Flowering your own wedding sounds like a florist-sized job. Broken into pieces and counted stem by stem, it becomes a shopping list you can tick off from the sofa, weeks before the day, with faux blooms that will not wilt while you work.

Plan by the stem, not by the feeling
The single most common mistake in DIY wedding flowers is buying by the eye and running short two days before, when there is no time to reorder. The fix is to plan the way a florist quotes: count the finished pieces you need, look up how many stems each one takes, add the numbers together, then add a little more. Faux flowers make this painless, because leftovers keep forever in a cupboard and cost nothing in a cooler while you decide.
Start by writing down every arrangement the day actually needs. A typical wedding uses a bridal bouquet, a posy for each bridesmaid, a buttonhole for the groom and groomsmen, a corsage for the mothers, something at the ceremony (an arch, a pair of aisle markers, or both), petals for the aisle and tables, a centrepiece for each guest table, and a few finishing pieces such as a welcome-sign arrangement, cake flowers and a door wreath. Once that list exists, the maths is simple.
The golden rule: round every number up. A bouquet with a few spare roses always photographs fuller than a thin one, and unused faux stems become next year's mantel arrangement rather than compost.
The master quantity table
These are working florist estimates for medium-sized, generously full pieces. If your style is loose and airy, lean to the lower number; if you want lush and packed, take the higher one. Greenery is counted in bunches or garlands, since it is used to fill and soften rather than to headline.
| Piece | Roses / blooms | Greenery | Petals | Notes |
|---|---|---|---|---|
| Bridal bouquet | 24–30 stems | Small handful | — | One box of 25 usually does it |
| Bridesmaid posy (each) | 12–15 stems | A few sprigs | — | Half a box splits across two |
| Boutonniere / buttonhole (each) | 1 bloom | 1 sprig | — | Or a ready-made set of 6 |
| Wrist or pin corsage (each) | 1–2 blooms | 1 sprig | — | Or a ready-made set of 6 |
| Ceremony arch (full) | 30–40 stems | 2–3 garlands | — | Cluster at two corners, trail the rest |
| Aisle marker (each) | 6–10 stems | 1 bunch | — | Pew ends and chair backs |
| Low centrepiece (each) | 12–18 stems | 1 bunch | — | A combo box fills one on its own |
| Tall centrepiece (each) | 18–24 stems | 1–2 bunches | — | Weight the vase base |
| Aisle & table scatter | — | — | 300–600 petals | One bag per 10 feet of aisle |
| Welcome sign / door wreath | 1 wreath | Built in | — | Hang and go |
To turn this into a shopping list, multiply the per-piece figures by how many of each you need, then divide by the box size. Twenty-five roses to a box means a bridal bouquet plus two bridesmaid posies come out of roughly two boxes, with stems to spare.
Bouquets and the wedding party
The bridal bouquet is the piece every photo comes back to, so it earns the fullest count. Around 24 to 30 blooms gives a hand-tied bouquet real presence without becoming heavy to hold through a ceremony. Mix two or three flower shapes for a garden feel: open real-touch roses as the headline, a few peonies for softness, and slim filler such as ranunculus or cosmos for movement. If you would rather not source separate flowers, a rose and peony combo box arrives pre-mixed in one palette and builds a bouquet straight from the box.
Bridesmaid posies are simply smaller versions, about 12 to 15 stems each, and they read best in the same palette at a slightly lighter or deeper tone than the bride's. For the rest of the party, skip the fiddly morning assembly and use ready-made sets: a box of six boutonnieres covers the groom, groomsmen and fathers with matching blooms, and a set of six wrist corsages handles mothers and grandmothers. Because the flowers are faux, every one of these can be assembled days early and kept as a memento afterward. Browse the whole party in The Details.
The ceremony arch
The arch is where a plain metal or wooden frame becomes the backdrop of every ceremony photograph, and it takes less than most people fear. The two ingredients are fabric and flowers. Start with chiffon draping fabric, which swags over the frame and catches the light in a soft wash of colour; a single long panel gathered at the top and left to trail on one side is a classic, uneven-on-purpose look.
On top of the fabric, add greenery and blooms. Wind one or two eucalyptus garlands along the frame first to give the flowers something to sit against, then cluster 30 to 40 roses and larger blooms at one or both corners where the eye lands. You do not need to cover the whole arch: a heavy corner cluster that thins into trailing greenery reads more expensive than an evenly-dotted frame. Shop the pieces together in Arches & Draping and Greenery & Garlands.
The aisle and the petals
Petals do a surprising amount of work for their price. A scattering down the aisle, around the ceremony space and along the reception tables ties the whole room to your palette for very little effort. Faux silk rose petals come 300 to a bag, and one bag comfortably dresses about ten feet of aisle or a long table runner. They will not brown in the heat, will not stain an ivory runner, and can be set out the night before, then swept up and kept for the next celebration.
For aisle markers, a small cluster of six to ten stems tied to a chair back or a shepherd's hook every few rows frames the walk without crowding it. Match the marker flowers to the bouquet, and if your venue allows, scatter a light trail of petals between them so the eye is led all the way to the arch.
Centrepieces and the tables
Centrepieces are usually the largest line on the list simply because there are so many tables. Decide first between low and tall. Low arrangements, around 12 to 18 stems in a shallow bowl or compote, keep sightlines open for conversation and are the safer choice for most rooms. Tall arrangements, 18 to 24 stems lifted on a vase or candlestick, make a dramatic ceiling-height statement but need a weighted base so they do not tip. A combo box fills one low centrepiece on its own; for a run of tables, buy roses and greenery by the box and split them evenly.
The finishing pieces are small but photograph often. A single low arrangement or a peony and hydrangea wreath dresses the welcome-sign or guest-book table, a few loose blooms laid at the base of the cake echo the bouquet, and a wreath on the venue door greets guests before they are inside. Being faux, every one of these is built in advance and reused long after the day.
Build your palette
The reason a florist's flowers look considered is restraint: three or four shades, repeated everywhere. Because Floroom mixes every colour across roses, petals, greenery and drapes, you can settle on one palette and carry it from the arch to the aisle to the tables without a single mismatch. Here are four that always work, with the shades to search for.
Timeless
Blush and ivory roses with sage eucalyptus, finished in champagne. The safe, soft, always-elegant choice.
Moody & romantic
Burgundy, dusty rose and plum against deep forest green. Made for autumn, evening and candlelight.
Earthy & warm
Terracotta and burnt orange with warm taupe and olive. Perfectly at home at a barn, a desert or a boho garden.
Soft & cool
Dusty blue and lavender with cream and silver-green foliage. Fresh, airy and lovely for spring.
Pick one, then start from the roses, where the widest choice of shades lives, and match everything else to it. The shade picker on each product page shows exactly which colours a line comes in.
Build a bouquet in six steps
Once the flowers arrive, a bouquet takes about twenty unhurried minutes. There is no water, no floral foam and no clock, so you can stop, step back and start again as often as you like.
- Sort by role. Lay out your headline blooms, your softer secondary flowers, your slim filler and your greenery in four piles so you can reach each easily.
- Shape the stems. Bend each wired stem a little near the base so the heads angle outward rather than all facing straight up. This is what gives a bouquet its rounded, gathered dome.
- Start with greenery. Hold three or four sprigs in your hand as a loose base. The leaves give the flowers something to rest against and hide the mechanics later.
- Add the headline roses. Place them one at a time, turning the bunch in your hand a quarter-turn after each so the shape stays even all the way around.
- Fill and soften. Tuck peonies and filler into the gaps at slightly different heights, letting a few sit proud for a natural, un-manicured look.
- Bind and trim. Wrap the stems with floral tape, cut them to an even length, and finish with a length of silk ribbon tied to trail.
The faux timeline
The quiet superpower of faux flowers is time. Fresh wedding flowers arrive two or three days before and must be kept cold and handled at the last minute. Yours can be finished weeks ahead, boxed, and simply carried in. Here is a relaxed schedule that keeps the final week free.
| When | Do this |
|---|---|
| 8–12 weeks out | Settle the palette, write the piece list, and order flowers with a little extra |
| 4–6 weeks out | Build the bouquets, posies, boutonnieres and corsages; box and label each |
| 2–3 weeks out | Assemble centrepieces and aisle markers; wind the arch garlands |
| The week before | Pack everything by venue location; nothing left but delivery |
| After the day | Dust, lay flat in a box, and keep as a keepsake or for the next event |
Care, storage and keepsakes
Looking after faux flowers takes almost nothing, which is rather the point. Between uses, lay bouquets and arrangements flat in a shallow box away from direct sun, since strong light will fade any fabric over years. A light dusting now and then keeps them fresh; a hairdryer on the cool setting, held at arm's length, lifts dust from petals without bending them. If a stem gets crushed in storage, a moment near warm steam relaxes the fabric back into shape. Kept this way, a bouquet you carried down the aisle will still sit on the mantel a decade later, which is a keepsake fresh flowers can never be. Our story has more on why the range is built to last.
A worked example: flowering a 100-guest wedding
To see how it all adds up, here is a complete list for a mid-sized wedding of about 100 guests across ten tables, with a four-person wedding party and a draped ceremony arch, in a timeless blush palette. Adjust the counts up or down for your own day; the point is to show the method.
| For | Buy | Roughly |
|---|---|---|
| Bridal bouquet + 3 posies | Real-touch roses ×3 boxes | 75 stems |
| Bouquet softness | Peony stems ×1 | 16 stems |
| Party flowers | Boutonnieres + corsages | 2 sets |
| 10 low centrepieces | Combo boxes ×6 + roses ×4 | 10 tables |
| Table & centrepiece greenery | Eucalyptus stems ×4 | 4 bunches |
| Ceremony arch | Chiffon drape + garlands ×2 | 1 arch |
| Aisle & tables | Rose petals ×4 bags | 1,200 petals |
| Welcome & door | Peony wreath ×1 | 1 wreath |
That single order flowers the bouquet, the whole party, ten tables, the aisle, the arch and the door, and every piece is reusable afterward. Spread the assembly across a few evenings using the timeline above, and the busiest week of your life stays free of floral panic. When you are ready, start with the roses and let the palette lead.
