The Perennial Garden Club enjoys a rich history of community partnerships. These include collaborative ventures such as the first Club civic garden project developed in 1951 at the Washington City Orphan Asylum.
Perennial produced many landscaping projects in the District of Columbia including Decatur House, a National Trust Property, and from 1971-73,
the entrance garden of Blair House, the official guest quarters for State visitors to the United States.
In 1998, Perennial received the GCA Zone VI Historic Preservation Award for restoration of the gardens at the historic Woodrow Wilson House. Additional collaborative projects include therapeutic gardens at the National Rehabilitation Hospital and nine Habitat for Humanity gardens.
Perennial Garden Club developed an urban educational landscape project at the Bishop John T. Walker School for Boys (BWS) in Washington DC, receiving the GCA's prestigious Founders' Fund Award in 2012. Perennial and its members
continue to support garden-centric educational projects with the BWS.
Perennial also lends support in the form of grants and contributions to ongoing community projects with the Friends of the National Arboretum and the Washington Youth Garden, the U.S. Botanical Garden, and Building Bridges Across the River and the GCA's Scholarship Fund.
