Dues cover full membership in, and the bulletins of, the American Dahlia Society (ADS), as well as copies of the Classification and Handbook of Dahlias. The Handbook of Dahlias is an invaluable source of information on about 2000 of the most grown dahlia varieties in North America.

New members will also receive Colorado Dahlia Society nametags which we encourage you to wear at any dahlia meeting, show or other dahlia gardening or horticultural event you may attend.

CDS members also receive:

  • A copy of our annual show book
  • All meeting announcements, minutes and other mailings
  • Access to CDS member-only events
  • Free Dahlia tubers!

CDS members are eligible to participate in our annual tuber roundup and free tuber exchange. The Colorado Dahlia Society meets monthly usually on the 2nd Sunday of most months from February thru October. All members are encouraged to attend and share in some of the best potluck luncheons in Northern Colorado.

And, yes there is still such a thing as a free lunch! All first time meeting attendees are invited to join us in enjoying a pre-meeting potluck luncheon. Just bring your own table service and eat hearty.

The CDS offers classes and discussions on Dahlia growing and showing as part of our monthly meetings. Mentoring is also available to answer your questions and help you grow the best Dahlias possible!
