Preserved flowers for window and retail displays
VivaPetal supplies the preserved material a window set is built from — hydrangea in 30+ stock shades, moss in 16+ colours on 30 × 30 cm sheet panels, structural dried material for silhouette. A window is still a hard environment pretending to be a soft one: hot, bright, unventilated, and expected to look the same on the ninetieth day as on the first. This guide is written for the people who build those sets — visual merchandisers, display studios, event contractors, and the buyers at hotels and concept stores.
Why preserved material suits a window and a shop floor
A fresh window needs a regime: a water source, a visit schedule, a rebuild the week something dies, and a budget line for all three. Preserved material removes the regime. It arrives conditioned, it is installed once, and after that it asks for nothing.
The second advantage is structural. A stabilised stem holds the angle it was set at and heads do not droop, so the lines you drew on the elevation are still the lines in the window six weeks later. The third is repeatability: the same reference, grade and production run gives a rollout across several sites a set that reads as one set. Where the material comes from is covered in our guide to sourcing preserved flowers from Kunming, and the same logic carries into reception desks and lobby planters — see the interior projects in our applications overview.
What preserved material is not is indestructible. Indoor conditions, sensibly handled, give three to five years. A window is not sensible conditions, and the next section is the honest version of why.
The one real risk in a window: direct sun
Every dye fades. Not some dyes under some conditions — every dye, given enough light and enough time. Preserved flowers are coloured with pigment that sits in a real petal, and ultraviolet light breaks that pigment down. Behind glass, in a sun-facing window in summer, the process is measured in months, and you see it as a general softening of the colour rather than a change you can point at.
Undyed natural references move too. They do not fade to white, they brown: pale greens and naturals drift warm, and a set built from them reads muddier by the end of a long season than it did at installation.
This is not a fault in the material and it is not something a supplier can dye around. A preserved flower that holds its colour indefinitely in direct sun is either a different product or a supplier who has not looked at their own returns.
What you can do is modest but real. Set the piece back from the glass — the further a set sits from the pane, the less UV it takes and the cooler it runs. Push the strong colour into the interior, where shop-floor tables and counters hold it far longer, and plan the window as a rotation with the replacement budgeted in. Tell us the orientation and the hours of direct sun the position takes, and we will advise which references to put where.
Volume and structure: what to specify
A display is built out of jobs, not out of flower names. Four jobs cover most windows: mass, surface, structure and air. Specify the job and the material follows; specify a list of flowers and you get a bouquet in a box.
| Job in the set | Material | What it does |
|---|---|---|
| Mass | Hydrangea, 30+ stock shades | Fills a field quickly and hides the mechanics underneath |
| Surface | Moss, 16+ colours, 30 × 30 cm sheet-mounted | Reads as a plane rather than a plant |
| Structure | Dried pods and branches — lantern pods, lotus, willow curls, palm | Gives silhouette against glass, where shadow is part of the design |
| Air | Fillers and accents | Breaks up the mass and lets light through the middle |
Mass is the expensive job and the one most often underestimated. A window is read from the pavement at several metres, so the viewer sees a shape and a colour field long before an individual flower. Build the field first, then place focal material into it: a few rose heads in the right position do more than a hundred scattered through the set.
Structure is what makes a window look designed rather than stocked: branches close to the pane cast shadow into the set behind them, and that shadow is free depth.
Panels and colour across a display
Sheet-mounted moss is the format that makes a large field practical: 30 × 30 cm panels, backed and ready to fix, in 16+ stock colours including mixes of two or three tones. Panels suit a regular field where the surface is a background; loose moss by weight suits irregular shapes and blending on site, at much higher labour — the trade-off is set out in our guide to specifying a preserved moss wall.
The rule that decides whether a set looks deliberate is the run. Colour is dyed, not inherent, so two separate runs of the same recipe read slightly different side by side. On one panel nobody notices; across a window, a back wall and two interior tables it is the first thing a good merchandiser sees. Order the whole display as one run, and if the installation is phased, tell us the total at the outset so it can be sized and held together.
Judge the palette in the window, not in the studio. Glass, street light and the shopfront floor all shift how a reference reads. Where a colour has to be exact, the workflow runs through a physical reference, a sample and your approval under your own light; the terms behind it are defined in the preserved flower glossary. Keep the palette short — three to five references will hold a window, twelve will not. For a scheme built around one event rather than a season, see the guide to preserved flowers for wedding florists.
Freight, installation and lead time
Preserved material is light for its size, which means most of what you pay to move is air. Air and courier charge the greater of actual weight and volumetric weight — length × width × height in centimetres divided by the carrier's divisor, usually 5000 or 6000. A carton larger than it needs to be bills on volume, so the carton plan matters more than the kilos. You get dimensions and chargeable weight with the quote, which is the point at which your forwarder can price the move properly.
One shipment for the whole display is usually right: it keeps the colour in one run, produces one set of documents, and means the crew works from one delivery rather than chasing a carton that clears late. Build in sections off site, and check the opening for square before the material ships — panels cut to a drawing will not forgive it.
Lead time depends on the references, the quantity and the production slot, and we confirm it per order with the quotation rather than publish a date that will be wrong by the next enquiry. Retail calendars are not flexible: demand builds ahead of Christmas and Mother's Day, so give us the install date with the enquiry. Delivery is quoted EXW (Kunming) as our default, FOB where you have a forwarder at the port, then DAP — tell us the destination and we will confirm the workable term.
Common questions
Display questions buyers ask
Yes, in direct sun. Every dye fades under ultraviolet light, and behind glass the process speeds up. You usually see a general softening of colour over a season rather than a sudden change. Set the piece back from the pane and plan the window as something with a working life.
It depends on how much of the window is a field and how much is accent, and on the depth you want the surface to stand at. Send the elevation with dimensions, the viewing distance and a note on which zones are mass and which are detail, and we will quote per reference rather than one lump figure.
Often, yes. The stock palettes are 36+ rose shades, 30+ hydrangea shades and 16+ moss colours (as of October 2026), and a brand colour frequently lands close to one of them. Where it does not, custom dyeing is a development job with a sample and your approval before production.
Usually, if it comes down clean, goes back into a sealed carton and is stored away from light and heat rather than in a damp stockroom. A set that has spent a season in a sunlit window will have moved, so re-check it against a fresh reference before it goes out again.
