Everything You Need to Know About Arbors
A living archway of vines creates a welcoming entrance and adds depth to any garden.
An arbor is a timeless feature that instantly elevates any garden, framing entrances, walkways, or focal points with a graceful arch of blooms or foliage. More than just decorative, arbors provide structure, support for climbing plants, and a welcoming sense of arrival. This in-depth guide covers everything you need to know about choosing, placing, planting, and maintaining an arbor in your landscape.
What Is an Arbor?
An arbor is a vertical garden structure made from wood, metal, or occasionally other materials. It typically forms a passage or entryway, consisting of two sides and a curved or angular top. Unlike flat trellises that act like walls, arbors serve as gateways, drawing the eye to a new garden ‘room’ or view beyond. Whether minimalist or ornate, an arbor adds instant charm and definition to outdoor spaces, becoming both plant support and sculptural accent.
Common Styles of Garden Arbors
The beauty of arbors is their versatility. From classic arches to boldly modern shapes, each style serves a different function â and sets a distinct mood. Here are the most popular arbor styles and what makes each unique:
Arched Arbors
Arched arbors are the style most commonly seen in both traditional and contemporary gardens. Defined by two flat sides that rise to meet in a gentle overhead curve, arched arbors can be made from wood, iron, or steel. Grid or latticework side panels provide plenty of grip for eager tendrils.
- Showcase the structure: Plant sparsely to let ornate details peek through climbing greenery.
- Let plants shine: Cover with vigorous vines or roses for a lush, flower-draped entryway.
Best plants for arched arbors:
- Passionflower
- Clematis
- Jasmine
- Nasturtium
- Coral honeysuckle
- Climbing rose varieties
Pair the structure to your garden’s style. Sleek iron arches complement modern spaces, while rustic wood brings warmth to a cottage garden.
Moon Gate Arbors
Moon gate arbors feature a dramatic circular or semi-circular opening, wider than standard arches and visually striking. Derived from traditional Chinese garden design, moon gates symbolize birth, renewal, and the unending cycle of life. Their open, sculptural form makes them ideal for larger spaces or as statement entryways, especially in contemporary or Asian-inspired landscapes.
- Typically constructed of metal with ladder-like slats for light vines.
- Look stunning standing alone as a garden sculpture, or cloaked in green.
- Great for creating a âhallwayâ of layered arbors for dynamic garden entrances.
Best plants for moon gate arbors:
What others are reading
- Annual or non-woody vines such as sweet pea and clematis
- Tender perennial vines for quick seasonal cover
Design tip: Place multiple moon gate arbors in succession, spaced three to five feet apart, for a stunning, tunnel-like entrance. Plant evergreen or twining vines to maintain visual interest year-round.
Grape Arbors
Grape arbors are defined by their flat-topped, pergola-like structure, originally intended to support the heavy, woody vines of grape plants. Characteristically robust and constructed from wood, they serve as solid supports for all manner of vigorous, weighty climbers.
- Excellent as outdoor dining canopies or ‘living tunnels.’
- Especially well-suited for edible landscapes or âbackyard vineyards.â
- Can stand up to demanding, fast-growing species.
Best plants for grape arbors:
- Grapevines (obviously)
- Wisteria
- Trumpet vine
These arbors create impressive shade and lend a Mediterranean feel, especially when paired with outdoor seating beneath their leafy canopy.
Gabled Arbors
Gabled arbors feature steeply pitched, triangular tops â evoking the angular silhouette of classic cottage rooftops. Usually constructed from wood, their crisp lines and symmetry are a hallmark of English garden design.
- Allow intricate rooflines to show by trimming back exuberant vines.
- Add a sense of architecture and sophistication to the landscape.
Best plants for gabled arbors:
- Climbing English roses (hold shape, donât overwhelm the roofline)
- Clematis
- Hummingbird vine
- Black-eyed Susan vine
Design tip: Use pruning to keep coverage neat and architectural, allowing the pointed roof to remain visible for dramatic effect.
Where to Place an ArborâAnd Design Considerations
The placement of an arbor has a big impact on both its function and its visual appeal. Thoughtfully sited arbors can:
- Frame a garden gate or entry, marking the transition from street to sanctuary.
- Create a focal point at a pathâs end, drawing visitors deeper into the landscape.
- Divide garden ‘rooms,’ guiding movement and changing perspective.
- Add vertical interest to flat, open spaces.
When deciding on a location, consider:
- Sun exposure: Most climbing plants require full to partial sun.
- Viewpoints: Position where it can frame a cherished view or entrance.
- Function: Passages should be tall and wide enough (at least 6 feet high and 3 feet wide) to comfortably walk beneath.
- Proportion: Ensure the structure is scaled to your spaceâan oversized arbor can overwhelm a small garden, while a petite one may be lost in an expansive yard.
Choosing Materials: Wood, Metal, and Beyond
Material selection defines both the style and longevity of your arbor. The two main contenders are:
| Material | Pros | Cons |
|---|---|---|
| Wood | Classic look; blends with natural surroundings; can be painted or stained; easy to customize. | Prone to rot/decay; needs regular maintenance (sealant, paint); may be susceptible to pests. |
| Metal (Iron/Steel) | Durable; sleek, modern aesthetic; low maintenance (if powder-coated); handles heavy vines well. | Higher upfront cost; may rust if coating fails; can heat up in full sun, affecting sensitive plants. |
| PVC/Composite | Weather-resistant; very low maintenance; clean, crisp lines; does not rot. | Less traditional appearance; can lack the charm of natural materials. |
Match the material to both your plant choices and your gardenâs overall design. Wood and iron are traditional favorites, but PVC and even stone can work in certain landscapes.
Climbing Plants: The Best Choices for Arbors
The real magic of an arbor comes alive when itâs covered in living, climbing plants. The right plant choice depends on your climate, sunlight, and how much upkeep youâre willing to do. Here are some favorites for fast, showy coverage:
- Roses: Especially climbing and rambling varieties, for continuous blooms and fragrance.
- Clematis: Prolific flowering and range of colors; works with most structures.
- Honeysuckle: Fast-growing and bird-attracting; sweet-scented in bloom.
- Jasmine: Fragrant, delicate blooms, best for warmer regions.
- Wisteria: Dramatic flower clusters and lush foliage; ideal for robust structures (like grape arbors).
- Sweet pea: Non-woody annual; quick seasonal coverage and strong fragrance.
- Nasturtium: Edible flowers and foliageâgreat for informal or kitchen gardens.
- Trumpet vine: Vigorous, hardy, and attractive to pollinators.
- Black-eyed Susan vine: Cheerful annual for smaller or lightly covered arbors.
Train vines using soft ties or clips, guiding them gently up and over the structure. Prune regularly to maintain shape, encourage flowering, and prevent your arbor from being overwhelmed.
Arbor Installation and Construction Tips
- Ensure your structure is anchored securelyâespecially in windy areas. Use ground spikes or deep-set posts for stability.
- Choose dimensions wisely. Allow a minimum entryway height of 6′ to 7′ and width of at least 3′; larger arbors may require more.
- Assembly is often straightforward and within reach for DIYers; prefabricated kits can simplify the process.
- Apply wood preservative or paint before assembly to ensure even, lasting protection.
- Metal arbors need corrosion-resistant coatings for longevity.
Design Inspiration: Making the Most of Your Arbor
- Frame a garden gate to mark the boundary between public and private, or to create a grand entrance to your landscape.
- Place an arbor at the start of a garden path for a whimsical ‘portal’ effect.
- Train vines to form a green tunnel by installing multiple arbors in a row.
- Add seating by choosing an arbor with an integrated bench, creating a restful spot entwined with greenery.
- Incorporate lighting for magical nighttime effects.
Caring for Your Arbor: Maintenance Essentials
- Inspect regularly for rot, rust, or loose fastenersâespecially after severe weather.
- Reapply wood preservative or paint as needed (annually or biannually).
- Prune and tie back vines to keep growth healthy and balanced.
- Clean away dead leaves and debris to prevent moisture damage and pest infestation.
- Consider seasonal disassembly for lightweight, portable arbors in climates with harsh winters.
Arbor vs. Pergola vs. Trellis: Whatâs the Difference?
