator or property line.
- Brand:Brighter Blooms
- Plant Type:Thuja Green Giant arborvitae
- Plant Size:2-3 feet
- Foliage:Evergreen
- Additional Feature:Oversize arborvitae
- Additional Feature:Shipping exclusions listed
- Additional Feature:Privacy tree use
-
Green Giant Arborvitae, 10-Pack
If you are planting a long run, this 10-pack keeps the project focused on uniform starter trees. Each arrives at 7-10 inches tall, and the Green Giant cultivar brings an evergreen screen concept suited to rows and boundaries.
These are much smaller than the established arborvitae in this roundup, so they will offer little immediate concealment. The upside is planting flexibility, but you must plan spacing, watering, and patience across ten locations.
- Plant Type:Thuja Green Giant arborvitae
- Plant Size:7-10 inches tall
- Plant Count:10
- Foliage:Evergreen
- Additional Feature:Long-row planting
- Additional Feature:Starter tree format
- Additional Feature:Privacy screen use
-
Golden Euonymus, Three 2.5-Inch Cubes
For a generator beside a low wall or garden bed, Golden Euonymus adds variegated yellow-green foliage while keeping the planting evergreen. The three-pack and 2.5-inch cubes suit a small border plan where you want color as well as concealment.
Do not expect immediate screening from these small nursery cubes; they are better for a gradual hedge than a quick visual block. The bright variegation may also draw more attention than a plain green shrub, which can be either a design asset or a mismatch.
- Plant Type:Golden euonymus
- Plant Size:2.5-inch cubes
- Plant Count:3
- Foliage:Evergreen, variegated
- Additional Feature:Aureo-Marginatus variety
- Additional Feature:Easy-care evergreen
- Additional Feature:Hedge and shrub use
Frequently Asked Questions
How far should shrubs be from a generator?
Use the clearance distances in your generator manual as the minimum, and follow stricter local fire or building requirements if they apply. The correct distance can change based on the unit, exhaust location, walls, windows, and fuel source. Measure to the plant’s mature spread, not just the trunk or container edge. Keep the required zone clear of branches, mulch, dry leaves, and other combustible materials.
What shrubs are best for hiding a generator?
Good choices are usually evergreen, climate-appropriate shrubs with manageable roots and predictable mature sizes. Depending on your region, options can include inkberry holly, yaupon holly, boxwood, wax myrtle, or podocarpus. Choose plants that tolerate the site’s sun, soil, and winter conditions. The best shrub is not simply the densest one, it is the one that provides privacy while staying outside the generator’s safety and service area.
Can I surround the generator with a hedge?
Avoid an enclosed hedge around the unit. A solid ring of plants can restrict airflow, trap exhaust heat, block service access, and increase fire risk. Use a staggered screen on one or more sides, positioned beyond the required clearance. Keep exhaust outlets, vents, control panels, and the technician’s working area fully open.
Can shrubs be taller than the generator?
They can be taller if they are planted beyond the required clearance and do not interfere with exhaust, airflow, overhead requirements, or service access. Height alone is not the problem, placement is. Avoid allowing branches to grow over the enclosure or beneath eaves. Prune the plants before they reach the generator, rather than waiting until they obstruct a vent or panel.
How do I maintain shrubs planted near a generator?
Inspect the area several times a year for overgrown branches, leaves, mulch, weeds, and irrigation problems. Trim plants before they enter the clearance zone, and remove dry debris promptly. Keep a clear path to the generator for maintenance and emergency shutoff. During scheduled servicing, ask the technician to confirm that the shrubs still provide adequate airflow and access.
