“There is actually a Greek legend telling the story of how they got their name. Asters were named after the Greek word for ‘star’. Because, when the Greek god, Astraea, was upset by how few stars there were in the sky she started to cry. And when her tears hit the ground, they turned into asters.”

September Wedding Flower FAQs
If you’ve just begun your search for September wedding flowers, we've got expert tips and advice for you, based on what's in season in September.
“There are many flowers in season in September, including Dahlias, sunflowers, asters, alstroemerias, roses, and many more,” says coveted florist Holly Briers at Floral Art Devon.
“I think towards the end of September it's lovely to go into the autumnal feel with flowers and colours, but also, it is the couples choice, and they may have already planned their theme and colours, so we always work with their bespoke theme and flower vision.”
“September is a brilliant month for flowers, where the bright, abundant flowers of summer haven’t yet faded, and the darker, deeper hues of autumn are starting to emerge,” says Gemma, owner and lead florist at Femme Petale.
“I love working with flowers that offer a lot of variety, coming in a multitude of colours to fit different couples’ colour palettes or the look and feel they are after."
We asked Milly from Flower & Farmer for her expert input on September wedding flowers:
What makes September such a special month for wedding flowers?
In short, the colours and the flower selection! September is a beautiful bridging month between summer and autumn. The colours are rich and romantic - think dusky pinks, burnt oranges, deep reds and burgundies.
British-grown flowers are also at their best right now, with dahlias, cosmos, scabious, sunflowers, calendula, zinnias, didiscus, Japanese anemones and pelargoniums all in peak season. Even roses get a second flush, making September a dream month for wedding florals.
Which flowers are in peak season in September?
Dahlias, cosmos, scabious, sunflowers, calendula, zinnias, didiscus, Japanese anemones, pelargoniums – and a second bloom of roses. It’s an abundant time for British-grown flowers.
How do September flowers differ from those in summer or late autumn weddings?
September flowers tend to lean into deeper, richer tones than summer blooms. The colour palette reflects what you see in gardens and hedgerows – bronze-tinged foliage, saturated petals, and moodier undertones. Spring brings delicate pastels, summer offers a wide range of soft hues, and September begins to deepen those tones as we edge into autumn.
What colour palettes work best for a September wedding?
White-based palettes still work beautifully – particularly with roses, dahlias, cosmos and Japanese anemones. But if you’re leaning into seasonality, bold and strong colour is where September really shines. Soft pastels are less available, so consider leaning into the richness of the season.
Are there any creative or sustainable ways to use September blooms in installations or bouquets?
Absolutely – and the key is hydration. British-grown flowers need a reliable water source to look their best. We use chicken wire in place of floral foam (which is a microplastic and harmful to the environment), and we always ground our installations in vessels filled with water. Keeping flowers happy and hydrated is the foundation of any successful design.
What are your favourite flowers to work with in September?
Dahlias! They’re bold, architectural and bring so much beauty to bouquets and arrangements. Total showstoppers.
Are there any lesser-known September flowers couples should consider?
Pelargonium foliage is a secret favourite. It’s highly scented and comes in a wide range of colours and shapes - from silvery greens to burgundy tones. It adds unexpected depth, movement and fragrance to bouquets, and really elevates the overall feel.
