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.
