The National Capital Dahlia Society Annual Show scheduled for September 25-27, 2015 will be held at the Derwood Agricultural History Park. 


An extensive renovation project at Brookside Gardens has fallen behind schedule and suitable access and parking will not be available.


The Montgomery County Agricultural History Farm Park has been the site of the NCDS Nordahl Exhibition Dahlia Garden, and the Mid-Summer Shows.   It is located at 18400 Muncaster Rd , Derwood MD 20855 and can easily be reached from the Beltway  or I-270.

Directions will be in the Dahliagram and on the NCDS website


Because it has been necessary to change our show site, we will need extra help with set-up and take-down.  More to come in the Dahliagram for September.


The National Capital Dahlia Society was established more than 75 years ago by a group of gardeners in the Washington, DC area to share their pleasure in growing and exhibiting dahlias, a flower of spectacular beauty and boundless diversity.

The NCDS holds monthly meetings to "talk dahlias," exchange plants and tubers and prepare for two annual shows that provide opportunities to engage in gentle competition and to display dahlia blooms to the public. The Midsummer Show is held in August at the Montgomery County, MD  Agricultural History Park in Derwood MD. The Fall  Dahlia Show, attracting blooms from throughout the Eastern States, will be hosted in 2014 at St Andrews Church in Arlington VA.

An Exhibition Garden for displaying outstanding dahlia varieties  is also located at the Agricultural History Park.   More than 100 dahlia plants are set out in May and bloom from August til frost.

More information about the dates, locations and times of NCDS events are located on this Website and in the Dahliagram newsletter, which is published for NCDS members 11 times a years.

All NCDS events are open to the public.  Membership information is available by clicking the "membership info" tab in the left margin
