Stem count for wedding flowers: method and example

Start from the pieces, not the guest count

The guest count gives the number of tables, so of centrepieces. It says nothing about the quantity of flowers: a low five-stem centrepiece and a sixty-stem arrangement are not counted alike.

So start by listing every piece in the quote: bridal bouquet, bridesmaid bouquets, buttonholes, ceremony, centrepieces, top table, arch, staircase. Note the planned quantity for each.

Stems per piece: guidelines, not rules

Florists publish very different orders of magnitude depending on the flower, the vessel and the style. As an indication: about 15 rose stems for a small compact bridal bouquet and at least 25 for a fuller one (David Austin), 18 to 30 stems for a medium to large hand-tied bouquet, and 10 to 15 stems for a bridesmaid bouquet (Mini Falls Farm).

For centrepieces the spread is even wider: 3 to 7 stems per small vase, 25 to 30 stems for a medium centrepiece, 30 to 60 stems for a low, full arrangement, and more than 60 for a tall piece (Mini Falls Farm, Golden Florals). The flower changes everything: a bouquet of large blooms such as dahlias needs far fewer stems than one of small ranunculus.

Use these guidelines to check that a figure is not absurd. To order, use your own recipes: what you actually put in a piece, measured on your previous work.

Worked example for a 120-guest wedding

Assumptions in this example: three varieties (roses, ranunculus, eucalyptus), 15 tables of 8, 10% waste and bunches of 10 stems. In brackets: stems per piece (roses, ranunculus, eucalyptus). These are calculation assumptions, not industry averages.

Add waste, then round up to the bunch

Some stems will be damaged, too short or discarded when sorting. Add a waste allowance to each variety: it depends on the flower, the season and your supplier. The best approach is to calibrate it on your own observed losses.

One last adjustment: rounding. A bunch cannot be ordered in pieces, so you always round up. Packaging varies by flower and wholesaler (bunches of 5, 10 or 20, boxes, buckets): check the selling unit before calculating.

Adapting the count to style and flowers

The same centrepiece does not need the same number of stems depending on the flower. A peony or a dahlia fills a vase with three or four stems; the same silhouette in ranunculus or small roses takes ten or twelve. That is why a recipe is always noted per variety, never as a total number of stems.

Also separate three families: main flowers, which set the colour and the price; secondary and filler flowers; and foliage. Foliage often means many stems for little money: on an arch or a garland it can account for more than half the stems, and it is ordered in larger bunches.

One last sanity check: divide the total stems by the guest count and compare with your previous weddings of the same style. A large gap is not necessarily a mistake, but it deserves a second look at the recipe concerned before ordering.

Mistakes that skew the count

• Counting stems from the quote instead of the finished design: a piece that changes during assembly changes the quantity.
• Forgetting small pieces: buttonholes, corsages, toss bouquets, car decoration.
• Applying the same waste to every variety: a fragile or short-season flower is lost more often.
• Ignoring substitutions: if a variety is missing at the wholesaler, the stems must be recounted for the replacement flower.
• Trusting quantity charts found online: they come from other styles, other flowers and often other countries.

Turn these quantities into material cost and a selling price

Check before ordering

1. 1

   Reread the list of pieces

   Compare it with the signed quote and any amendments: number of tables, added guests, removed pieces.

2. 2

   Check the recipes

   Does each piece have its stems per variety, with no duplicates or gaps?

3. 3

   Group by variety

   Add up the stems of the same flower and colour across all pieces.

4. 4

   Apply waste, then the selling unit

   Then round up to the wholesaler's bunch or box.

5. 5

   Plan a plan B

   Note an acceptable replacement flower for each at-risk variety and recalculate it.
