A century of dahlias

Since 1927

A family farm rooted in Oregon soil and devoted to growing the most extraordinary dahlias in the world.

For nearly 100 years, Swan Island Dahlias has cultivated beauty, tradition, and innovation from the rich farmland of the Willamette Valley. Today, we are proud to be the largest dahlia grower in the United States and a destination for flower lovers from around the world.

Every bloom we grow carries a story of family, land, and generations devoted to the art of the dahlia.

Where It All Began

1927 Portland, Oregon

Swan Island Dahlias was founded in 1927 by Frances McCarter, later McDuffee, and her husband. Originally known as Rex Dahlia Gardens, the business began in Portland, Oregon, with farming in the Sellwood district and offices and warehouses near Swan Island.

The name changed over the years, first to Portland Dahlia Garden in 1934, and then to Swan Island Dahlias in 1948.

In the 1940s, the farm moved to Canby, Oregon, where the rich, sandy soil of the Willamette Valley proved ideal for growing exceptional dahlias.

Today, the farm spans nearly 50 acres and continues to grow in the same community we’ve called home for generations.

Family Legacy

The Gitts Family

In 1963, Nick and Margaret Gitts purchased Swan Island Dahlias and moved their family of seven from Washington to Oregon. They had previously owned a dairy farm and a small dahlia business called Laurel Valley Dahlias, but Swan Island brought a new opportunity: 20 acres of dahlias, plus a growing retail, mail-order, and wholesale business.

Under the Gitts family, the farm continued to grow, eventually expanding to nearly 50 acres. Nick and Margaret’s sons, Nicholas and Ted, joined the business in the 1970s and later purchased the farm as their parents retired.

Today, Swan Island Dahlias remains family-owned and operated. Nicholas Gitts continues to lead the farm, while his daughter, Heather Gitts-Schloe, manages the office, website, and day-to-day business. The farm is now carried forward by the second and third generations of the Gitts family, with deep pride in its history and great care for its future.

More Than a Flower

The Art of the Dahlia

Dahlias are among the most expressive flowers in the garden, and growing them is both a science and an art.

At Swan Island Dahlias, we grow more than 375 varieties across nearly 50 acres, carefully cultivating each plant for beauty, strength, and quality. Our family has spent generations selecting, growing, and introducing dahlias in remarkable shapes, sizes, and colors.

Some varieties become longtime favorites. Others are brand new introductions.

Every one begins in the soil of this farm.

Our mission

To grow extraordinary dahlias and share their beauty with gardeners around the world.

We are proud of the farming tradition our family brings to Swan Island Dahlias. As stewards of a nearly century-old business, we remain dedicated to growing the highest-quality dahlias now and for future generations.
