Let’s be honest — the world of outdoor design can get a little confusing. You start out just wanting “something nice for your outdoor living space,” and suddenly you’re googling things like what’s the difference between an arbor and a pergola?
At The Site Group, we work with homeowners every day who want to create beautiful outdoor spaces but aren’t quite sure where to start. And when it comes to structures like arbors and pergolas, the lines can get a little blurry. They both have posts, they both support plants, they both look great in pictures… so what’s the real difference? And more importantly — which one is right for your space?
This guide walks you through the key differences, covers practical uses and provides real-life inspiration for each, so you can feel confident about your next outdoor project.
What Is an Arbor?

Think of an arbor as a beautiful little welcome sign for your outdoor space.
Typically smaller in size than a pergola, an arbor is a freestanding structure made of two or four posts with a curved or flat top — and often, lattice sides. You’ve probably seen one framing a garden path or tucked between hedges, maybe even covered in flowering vines like clematis or climbing roses.
It’s the kind of feature that feels like a natural invitation to slow down and step into something special.
Arbors are most often used:
- At the entrance to a garden or walkway.
- As a decorative focal point in a landscape.
- To support vertically growing plants or vines.
- To create a sense of transition between spaces.
They’re typically built from wood, metal or vinyl and range in width from about 3 to 6 feet — just wide enough to walk through. While they don’t offer much shade, arbors do offer impact. They’re small but mighty in their ability to frame a view, soften a hardscape or add that charming garden feel.
At The Site Group, we love using arbors as part of a larger design plan. Whether it’s the entryway to a custom patio or a quiet path through the garden, an arbor can signal the start of something special — and help tie your landscape together with elegance and intention.
What’s the difference between a trellis and an arbor?
It’s a great question — and one we get all the time. While trellises and arbors are often mentioned together (and even used together), they serve different purposes in your landscape design.
Here’s a quick breakdown:

A trellis is often used purely for plant support — think of it as a vertical garden aid. You’ll often see it attached to a wall or fence, giving climbing plants like jasmine, ivy or clematis a place to grow upward.
An arbor, on the other hand, is a more architectural element. It frames a space, defines an entry and adds a sculptural quality to your landscape — all while still supporting climbing plants if desired.
At The Site Group, we sometimes incorporate both into a single design. For example, a custom arbor may include trellis panels on the sides for a lush, green look with structure and style.
So while they’re different, they work beautifully together, especially when thoughtfully designed as part of a cohesive outdoor living plan.
What Is a Pergola?

If an arbor is the charming entryway to your garden, a pergola is the grand outdoor room where life happens.
A pergola is a larger, more substantial structure typically made with four sturdy posts and an open, slatted roof. It’s designed to define a space — usually for lounging, dining, entertaining or simply relaxing outdoors — and it brings both form and function to your backyard.
You’ll often find pergolas:
- Over a patio or deck to create shade and structure.
- Next to a pool or outdoor kitchen for added comfort and elegance.
- As part of a larger landscape design to define gathering areas.
- With added features like fans, lighting, heaters or even retractable canopies.
While pergolas don’t offer complete protection from the elements, their slatted roof provides filtered light and a cool, airy atmosphere. And with the right design (and a little help from climbing plants or weather-resistant drapes), they can provide both style and shelter.
At The Site Group, we design custom pergolas that do more than look beautiful: They integrate seamlessly into the flow of your space, reflect your home’s architecture and serve the way you live. Whether you’re hosting family dinners under string lights or enjoying a quiet brunch with a coffee and a breeze, a pergola can turn your backyard into a place you can actually use.

Can you grow plants on a pergola?
Yes, and it’s one of the most beautiful ways to bring your pergola to life.
Pergolas are perfect for supporting climbing plants, which can soften the structure, add privacy and create a lush, natural canopy overhead. With the right selections, your pergola can become a living, breathing part of your landscape that changes with the seasons.
Here are a few popular plants that thrive on pergolas:
- Clematis: Fast-growing and colorful, great for partial sun
- Wisteria: Dramatic blooms and a stunning look (though it needs strong support and regular pruning)
- Trumpet vine: Attracts hummingbirds and adds bold color
- Honeysuckle: Fragrant and fast-growing with sweet-smelling blooms
- Grapevines: For a vineyard feel, plus the bonus of fresh fruit
If you love the idea of a pergola covered in greenery, our team at The Site Group can recommend the right plants for your soil, sun exposure and maintenance preferences — and incorporate them seamlessly into your overall design. We’ll even make sure your structure is built to be sturdy enough to support mature vines long-term.
It’s all part of turning your backyard into a functional, beautiful and truly immersive outdoor experience.

Which Is Right for You? Key Questions to Ask
Still not sure whether an arbor or a pergola is the better fit? That’s totally normal. They each bring something special to a landscape.
To help you choose with confidence, here are a few simple questions to consider:
1. How do you plan to use the space?
- Just want to add charm or mark an entry point? An arbor is likely all you need.
- Want to lounge, dine, entertain or enjoy shade? A pergola is the better choice.
2. Do you need function, form or both?
- Arbors are mostly decorative and help guide the eye.
- Pergolas provide shade, structure and can even accommodate fans, lighting or a retractable canopy.
3. What size and scale fits your yard?
- A small garden or side yard may only need an arbor.
- Larger backyards or patio spaces often call for a pergola to create a distinct outdoor living area.
4. What’s your timeline and budget?
- Arbors are quicker to install and require a smaller investment.
- Pergolas are a more significant investment, but they can transform your outdoor space into a usable, functional space.
5. Are you thinking long-term?
- An arbor is a lovely accent, but it won’t add functional square footage.
- A pergola can increase the livable footprint of your property and even boost resale value.
At The Site Group, we always start by asking the right questions, because that’s what turns a good design into a great investment. Whether you’re just looking to enhance your garden or ready to build an outdoor living space that becomes the heart of your home, we’re here to help you choose what fits best.
