Arch vs Arbor vs Trellis: Choosing the Right Giant Flower Frame

Key Takeaways
A wedding arch has a curved top and is typically freestanding — it's designed to frame a couple or a focal point with that iconic sweeping shape. An arbor is more like a small garden structure with posts and a flat or pitched roof, creating more of a doorway or canopy effect.
Both are walkthrough structures, but the arch is more dramatic and photogenic from the front, while the arbor creates a more immersive "entering a space" experience. For giant flower installations, arches are easier to decorate; arbors require more flowers but offer that stunning canopy option.
For a standard 8-foot arch, plan on 10–15 giant flowers for good coverage. Mix sizes — a few large 4-foot statement flowers at the top and sides, filled in with 2–3 foot blooms. If you want a fully lush, no-gaps look, go closer to 15–20 flowers.
Our Bundle Kits (8–12 flowers) are designed to give you a solid foundation for an arch. Many customers order one bundle kit plus 3–5 individual kits to complete the look.
Yes — EVA foam is weather-resistant and holds up well outdoors. It won't wilt, brown, or lose petals in heat or humidity the way fresh flowers do. That said, direct prolonged sun exposure over many hours can cause slight color fading over time.
For outdoor events, make sure your frame is properly weighted and secured. Wind is the bigger concern than weather — giant flowers have significant surface area and can act like sails in a strong breeze. Weight your bases and stake your frames whenever possible.
Is a trellis strong enough to hold giant foam flowers?
Yes, absolutely. EVA foam flowers are surprisingly lightweight — even a 4-foot flower typically weighs under 2 pounds. A standard wire grid trellis panel can easily support 10–15 giant flowers without any structural issues.
The key is using proper attachment — zip ties through the grid openings rather than just resting flowers against the trellis. For wall-mounted trellises, make sure your wall anchors are rated for the combined weight of the trellis and all flowers.
The trellis wins for portability — panels are flat, lightweight, and quick to assemble. A PVC arch is a close second; the pipes break down into manageable lengths and the whole frame can fit in a standard SUV.
Arbors are the most challenging to transport solo because of their size and weight. If you're doing multiple events or working alone, I'd lean toward an arch or trellis system for practicality.
Absolutely — and a lot of our customers do. PVC pipe arches are a popular DIY project that can be built for under $50 in materials. There are great tutorials on YouTube for PVC arch frames in various sizes. For arbors, basic woodworking skills and a weekend afternoon are usually all you need.
What I always tell people: invest in the flowers, not necessarily the frame. A simple DIY PVC arch covered in stunning giant EVA foam flowers looks just as impressive in photos as a $400 metal frame. The flowers are the stars of the show.
At the end of the day, there's no universally "best" choice in the giant flower arch vs arbor vs trellis debate. There's only the best choice
