The Portland Dahlia Trial Garden is  located at Swan Island Dahlias in Canby, Oregon.  It is next to the Swan Island
show garden and is only a hundred feet or so from the parking lot.  There are about 30 new varieties of dahlias
entered each year from breeders around the USA and sometimes from overseas. The varieties are rated for show
potential. The garden is maintained by volunteers from our society.  The first trial garden director was the late Bill
Mishler. He was instrumental in founding the trial garden and guiding it through the many years of success. The
current trial garden director is Teresa Bergman of Cowlitz River Dahlias. Location of the trial garden
