What Blooms Are in Season for My Wedding Day? | September Edition

If you’re planning a September wedding, you’re in luck. This golden month marks the gentle handover from late summer into early autumn—a moment where gardens brim with abundance, texture and rich, romantic colour. For couples drawn to a natural, garden-gathered floral style, September offers a treasure trove of British-grown blooms that balance softness and structure beautifully.

At Rutland Florals, our designs are deeply rooted in the rhythm of the seasons. As professional gardeners (and DIY brides ourselves), we know there’s something incredibly grounding—and beautiful—about choosing flowers that are at their best on your wedding day. It’s not only a more sustainable way to flower your day; it also ensures your florals feel as authentic and effortless as the love you’re celebrating.

So, if you’re wondering what flowers are in season for a September wedding?, here’s what’s typically blooming—and why we love designing with them.

⸻

1. Dahlias – The Stars of September

Dahlias are, without doubt, the headliners of early autumn. Available in a dazzling variety of shapes, sizes, and colours—from rich burgundy and coral to soft blush, peach and ivory—they bring serious impact to bouquets and arrangements alike.

We love using dahlias for bridal bouquets because they offer drama and delicacy. Their sculptural form makes them a natural focal flower, and their colour range means there’s something for every palette, whether you’re leaning towards earthy warmth or soft romance.

✨ Florist tip: Café au Lait is always a favourite with our couples. It’s big, soft, and perfect for a romantic look—but there are so many other beautiful varieties that may better suit your individual palette and mood.

2. Garden Roses – Timeless, Fragrant, and Full of Petals

While imported roses are available year-round, British-grown garden roses often have their last hurrah in early September. Think ruffled petals, delicate scents and a more relaxed feel than their commercial cousins.

They’re ideal for adding a touch of elegance and softness, especially when paired with more structured flowers like dahlias or zinnias. For couples who want a bouquet that feels like it was picked fresh from the garden, this is one of our go-to ingredients.

3. Zinnias – For a Pop of Colour and Cheer

Zinnias are perhaps less well known, but we adore them for their cheerful shapes and vivid hues. Think coral, raspberry, and soft apricot—perfect for couples leaning into a more playful, modern palette.

Locally grown zinnias tend to be smaller and more refined than their supermarket counterparts, making them lovely accents in table arrangements, buttonholes, and flower crowns.

4. Cosmos – Delicate and Dreamy

Cosmos are quintessentially gardeny—light, fluttery, and ethereal. With their daisy-like faces and feather-light foliage, they add texture and softness to bouquets.

In September, you’ll find cosmos in gentle whites, pinks, and even deep plum, depending on the variety. They pair beautifully with heavier blooms like dahlias, giving your floral arrangements a sense of lightness and movement.

5. Scabious – Texture and Whimsy

Scabious (or pincushion flower) is a beautiful addition to any September bouquet. Available in shades of plum, dusty lavender, blush and cream, their unique shape adds an element of the unexpected without ever looking out of place.

The seed heads that follow the blooms are also a dream to work with—especially for a slightly more naturalistic or woodland-inspired look.

⸻

6. Hydrangea – Fading Beauty in the Best Way

By September, many hydrangeas begin to ‘antique’—softening in colour and developing lovely, vintagey tones of dusky green, rose, and blue. We often use these in larger installations (like arches or mantels) to bring structure and fullness.

They’re perfect for couples who want their flowers to feel both romantic and a touch wild.

7. Herbs, Grasses & Foliage – The Finishing Touches

No Rutland Florals design is complete without thoughtfully chosen foliage. In September, we’re often foraging for seed heads, grasses, and aromatic herbs like rosemary and mint to add texture and scent.

This is where the seasonal magic really comes alive. These elements tie your florals to the time of year, grounding them in the landscape and giving your wedding flowers a sense of place.

So, what does this mean for your September wedding flowers?

Whether you’re drawn to the warm tones of autumn or still holding onto the last blush of summer, September gives you the best of both worlds. It’s a month of abundance, and with the right florist (hello!) you can make the most of it.

Choosing flowers that are in season isn’t about compromise—it’s about leaning into beauty that feels authentic and effortless. When your bouquet is filled with blooms that are thriving in the garden that very week, there’s a kind of magic that just can’t be replicated by something flown halfway across the world.
