Our speaker roster for Saturday, September 24, will include several seminars on research and hybridizing areas as well as others of general interest. Dr. Hanu Pappu, from Washington State University, will present an update on dahlia viruses and his latest efforts on virus detection. He may offer some insight to our growers in this difficult area. Dr. Alex Harkess of Auburn University will discuss the dahlia genome, and will update us on the progress on this important topic. Bob Schroeder will summarize and discuss the update of The Guidelines for Judging Dahlias, as well as reviewing the updated score card for both Trial Garden and Seedling Bench dahlias.

We are also looking forward to an enlightening talk by Kristine Albrecht about creating new dahlias. Kristine’s book, Dahlia Breeding for the Farmer-Florist and the Home Gardener, focuses on her approach to creating great dahlias that benefit those growing exhibition dahlias as well as for those who grow for the cut flower trade. Eileen Colton, longtime freelance photographer and NCDS member, will discuss flower photography. Her work has been published in The New York Times, USA Today and Rolling Stone. Eileen also worked as court photographer at the U.S. Supreme Court.
