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:
