Founded in 1922, the non-profit American Horticultural Society (AHS) is one of the oldest member-based national gardening organizations in North America. The Society’s membership includes nearly 20,000 avid gardeners and horticultural professionals, as well as numerous regional and national partner organizations. Through its educational programs, awards, and publications, the AHS connects people to gardening, raises awareness of earth-friendly gardening practices, introduces children to plants, brings together leaders to address important national issues, and showcases the art and science of horticulture.
The AHS headquarters at River Farm in Alexandria, Virginia, is a national showcase for gardening and horticultural practices. Once part of George Washington’s farmland, this 25-acre historic site overlooking the Potomac River features a blend of formal and naturalistic gardens, including a four-acre meadow, a vegetable demonstration garden, and an award-winning children’s garden.
