Every florist has a flower they get a little insufferable about once a year, and for us it is dahlias, and it is right now. Late summer is dahlia season in the Willamette Valley, and the epicenter of it all is not some far-flung destination — it is a working farm about half an hour south of Tigard, in Canby. If you have ever wondered where all these impossibly perfect dinnerplate blooms actually come from, this is your answer, and it is worth the drive.
We are talking about Swan Island Dahlias, and if you have never been, late August through the first frost is exactly the window to go.
🚜 A Family Farm, Not a Corporate Attraction
Swan Island Dahlias has been a family operation since 1963, when Nick and Margaret Gitts bought the farm and moved their family down from Washington. What started as around 20 acres grew, over decades, into nearly 50 acres of dahlias — and it is still family-run today, now carried forward by the second and third generations of the Gitts family. That kind of multi-generation continuity is rare in any industry, and it shows in how the place is run: this is a real working farm, not a manicured tourist attraction, and that is exactly the appeal.
🚗 Getting There From Tigard
The drive is easy: south on I-5 through Wilsonville, then east toward Canby. It is close enough to be a half-day trip and far enough to feel like you actually went somewhere — the kind of outing that pairs nicely with everything we said in our guide to Tigard’s trails about getting out and seeing what is actually blooming around here instead of just reading about it.
While you are in the area, the tiny historic district of Aurora is just down the road — a cluster of antique shops worth a wander if you want to turn the trip into a proper afternoon rather than a quick errand.
🌼 What You Will Actually See
Rows and rows of dahlias, in every form the flower comes in — dinnerplates the size of a salad plate, tight little pompons, spiky cactus types, and waterlily forms that look like they belong in a pond instead of a field. The color range is the real showstopper: everything from blush pastels to colors so deep and saturated they look almost black. Fields are open to walk through during the season, typically daylight hours, and the farm also holds a dahlia festival most years over a late-August weekend — check their site for the exact date before you go, since it shifts a bit year to year.
The farm sells fresh-cut stems and bouquets on site during the season, and ships dahlia tubers for home gardeners every spring. If you have ever thought about growing your own, late summer — while the plants are in full bloom in front of you — is the best possible time to decide which varieties you actually want in your own backyard next year.
🏵️ Why Your Florist Gets This Excited
Dahlias are genuinely one of the trickiest cut flowers to work with — gorgeous, but short-lived compared to a rose or a carnation, and they demand the right conditioning to hold up in a vase at all. We wrote the full breakdown of forms, care, and vase-life tricks in our complete guide to dahlias, and it is worth a read before you bring any home, whether you cut them yourself in Canby or pick up an arrangement from us.
The short vase life is exactly why local matters so much with this flower. A dahlia that traveled 30 minutes from a Canby field to your table this morning behaves completely differently than one that spent days in transit. That is the whole case for a farm this close: freshness you simply cannot get any other way.
📆 When to Go
Peak bloom generally runs from mid-August through late September, tapering off as the first frost approaches. A weekday morning is your best bet if you want to avoid festival-weekend crowds and get the fields mostly to yourself. Bring a hat, bring cash for anything you want to buy on site, and bring a little patience — you will want to walk every single row.
Cannot make the drive this week? That is exactly what we are here for. Dahlia season is in full swing at the shop too, and we would love nothing more than to put a fistful of Canby-grown color on your table without you having to leave Tigard.
