Founded in 1922, the American Horticultural Society is one of America’s oldest and most respected horticultural organizations.
Headquartered at the historic River Farm estate along the Potomac River in Alexandria, Virginia—land once owned by George Washington—AHS occupies a unique position at the intersection of horticultural education, garden tourism, environmental advocacy, and community building.
Unlike organizations focused exclusively on home gardening or specific plant types, AHS takes a comprehensive approach to advancing horticulture in all its dimensions:
- Supporting public gardens
- Educating gardeners at all levels
- Recognizing horticultural achievement
- Promoting environmental stewardship
- Serving as a unifying force for America’s diverse gardening communities
