GCA club members are as varied in their talents and achievements as the organization itself. At the local level, nearly 18,000 individuals contribute a wealth of energy and expertise to the projects and activities of the Garden Club of America's 200 member clubs. Members from across the country also serve on more than 40 national-level committees, each of which plays a specific role in furthering the Garden Club of America's purpose:
to stimulate the knowledge and love of gardening; to share the advantages of association by means of educational meetings, conferences, correspondence, and publications; and to restore, improve, and protect the quality of the environment through educational programs and action in the fields of conservation and civic improvement.
"What We Do" describes efforts with an educational focus, in which committees share information, experience, and expertise among the GCA membership and the public at large.
