Preserving the LEGO Botanicals Flower Arrangement (10345): Build Notes and a Display Case

LEGO's Botanical Collection has changed how adults think about brick building, turning plastic bricks into real home décor that doesn't look out of place next to actual houseplants. The newest addition is the LEGO 10345 Flower Arrangement — a mix of the deep red Night Rider Camellia, bright yellow Persian Buttercups and a striking purple Hydrangea that makes for a genuinely eye-catching centerpiece.

As any veteran builder knows, finishing the build is only half the job — keeping it looking good afterward is the real challenge, especially with a set built from this many small, delicate pieces. Here's a look at how this set comes together, and the display case we built to protect it.

The Build: Patience and Petals

Putting the 10345 set together is an engaging, multi-stage process. Based on builder feedback and our own look at the construction, here's how it unfolds.

Phase 1: The Chalice Vase

The build starts with the earth that holds the flowers, not the flowers themselves. Using SNOT (studs not on top) techniques, you build a solid inner core layered with smooth white slopes. The vase feels genuinely sturdy as it comes together, which matters, since it needs to support a heavy canopy of greenery and blooms later on.

Phase 2: The Sunlit Blooms

Next comes color. Building the Night Rider Camellia and Persian Buttercups is straightforward and satisfying — curved panels and modified plates bring the bright yellow and deep red elements together quickly, and the stems start to look like a real garden fast.

Phase 3: The Purple Hydrangea, or the Butterfly Challenge

This phase tests your patience more than any other part of the build. The purple hydrangea is the visual anchor of the set, and it's genuinely delicate to build, with a pace that's completely different from the first two phases.

Instead of standard flower pieces, the designers used dozens of tiny purple butterfly elements to build up the clustered look of hydrangea petals. Each one has to be angled carefully onto a spherical dome so the wings overlap without colliding — press too hard on one, and a few others can pop off, so it pays to work slowly here.

By the time the purple dome is finished, you're holding a beautiful but fragile floral piece, and docking it into the vase is a moment that takes a steady hand and a bit of patience of its own.

Why You Shouldn't Leave It Exposed

After spending hours placing fragile butterfly wings and delicate leaves, leaving this set out on a coffee table is a real risk.

Dust collects fast: the 10345 set has thousands of small crevices, especially around the hydrangea and baby's breath. A dusting brush will almost certainly knock a butterfly piece loose.

Colors fade: the vibrant yellow and purple bricks are prone to discoloring under regular sunlight exposure.

If you're deciding how to display a set this fragile, leaving it in the open isn't really an option — it needs real protection.

Our Solution: A Museum-Grade Floral Case

A set this detailed deserves a proper display case. Ours is built to turn the 10345 into a showcase piece rather than something left exposed on a shelf.

99% dust-proof: the acrylic panels interlock to seal out dust completely, so you never need to brush those fragile butterfly wings again.

Optical-grade clarity: made from pure casting acrylic with 98% light transmittance, so the yellows and reds stay vivid under any lighting, with no cloudy distortion.

UV protection: the SGS-certified acrylic filters out UV rays that would otherwise yellow the bricks over time.

Built to match your other cases: like the cases we make for model cars, this one has a sleek, high-gloss black base that anchors the bright colors and fits alongside the rest of your LEGO Icons collection.

Whether it's going in a minimalist office, a cozy living room, or a dedicated display gallery, this case gives you both protection and a better-looking setup.

Frequently Asked Questions

Will this case fit other sets in the Botanical Collection? While it's sized for the sprawling leaves of the 10345 Flower Arrangement, the case has enough room for other mid-to-large floral sets too, like the Bouquet of Roses or the Orchid.

Is the case hard to assemble? Not at all — unlike the hydrangea build, this is a tool-free, snap-fit case. You can have it assembled in under three minutes.

How do I clean the acrylic? A soft, damp microfiber cloth is all you need. Avoid ammonia-based glass cleaners, which can dull the surface.
