Wedding Flowers by Month: The Substitution Table

The wedding flowers people want most have the shortest seasons, and the ones available every month of the year are mostly the ones nobody asks for by name. Peonies are genuinely available for about two months. Dahlias for about three. Roses, carnations and alstroemeria are available all twelve — which is exactly why they end up in so many arrangements. This guide is the month-by-month table, and more usefully, the substitution table: for each month, what you will actually be offered when the flower you asked for is not in season.

Most seasonality guides stop at the season. That is not granular enough to plan with. A May wedding and a June wedding both sit in "late spring," but May is peak peony and June is the last call; an August wedding and an October wedding are both "autumn," but dahlias are climbing in August and finished by late October. The month is the unit that matters.

The month-by-month table

Month	At their best	Also available	Hard to get
January	Ranunculus, anemone, hellebore	Amaryllis, paperwhite narcissus, waxflower, camellia	Peony, dahlia, sunflower, most garden flowers
February	Ranunculus, anemone, tulip (early)	Camellia, waxflower, amaryllis	Peony, dahlia, sunflower
March	Tulip, daffodil, ranunculus, hyacinth	Muscari, anemone, camellia	Peony, dahlia, sunflower
April	Tulip, lilac, sweet pea	Ranunculus, hydrangea, early peony	Dahlia, sunflower, zinnia
May	Peony (peak), lily of the valley, poppy	Sweet pea, ranunculus, garden rose, hydrangea	Dahlia, sunflower, chrysanthemum
June	Peony (final weeks), garden rose, sweet pea	Hydrangea, ranunculus, delphinium	Dahlia, tulip, anemone
July	Sunflower, zinnia, Queen Anne's lace	Hydrangea, garden rose, early dahlia	Peony, tulip, ranunculus (winding down)
August	Dahlia (building), sunflower, zinnia	Queen Anne's lace, hydrangea, celosia	Peony, tulip, sweet pea
September	Dahlia (peak), marigold, aster	Chrysanthemum, sunflower, zinnia	Peony, tulip, lily of the valley
October	Dahlia (final weeks), chrysanthemum, marigold	Aster, camellia (starting), berries	Peony, tulip, sweet pea, sunflower
November	Chrysanthemum, berries, branches	Camellia, amaryllis, anemone	Peony, dahlia, most garden flowers
December	Amaryllis, paperwhite, berries, branches	Camellia, anemone, ranunculus (starting)	Peony, dahlia, sunflower, tulip

Two caveats that keep this table honest. First, availability is not the same as affordability: a flower can be technically obtainable out of season through import and still cost several times its in-season price. Second, imports change the picture at the edges — peonies grown in Chile and New Zealand reach the northern hemisphere in late autumn, which is why you occasionally see a November peony bouquet. It is available. It is not cheap.

The twelve-month list

These are available every month, which is why they form the backbone of most wedding work whether or not anyone planned it that way.

Roses, carnations, alstroemeria, baby's breath, lisianthus, orchids, calla lilies, gerbera daisies, freesia, stock, delphinium, iris, protea, scabiosa, veronica.

Year-round does not mean cheap. Roses are available all twelve months and still expensive, because demand is constant and garden and heirloom varieties are genuinely scarce. Carnations and alstroemeria are the actual budget workhorses. Lisianthus sits near roses in both look and price, which makes it the most common substitution for rose-shaped blooms.

The substitution table

This is the part that matters when you are actually planning. You send your florist an inspiration photo. The flower in it is out of season for your date. Here is what comes back instead — and whether it is a close call or a visible compromise.

What you asked for	Real window	What you will be offered	How close
Peony	~2 months (May–Jun)	Garden rose, double tulip, ranunculus	Shape close, scale smaller
Dahlia	~3 months (Aug–Oct)	Chrysanthemum, garden rose	Chrysanthemum reads close at distance
Tulip	~3 months (Feb–Apr)	Ranunculus, lisianthus	Different silhouette, similar softness
Ranunculus	~6 months (Mar–Aug)	Lisianthus, spray rose	Very close
Lily of the valley	~1 month (May)	Stephanotis, waxflower	Not close; scent is unreplaceable
Sweet pea	~3 months (Apr–Jun)	Lisianthus, spray rose	Form close, movement lost
Sunflower	~3 months (Jul–Sep)	Gerbera daisy, craspedia	Scale much smaller
Hydrangea	~6 months (Apr–Sep)	Imported hydrangea at a premium	Same flower, higher price

Read the right-hand column carefully. Some substitutions are genuinely invisible in photographs — a chrysanthemum standing in for a dahlia is a call most guests will never make. Others are not. If lily of the valley is in your inspiration photo and you are not marrying in May, the version you receive will be a different flower doing a different job.

Why the flowers you want are the ones you cannot have

There is an inverse relationship worth naming, because it explains almost every frustrating floral conversation.

The blooms that dominate wedding inspiration — peony, dahlia, ranunculus, tulip, lily of the valley, sweet pea — are seasonal precisely because they are the ones that do not tolerate industrial year-round production. Short windows, fragile stems, narrow growing conditions. That scarcity is part of why they read as special.

The flowers available every month are available because they are robust, ship well and grow under glass at scale. Robustness and romance are, unhelpfully, inversely correlated.

This is the mechanism behind what we have called the availability problem elsewhere — that the calendar quietly edits your colour choices before you ever get to choose. If you want to see how that plays out across a full palette rather than a single flower, the palette method works through it.

How to use this when you plan

Three practical moves fall out of the table.

Anchor on one seasonal flower, fill with year-round. Pick the month's best bloom as your focal flower and build the rest from the twelve-month list. This is what experienced florists do by default, and it is why arrangements from the same studio look coherent across different seasons.

Check your inspiration photo's month before you fall in love with it. Most inspiration images are undated. A bouquet photographed in June and a wedding held in November are two different projects.

Decide early whether the specific flower matters or the look does. If it is the shape and colour you want, substitution is fine and nobody will know. If it is that flower specifically — the peony your grandmother grew, the lily of the valley from your mother's bouquet — then the month is not negotiable and you should say so at the first conversation, not the last.

On timing generally, the ordering timeline covers how far ahead each decision needs to be locked.

Where artificial flowers change the calculation

One honest paragraph on this, because it is the obvious thing to say and it deserves to be said plainly rather than woven through the whole guide.

Artificial flowers have no season. A November peony bouquet and a May peony bouquet are the same product at the same price, because nothing was grown, flown or forced. That removes the substitution problem entirely for anyone whose date falls outside their flower's window — which, given that peonies occupy two months of twelve, is most people.

It does not remove every trade-off. Fresh flowers have scent and a particular translucency that reproduction still approaches rather than matches, and the quality range in artificial flowers is enormous — the difference is usually visible at the stem rather than the bloom, which the quality guide covers in detail. But on availability specifically, the calendar stops applying.

For what a complete set costs when season is not a variable, see the full-set receipt. For the two flowers this comes up with most, we have written about the peony's two-week window and why dahlias barely ship at all.

Common questions

What flowers are in season for a wedding in every month?

Roses, carnations, alstroemeria, baby's breath, lisianthus, orchids, calla lilies, gerbera daisies, freesia, stock, delphinium, iris, protea, scabiosa and veronica are available year-round. Availability is not the same as low price — roses are year-round and still expensive.

Can I have peonies at a November wedding?

Yes, through southern-hemisphere imports, at a premium. Whether that premium is worth it depends on whether you want peonies specifically or peony-shaped blooms. Garden roses and double tulips fill the same visual role for considerably less.

Which month has the fewest options?

January and December are the thinnest for garden flowers, which is why winter work leans on berries, branches, amaryllis and the year-round list. This is a constraint, not a defect — winter arrangements built around texture rather than bloom count photograph very well.

Does choosing in-season flowers actually save money?

Yes, for the same reason seasonal produce is cheaper: no import, no forcing, shorter supply chain. The size of the saving varies by flower and region, so ask your florist to price two versions of the same design rather than relying on a general rule.

How far ahead do I need to decide?

Far enough that your florist can source rather than substitute under pressure. Peak-season blooms in peak wedding months are the tightest — a September dahlia wedding booked in August is a different conversation than one booked in March.
