Key Points
- Summer wedding flowers in Westchester are at their most generous from late June through September — dahlias, zinnias, cosmos, garden roses, and hydrangea are all in season.
- Peonies and flowering branches are spring-only. If your heart is set on peonies, a June-or-later wedding will most likely miss them — so choose your date around the flower, not the other way around.
- Dahlias peak in late summer and early fall. The closer you get to September, the bigger and more abundant they are — some the size of a dinner plate.
- Hydrangea is available nearly year-round, which makes it the reliable backbone almost any summer palette can be built on.
- Bottom line: bring your date and your must-have flowers to The Flower Bar early. Some blooms are worth planning your wedding date around.
What's Actually in Season for a Summer Wedding in Westchester
If you're planning a summer wedding in Westchester, the honest answer is that you've picked one of the easiest seasons to work with — as long as you know which flowers actually belong to it. From late June through September, the local fields and gardens give us dahlias, zinnias, cosmos, garden roses, and hydrangea, which means your summer wedding flowers can feel fuller, looser, and more alive than almost any other time of year. It's the stretch of the calendar our wedding team most looks forward to designing for.
The one thing we tell every couple first: flowers have seasons, and the calendar doesn't bend for us. The most important decision you'll make about your flowers often isn't the color or the shape — it's the date.
The One Rule That Changes Everything: Choose the Date to Match the Flower
Here's the rule we come back to in every wedding consultation. If there's a specific flower you cannot imagine your day without, we plan the date around it — not the flower around the date. In Nancy's words: "Choose a date that will allow us to provide those flowers."
The two flowers this matters most for in summer:
- Peonies are spring flowers. Their season is short and it's over well before most summer weddings. A June wedding is already cutting it close, and by July the peony window has closed. If peonies are the flower you've been dreaming of, that's a real conversation to have before you lock a date.
- Flowering branches — the tall, blossoming branches that give a ceremony that orchard-in-bloom feeling — are also a spring story, not a summer one.
And the reassuring counterweight: hydrangea is available nearly year-round. If you want a lush, full look with dependable volume no matter your date, hydrangea is almost always there for us — which is exactly why it anchors so many summer arrangements.
Summer's Local Stars: The Flowers at Their Peak
Summer is when the best selection of locally grown flowers finally arrives, and it changes everything about how an arrangement feels. These are the blooms we reach for from late June onward.
Dahlias
Dahlias are the flower Nancy most looks forward to all year. They come into their own in late summer and early fall — the closer to September, the more spectacular they get. According to Cornell's cut flower research, dahlias in our region bloom from roughly the first week of July until the first hard frost, with their heaviest, showiest flush in late summer. That's why a late-August or September wedding can have dahlias the size, literally, of a dinner plate. Nancy harvests her own zinnias and dahlias from her garden at dawn when the season is on.
If dahlias are your must-have, aim your date at the back half of summer.
Zinnias, Cosmos, and the Field-Grown Supporting Cast
Every arrangement has a star with a supporting cast — and in summer, the supporting cast is where the magic really lives. This is the season for zinnias, cosmos, Queen Anne's lace, gladiolas, larkspur, Japanese anemone, and sweet pea. These are the airy, garden-grown flowers that make a bouquet look like it was gathered rather than assembled — a looser, garden style with layers of flowers, the kind that feel grown, not arranged.
They're also what makes summer weddings feel like summer: soft, unstructured, full of movement.
Green-Center Sunflowers
Sunflowers are a summer signature, but we're particular about them. We use the green-center varieties, and only when they're local and in season. They read fresher and more refined than the big dark-centered supermarket sunflower, and they fold beautifully into a late-summer palette without tipping into anything too rustic.
Garden Roses
Garden roses are the heart of most of the wedding work we do. Ours come from Alexandra Farms in Colombia — the growers behind the Juliet and other cupped, high-petal-count varieties that give a bouquet that romantic, old-world density.
There's a reason they smell the way they do. As Nancy explains it: "Standard roses have been bred for long, strong stems, which means having a scent is sacrificed. Garden roses are fragrant… determined by their high petal count." For a wedding, that fragrance is part of the memory.
Where Your Summer Wedding Flowers Come From
The sourcing behind the season is the part most people never see — and it's the part we care about most. In summer, a real share of what goes into your flowers is grown a short drive away: at Bloom Court Farm in Chappaqua, at regional grower co-ops, and in Nancy's own garden. Choosing flowers that are in season and locally grown isn't just a nice story — the Association of Specialty Cut Flower Growers, the trade group for American flower farmers, exists to champion exactly that: fresher flowers, cut closer to when you'll actually use them.
Nancy's Pro Tip: Some of the most beautiful roses Nancy sees all year are grown locally in summer — but they have a short vase life, so she buys them for weddings specifically. A wedding flower only has to be perfect for one day, which means a locally grown rose that would fade too fast in a week-long arrangement can be exactly right for a bride. It's one of the quiet advantages of getting married in the season these flowers actually grow.
Planning Your Summer Wedding Flowers with The Flower Bar
A summer wedding gives us the richest palette of the year to work with, but the flowers still have to be planned for. Here's how our wedding team likes to approach it with couples.
Start with the date and the venue, then the flowers. Once we know when and where, we can tell you honestly what will be at its peak and what won't — and where we'd guide you toward a summer flower that will be more beautiful than an out-of-season stand-in.
It's the small, unexpected touches that people remember. At the sweetheart table, we always tuck a small bloom onto each napkin — something unexpected. Little moments like that are where a summer palette gets to show off.
You won't be chasing us. We give our wedding and event couples our cell phone number so we're reachable at any time. A wedding is not the time to wonder whether your florist got your email.
When you're ready, our weddings and events team will walk you through your date, your palette, and what summer is actually giving us that year. You can also browse our wedding flower collection to start gathering the looks you love, and if you're still choosing who to work with, our guide on choosing a wedding florist in Westchester County is a good place to begin.
Planning a Summer Wedding in Westchester
Summer is the season the local fields do the heavy lifting — dahlias, zinnias, cosmos, garden roses, and dependable hydrangea, most of it grown close to home.

The Flower Bar is rooted in Larchmont and designs weddings across Westchester, Fairfield County, and NYC, and we'd love to help you build a summer palette that feels grown, not arranged. Tell us your date and the flowers you've been dreaming about — we'll take it from there.

Frequently Asked Questions
What flowers are in season for a summer wedding in Westchester?
From late June through September, summer wedding flowers at their peak include dahlias, zinnias, cosmos, Queen Anne's lace, gladiolas, larkspur, sweet pea, green-center sunflowers, and garden roses, with hydrangea available nearly year-round as a full, dependable base. This is the season of locally grown flowers in Westchester, so arrangements tend to feel looser and more garden-gathered than at any other time of year.
Can I have peonies at my summer wedding?
Most likely not. Peonies are a spring flower with a short season that's usually over by early-to-mid June, so a summer wedding will typically miss them. If peonies are a must-have, the honest advice is to choose a spring date around them. For a summer date, garden roses give you a similar full, romantic, high-petal look that's actually in season.
When are dahlias in season for a Westchester wedding?
Dahlias hit their stride in late summer and early fall. In our region they bloom from about early July until the first hard frost, with their biggest, most abundant flush in late August and September. If you want dahlias — especially the dramatic dinner-plate size — aim for a late-summer or early-fall date.
Are hydrangeas available all summer?
Yes. Hydrangea is one of the most dependable flowers we work with and is available nearly year-round, which makes it a reliable backbone for summer wedding arrangements when you want lush volume regardless of your exact date.
