The first winter, half our dahlia tubers died. Dahlias had always fascinated me, with their vibrant flowers ranging from tiny blooms to enormous specimens the size of soccer balls. When Bryan and I first had our own garden, we decided to grow these bizarre and beautiful blooms. Like most things, that turned out to be more difficult than expected.
Thankfully, the largest dahlia farm in the country sits just 35 minutes from Portland. Every August and September, Swan Island Dahlias opens their spectacular dahlia fields Oregon to the public for a free festival of flowers, complete with dahlia-growing classes that could have saved me from that first-year tuber disaster.
Why Swan Island Dahlia Festival is Oregon’s Premier Flower Experience
Swan Island Dahlia Festival transforms Canby, Oregon into the Pacific Northwest’s flower tourism capital. This isn’t just about pretty blooms – it’s about experiencing the largest dahlia operation in America, where visitors can learn from experts who’ve perfected the art of growing these challenging yet rewarding flowers.
What Makes Swan Island Special
We bought our original dahlia tubers from Swan Island Dahlias, so visiting the Oregon dahlia festival feels like returning to the dahlia Mother Ship. Walking among rows and rows of luminous, delightfully unique blooms creates an aura of beauty and inspiration that I try to carry back to our home garden.
The diversity overwhelms visitors in the best possible way. From tiny pom-pom varieties to dinner-plate dahlias larger than your head, every color combination and flower form imaginable spreads across these Oregon flower fields.

Learning from the Dahlia Experts: Why Growing Dahlias is Challenging
Visiting Swan Island dahlia fields provides crucial education for home gardeners struggling with these temperamental beauties. My own dahlia journey illustrates why expert guidance matters.
The Slug Battle: Year One Challenges
When we first planted dahlia tubers, every slug in the neighborhood descended on the young shoots, possibly before they even broke soil surface. Many slug pellets later, we managed to grow several plants to maturity. Our little clump of flowering dahlias felt like a great victory.
Then winter arrived with its storage challenges.
Winter Storage: The Make-or-Break Moment
The internet advised digging up tubers for winter, packing them with damp coconut coir or peat moss to prevent shriveling. The moisture level proved critical – too damp and tubers rot, too dry and they shrivel.
Storage temperature mattered equally: cold enough to remain dormant, but not freezing. Labeling became essential once all tubers went into storage boxes together.
Learning from Failure
That first year, I diligently dug up tubers, rinsed and labeled them, packed them in the basement, and spritzed them slightly. Spring revealed my over-correction – most formerly plump tubers were now sunken and shriveled. I’d avoided rotting but hadn’t kept them damp enough.
Finding Success: Pacific Northwest Solutions
The second year, I discovered an alternative approach better suited to our mild Pacific Northwest climate. Instead of digging tubers, cover the planting area with plastic (preventing excess water in our rainy region) and mulch heavily (preventing freezing).
This Oregon dahlia growing method proved much more successful. Instead of losing half our tubers, we lost only one in year two. Progress!
Oregon’s Flower Tourism Beyond Dahlias
Oregon flower fields extend far beyond dahlias, creating year-round flower tourism opportunities throughout the state.
