Public & Demonstration Gardens

Public Gardens in the Washington DC Metropolitan Area

Public gardens are living examples of which plant performs well in the area. Many public gardens have a reference library, gift shop, web site, and gardening hotline. Usually, public gardens host seminars, workshops, classes, events, and plant sales. They may publish their own books on plants for the area or distribute free handouts. Some have staff horticulturists who can identify plants or answer questions. For a complete list of public gardens by state, check out Call for admission fees and times (not all are free).

Demonstration Gardens

Demonstration gardens are a great way to learn what works in our area and how to manage our local issues, such as deer. The gardens are open to the public, every day, from dawn to dusk, free. Each county that has a Master Gardener program usually has at least one demonstration garden, managed by the volunteer Master Gardeners. To find such a garden, call your local county Master Gardener program representative (your local extension agent) and ask if they manage a demonstration garden. Some have several to showcase various environmental conditions and some use the garden as a place to teach or host workshops.

The Master Gardeners of Northern Virginia (Arlington and Alexandria) have five demonstration gardens:

  • Glencarlyn Library Community Gardens, corner of S. Third and S. Kensington Streets, off Carlin Springs Road, Arlington
  • Simpson Park Gardens (E. Monroe Avenue at the end of Leslie Avenue, next to the YMCA in Alexandria
  • Organic Vegetable Garden, Potomac Overlook Regional Park, Marcy Road, Arlington
  • Rock Quarry Shade Garden, Bon Air Park on Wilson Boulevard and N. Lexington Street, Arlington
  • Sunny Garden, Bon Air Park, Arlington

The Prince William County Master Gardeners manage a very large “Teaching Garden” at St. Benedict Monastery, 9535 Linton Hall Road, Bristow, VA. Within this large garden are mini gardens to illustrate certain conditions or issues, such as a deer resistant garden, shade garden, vegetable garden, and pollinator garden.

The Loudoun County Master Gardeners have Ida Lee Park on Ida Lee Park Drive, Leesburg, VA; which they also use as a teaching garden.

The Montgomery County Master Gardeners have a demonstration garden at the Agriculture History Farm Park, 18410 Muncaster Road, Derwood, MD.

The Prince Georges County Master Gardeners are fortunate to use the Kitchen Garden at the Riversdale Gardens and House Museum, 4811 Riverdale Road, Riverdale Park, MD.

In addition some plant societies such as the National Capital Dahlia Society have demonstration gardens specific to their plant of interest. Contact the society directly to see if they have one. The National Capital Dahlia Society has the Nordahl Exhibition Garden for displaying dahlias at the Agricultural History Park in Derwood, MD.
