The best plants around a deck combine dense foliage at eye level with layered heights and seasonal color, giving you both a living screen and a garden worth looking at. A mix of evergreen shrubs for year-round privacy, ornamental grasses for texture, flowering perennials for color, and climbers for vertical coverage will transform a bare deck surround into something that feels enclosed and inviting without the claustrophobic effect of a solid fence. The specific plants that work depend on your climate zone, sun exposure, and how quickly you need results, but a few categories consistently deliver.
Evergreen Shrubs for Year-Round Screening
Privacy is the top reason people plant around a deck, and evergreen shrubs are the backbone of any screening plan. Deciduous plants look great from spring through fall, but they leave you exposed in winter when the leaves drop. Evergreens hold their foliage all year, which means the privacy they provide in July is still there in January.
For a dense, formal hedge along a deck’s edge, cherry laurel (Prunus laurocerasus) and bay laurel (Laurus nobilis) are solid performers in mild to moderate climates. Both produce thick walls of glossy green foliage and tolerate regular pruning well. Research on hedges made from these two species found that when grown densely enough, they can also measurably reduce noise from nearby roads, which is a useful side benefit if your deck faces a street.1Journal of Agricultural Engineering. Noise attenuation provided by hedges The key factor was hedge porosity: the denser the growth, the more sound got absorbed. That finding tracks with common sense, but it means you should plant screening shrubs close enough together that the canopy knits into a continuous wall rather than leaving gaps between individual plants.
Other reliable evergreen options include:
- Arborvitae: Fast-growing columnar forms like ‘Emerald Green’ or ‘Green Giant’ reach screening height within a few years and stay narrow, making them ideal where space is tight beside a deck.
- Boxwood: Slower growing but extremely dense, boxwood works well as a lower hedge (three to four feet) when you want to define the deck’s perimeter without blocking a view entirely.
- Holly: Varieties like ‘Nellie R. Stevens’ or ‘Sky Pencil’ provide year-round screening with glossy leaves and, on female plants, red winter berries.
- Privet: Semi-evergreen to evergreen depending on species and zone, privet grows quickly and tolerates hard pruning, making it forgiving for beginners.
Spacing depends on the species, but a general guideline is to plant screening shrubs at about two-thirds of their mature spread apart. For a six-foot-wide shrub, that means roughly four feet center to center. Planting closer gives faster coverage but creates more root competition down the line.
Ornamental Grasses for Texture and Movement
A wall of green shrubs handles privacy, but it can look flat and monotonous without something to break it up. Ornamental grasses are the easiest way to add movement, height variation, and a completely different texture to the planting around a deck. Their feathery plumes catch the breeze in a way that stiff-leaved shrubs never will, and they create a soft rustling sound that adds to the sense of being in a garden rather than behind a fence.
Maiden grass (Miscanthus sinensis) and its cultivars are among the most popular choices for deck surrounds. They grow four to eight feet tall depending on variety, produce airy seed heads in late summer, and turn golden or copper in fall. ‘Morning Light’ has silver-edged leaves that look especially good against dark wood decking. ‘Gracillimus’ is narrower and more upright, useful for tighter spaces.
For something shorter, blue oat grass (Helictotrichon sempervirens) forms tidy mounds of steel-blue foliage around two feet tall, making a striking border along the deck’s base. Karl Foerster feather reed grass (Calamagrostis × acutiflora ‘Karl Foerster’) is another good mid-height option: very upright, very tidy, and one of the earliest grasses to send up its wheat-colored plumes.
One caution with grasses: some species spread aggressively by underground runners. Miscanthus sinensis is a clumper and stays put, but ribbon grass (Phalaris arundinacea) and some species of Miscanthus from warmer regions can become invasive. Stick to clump-forming varieties and check local invasive species lists before planting.
Climbing Plants for Vertical Coverage
If your deck has posts, railings, a pergola, or an adjacent wall, climbing plants can cover vertical surfaces with foliage and flowers faster than almost any other approach. They turn bare structural elements into living screens, and a single vigorous vine can cover more square footage than a row of shrubs planted in the same footprint.
Climbers attach to surfaces in different ways, and the method matters when you are planting near a deck. Self-clinging species like Boston ivy (Parthenocissus tricuspidata), English ivy (Hedera helix), and trumpet creeper (Campsis radicans) produce adhesive pads or aerial roots that grip directly onto surfaces. Research examining the attachment mechanics of these three species found that each uses a distinct detachment process, with Boston ivy relying on adhesive pads and English ivy and trumpet creeper using root-based systems that anchor into surface irregularities.2PubMed Central. Quantifying the attachment strength of climbing plants: a new approach The practical takeaway is that self-clingers can damage wood siding, mortar joints, and painted surfaces over time. They are better suited to stone walls, concrete, or purpose-built masonry than to the deck structure itself.
For deck railings and pergolas, twining climbers and tendril climbers are safer choices because they wrap around supports rather than gripping onto flat surfaces. Some of the best options include:
- Clematis: Hundreds of varieties offering flowers from early spring through fall, in colors from white to deep purple. Most clematis are well-behaved and easy to train on a trellis or wire system.
- Jasmine: Star jasmine (Trachelospermum jasminoides) is evergreen in warm climates and produces intensely fragrant white flowers in early summer. It twines neatly and grows to about fifteen feet.
- Climbing hydrangea: Slower to establish but stunning once mature, with large white lacecap flowers and peeling bark for winter interest. Uses aerial roots, so best directed onto a trellis rather than directly onto wood.
- Wisteria: Dramatic cascades of purple or white flowers in spring. Extremely vigorous and heavy, so it needs a very sturdy support structure. Not for flimsy pergolas or lightweight trellises.
If you want near-instant coverage for a single season while slower perennial climbers establish themselves, annual vines like morning glory, hyacinth bean, or cup-and-saucer vine (Cobaea scandens) can scramble up a trellis in weeks.
Flowering Perennials and Shrubs for Color
Privacy screening provides the backbone, but it is flowering plants that make the area around a deck feel like a garden rather than a hedge row. The trick is to choose plants with staggered bloom times so something is always in flower from spring through fall.
Hydrangeas are one of the most popular flowering shrubs for deck borders, and for good reason. They bloom for weeks in midsummer, tolerate part shade (common near decks that sit under a tree canopy), and their large flower heads create an immediate visual impact. Panicle hydrangeas (Hydrangea paniculata) are the hardiest and most sun-tolerant. Bigleaf hydrangeas (H. macrophylla) produce the classic blue or pink mophead blooms and prefer afternoon shade.
For spring color, azaleas and rhododendrons deliver masses of blooms in shades from white to deep magenta. Peonies are another spring-to-early-summer standout, with fragrant flowers and foliage that stays attractive all season. Daylilies pick up the color baton in midsummer and are almost impossible to kill, making them a reliable filler for sunny spots. For fall, Japanese anemones and asters keep the show going until frost.
Layering heights matters. Plant taller flowering shrubs like hydrangeas and butterfly bushes behind lower perennials like catmint, salvia, and coreopsis. The depth creates a sense of lushness and conceals bare stems at the base of taller plants, which is particularly useful because the view from a deck is often looking down into the planting bed.
Container Plants for Flexibility
Not every deck has planting beds along its edges. Raised decks, decks over concrete, and decks attached to townhouses or condos often have nowhere to put plants in the ground. Containers solve the problem and add a layer of flexibility that in-ground plantings cannot match: you can rearrange them, swap out seasonal displays, and take them with you when you move.
Large containers (at least 18 inches in diameter) are essential for anything meant to provide screening. A single dwarf arborvitae, a columnar holly, or a tall ornamental grass in a big pot can block a sightline effectively. Grouping three or five pots of varying heights looks more natural than a single uniform row.
Bamboo in containers is one of the fastest ways to create a tall, narrow privacy screen on a deck. Running bamboo, which spreads aggressively in the ground, becomes manageable when confined to a large planter. Clumping bamboo types are even better behaved. Either way, bamboo in a well-sized container can reach eight to twelve feet and produces a rustling, tropical-looking screen that works in both modern and traditional settings.
The main drawback of containers is watering. Potted plants dry out far faster than those in the ground, especially on a sun-baked deck. Self-watering planters, drip irrigation on a timer, or simply grouping pots together (which reduces evaporation) all help. In cold climates, you also need to consider overwinter survival: roots in a pot are much more exposed to freezing than roots in the ground, so choose plants rated at least one hardiness zone colder than your area, or move pots into a garage for winter.
Plants That Help With Mosquitoes
Plenty of gardening blogs claim that certain plants repel mosquitoes just by growing nearby. The reality is more nuanced. Most “mosquito-repelling” plants contain volatile oils that deter insects in concentrated or crushed form, but simply having the plant in the ground does not create a meaningful mosquito-free zone around your deck. You would need to crush the leaves and apply the oils to your skin for the repellent compounds to work as direct personal protection.
That said, there is at least some evidence that certain plants grown in density near living spaces can reduce mosquito presence. A field study in East Africa found that potted lantana placed around house entry points cut indoor mosquito counts by roughly half compared to houses without plants.3PLoS ONE. Repellent Plants Provide Affordable Natural Screening to Prevent Mosquito House Entry in Tropical Rural Settings—Results from a Pilot Efficacy Study The reductions were substantial, with certain mosquito species dropping by over 80% in houses screened with lantana. These were tropical conditions and a particular mosquito species, so the results do not translate directly to a suburban deck in North America. But they do suggest that densely planted aromatic species near outdoor living areas are more than pure folklore.
Lantana, citronella grass (Cymbopogon nardus, the source of citronella oil), lavender, rosemary, and lemon balm are all commonly grown around decks partly for this reason. Even if their ambient mosquito deterrence is modest, they bring fragrance, flowers, and culinary use that justify their space on their own merits. Lavender and rosemary, in particular, thrive in the well-drained, sunny conditions often found along deck edges and look attractive year-round in mild climates.
Pet Safety Around Deck Plantings
If dogs or cats use your deck and yard, the plant list needs a safety check. Actual poisoning from ornamental plants is uncommon in household pets, and veterinary literature notes that the risk is often overestimated in popular advice while simultaneously being underrecognized by clinicians who may not consider plant toxicity in differential diagnosis.4CABI Reviews. Toxic plants and companion animals Still, a few widely used landscape plants contain compounds that can cause serious problems if a pet chews on them.
Plants to avoid or place out of reach when pets have access:
- Sago palm: All parts are toxic to dogs, and ingestion of even a small amount of the seeds can cause liver failure. One of the most dangerous common ornamental plants for pets.
- Lilies (true lilies, Lilium and Hemerocallis): Extremely toxic to cats. Even small exposures, including pollen on fur that is then groomed off, can cause kidney failure. Daylilies are included in this risk for cats, despite being harmless to dogs.
- Oleander: All parts contain cardiac glycosides. Sometimes planted as a fast-growing screen in warm climates but dangerous to dogs, cats, and humans.
- Azaleas and rhododendrons: Contain grayanotoxins that can cause vomiting, cardiac issues, and in rare cases death in dogs and cats.
- Yew: Nearly all parts of the plant (except the fleshy red aril) contain taxine alkaloids that are toxic to most mammals.
Safer alternatives for pet-friendly deck surrounds include roses, sunflowers, snapdragons, zinnias, Boston ferns, and most ornamental grasses. Herbs like basil, thyme, and rosemary are generally safe for dogs and cats and can be planted along deck edges where they receive plenty of sun.
Designing for the View From the Deck
One thing people often overlook when planting around a deck is that the primary viewpoint is from above and at a seated angle, not from ground level. This changes what works visually. A plant that looks fine when you walk past it at eye level might present nothing but bare stems and mulch when you glance over the railing from a chair.
Plants with broad, horizontal foliage or large flower heads read better from a deck than narrow, upright plants. Hostas, for instance, are mediocre when viewed from eye level in a garden bed, but their huge leaves look lush and tropical seen from a deck two or three feet above. Similarly, groundcovers and low-spreading plants that would be invisible in a tall border become a visible tapestry when you are looking down at them.
Fragrance is another factor that matters more around a deck than in a general garden border. When you are sitting outside in the evening, scent carries directly from nearby plantings. Gardenia, jasmine, and nicotiana (flowering tobacco) all release fragrance most intensely in the evening, which makes them particularly well suited to the area immediately around a deck used for dining or relaxation. Lavender and roses release scent throughout the day and reward anyone sitting nearby.
Finally, consider what the planting looks like at night. If the deck has lighting, plants with white or pale flowers, silver foliage, or variegated leaves will catch the light and remain visible after dark. White-flowering hydrangeas, silver-leaved artemisia, and variegated hostas all glow in low light. Dark-flowered plants essentially vanish once the sun sets, which limits their contribution to the evening atmosphere of a well-used deck.
How Close to Plant to the Deck Structure
Planting too close to a deck causes problems that take years to surface. Shrubs and trees planted right against the deck frame trap moisture against the wood, which accelerates rot and encourages mold and mildew. Roots from vigorous plants can work their way under footings and, over time, shift post supports. Dense foliage in contact with the deck also creates harborage for insects, including carpenter ants and termites that may eventually move into the structure itself.
A buffer of at least two to three feet between the trunk or main stems of any shrub and the nearest structural element of the deck is a reasonable minimum. For trees, the clearance should be wider, ideally at least half the expected canopy spread. This space can be filled with low groundcover, gravel, or mulch so it does not look like a bare gap.
Raised beds built alongside the deck are a popular solution because they give you control over soil quality and root direction while keeping plantings at a defined distance from the structure. A raised bed made from stone, steel edging, or rot-resistant lumber can double as extra seating when capped with a wide, flat top. Just make sure the bed drains away from the deck, not toward it.
