North American Dahlia Society

We Love Dahlias!

The 2017 National Show was a great success!

Congratulations to all the participants and the winners.
Also, congratulations and thanks to the Central States Society
for hosting the show.  Great job!!
Summary of the Show
Pictures and video coming soon.


Without the tireless efforts on the part of local society and conference members, ADS National Shows would not be the successful events we have come to expect. At the 2017 National Show, the American Dahlia Society extended its appreciation to four members of the hosting Central States Dahlia Society who contributed much to the success of this occasion.

Fred Brill was instrumental in much of the show planning and detail work, including the transformation of the 2017 show logo into a workable graphic that became a key identifier of the show.

Jim Kassner served as Show Co-Chair and an important contribution on his part, was coordinating with the staff at Chicago Botanic Garden on the arrangement of the show exhibition halls. A distinct and pleasing visual effect was created by the resourceful placement of exhibition tables. Of course, having the correct number of tables for a National show is a big issue and how many to rent, if necessary, is an important consideration.

Charlene Meyers brought the show to life through her work as CSDS website director. This was a special effort which put a welcoming face on the event even before it began.

Finally, George Koons developed a publicity plan that carried through the entire event. George collaborated with the ADS Bulletin, the ADS and CSDS websites, and local media to serve notice, in a very spectacular way, that the American Dahlia Society’s 51st National Show would be held in Chicago, and that it would be an event dahlia lovers would not want to miss!

The ADS congratulates all who made the 2017 National Show an enjoyable and memorable experience.

Genome Project Update

The American Dahlia Society (ADS) is currently working to sequence the dahlia genome. ADS is funding the DNA sequencing of the dahlia. This process determines the complete set of genes or genetic material in a cell or organism. In January 2017 the ADS donors met our first goal of $30,000 for the project.  To date we have raised $37,000 from 50 donors from 17 states and Canada.  With these funds, ADS will be sequencing 6 species dahlias and dahlia Edna C plus one more modern dahlia. 

Dr. Walbot had two successful trips in October 2017 to collect species dahlia seeds in Mexico. It’s looking like she will have 12-13 species to choose from for the genome project. Currently, she is leaning towards towards the high quality genome sequencing using D.sorensenii. Originally she was thinking she would sequence D. coccinia in depth but it has wide variation in flower color, leaf shape, leaf size and stem properties. ADS has funds to sequence 6 species dahlias and two modern day dahlias. Sequencing is expected to be complete in March or April. 

In early October, Dr. Pappu heard back from the National Science Foundation that our grant proposal wasn’t funded.  Dr. Walbot, Dr. Saar, and Dr. Pappu will consider resubmitting the grant which is typically done taking into account the critiques of the grant readers.
