The flowers on your tables will be cut within a day or two of your wedding. Where they came from, and whether they were grown in their natural season, shapes almost everything about them: their scent, how long they hold, how they sit in an arrangement, and what they cost. Choosing seasonally is not a constraint. It is the thing that makes flowers feel like flowers rather than a product.
What follows is a working guide to what is genuinely available at each point in the year, what is being brought in from elsewhere, and what that distinction means in practice.
Spring: March, April, May
Spring is one of the strongest seasons for wedding flowers, which is part of why it is so popular for weddings. The range is broad and the quality is high. Peonies are the flower couples ask for most often, and they arrive properly in late spring, from around mid-May. Before that point, any peony you are quoted will have been flown in, usually at a meaningful premium and without the scent that makes a grown peony worth having.
What is genuinely at its best in spring: tulips in every form, from simple single-colour stems to parrot and fringed varieties; ranunculus, which have a papery layering that photographs well and holds better than their delicate appearance suggests; sweet peas, which are one of the few flowers with a real scent at this time of year; anemones, with their dark centres and strong colour; and branches of blossom, which work well in taller arrangements and ceremony arches. Lily of the valley is a spring flower with a strong traditional association and an extraordinary scent, though it is expensive for what it gives in volume.
Foliage in spring tends to be soft and light-green, which suits arrangements that feel fresh rather than structured. If you want something more architectural, your florist will need to supplement with foliage that holds its form, since spring growth is often too tender to give much structure on its own.
Summer: June, July, August
The summer months give florists the broadest palette of the year. The question is less what is available and more what combination of colours and textures you are drawn to, because most things are genuinely in season at once.
Roses are at their peak and most abundant in summer, particularly in June and July. Garden roses, which have a looser, more layered head than the standard florist's rose, are in season now and have a quality that is difficult to replicate out of season. Sweet Williams, larkspur, foxgloves, cornflowers, scabious, and cosmos are all at their best. Dahlias begin in late summer, from around August, and their season runs into autumn. They are among the most useful flowers a florist works with: they come in an enormous range of forms and colours, they hold well, and they have enough substance to anchor an arrangement.
The only practical consideration in high summer is heat. Flowers cut in warm weather need careful handling and cool storage, and outdoor ceremonies in direct sun will shorten how long arrangements stay fresh. Your florist will know this and plan accordingly, but it is worth discussing if your ceremony or reception is largely outdoors.
Autumn: September, October, November
Autumn has the most distinctive character of any season for flowers, and it is also the season where the gap between what grows locally and what gets imported is easiest to see. The palette shifts: the soft pinks and whites of spring and the brights of summer give way to something richer and more amber. Dahlias continue strongly through September and into October, and the range available in autumn includes some of the darkest and most dramatic varieties. Chrysanthemums, which have had an unfair reputation for decades, are genuinely excellent cut flowers with a long vase life. Zinnias, rudbeckia, and amaranth are all in season.
Foliage becomes one of the more powerful elements of an autumn arrangement. Turning leaves, seed heads, berries, and grasses all add texture and colour that no summer arrangement can match. Many couples planning autumn weddings build the foliage and structural elements as the starting point and add flowers around them, which reverses the usual approach and often produces more interesting results.
By November the range narrows noticeably. This is the point at which a florist working with seasonal material will have a shorter list to offer, and where out-of-season flowers begin to make up a larger proportion of what is available in the wholesale market.
Winter: December, January, February
Winter is the season that relies most heavily on imported flowers, and understanding that honestly changes how to approach it. The flowers that hold up well in cold weather and travel long distances without losing quality, roses and carnations particularly, are the backbone of winter floristry, and they are not inferior choices. A well-chosen carnation in winter is a better flower than a tired peony flown in the wrong season.
What is genuinely in season in winter: hellebores, which have a downward-facing quality that suits arrangements where the eye is drawn to detail rather than mass; paperwhite narcissi, which are strongly scented; holly, ivy, and evergreen foliage, which give structure and last well; and branches of bare or budding stems, which work in tall arrangements and give a spare, architectural quality that suits winter light.
Winter arrangements tend to work best when the florist leans into what the season offers rather than trying to approximate another season with imported material. A winter wedding that uses hellebores, anemones, white tulips, and dark foliage looks like a winter wedding, which is to say it looks considered and deliberate. One built around peonies and garden roses in December tends to look slightly unconvinced of itself, and it will cost considerably more for that effect.
What happens when you choose out of season
A peony brought in from the other side of the world in November is not a bad flower. It is a flower that has been picked earlier than it would be naturally, chilled for the duration of its journey, and sold at a premium that reflects the logistics of getting it to you. It will look like a peony. It is unlikely to smell like one. It may open faster or slower than expected, depending on the conditions in transit, which makes it harder for your florist to guarantee that it will be exactly right on the day.
None of this means you cannot have the flowers you want. It means being honest with yourself and your florist about the trade-offs. The couples who end up disappointed are usually the ones who chose flowers for their appearance in a photograph taken in a different month, without discussing what those flowers will actually be like on their wedding day.
How seasonality changes what a florist can do
A florist working with seasonal material is working with flowers at their strongest: freshest, most fragrant, and most reliably consistent from stem to stem. That consistency matters more than it sounds. When a flower is in season, the florist can source it from multiple places, compare quality, and substitute without drama if one batch is not right. When a flower is out of season, it typically comes from one or two sources, and substitution mid-order is harder.
Seasonal choices also tend to give a florist more creative latitude. When they are not compensating for the limitations of out-of-season material, they can focus on form, proportion, and how the arrangement works as a whole. The best florists will tell you this themselves, and many will have a quiet preference for couples who let the season lead rather than arriving with a fixed list of flowers that happen to be at their worst in the month they are getting married.
The practical starting point is to tell your florist your wedding month and ask what is genuinely at its best then, before you mention the flowers you have been saving to a board. The answer will give you a real picture of what your arrangements can be, rather than a compromise built around what you asked for before you had the information.
