Our Gardens

River Farm is a historic 25-acre site that was once part of George Washington’s original five farms and has been the headquarters of the American Horticultural Society since 1973.

America’s Garden Showcase

A short drive along the scenic George Washington Parkway from Alexandria, Virginia, River Farm is acclaimed for its spell-binding vistas stretching down to the Potomac River, along with its creative children’s gardens, beautiful four-acre meadow, and colorful flower displays. It is a favorite site for weddings, family picnics, bird-watchers, and painters.

Clara B. Plein Memorial Garden

This garden features 68% native plants and 32% native cultivars, arranged in a classic Virginia landscape setting. The emphasis on native plantings demonstrates how traditional horticulture can incorporate environmental best practices, which in turn support our local ecosystems.

Perennial Borders 

A series of smaller gardens offers an ever-changing succession of color and interest throughout the year. Plants in each section of the garden are coordinated by color, season of bloom, size, and texture. They have also been selected for resistance to diseases and pests.

White House Gates 

At one end of the Perennial Border stands a set of historic White House Gates. These gates were first installed at the White House in 1819, as part of the reconstruction project to repair damage from the War of 1812. They stood for more than 120 years at the northeast entrance to the White House before being removed during a renovation project. The gates found a second home on the River Farm property and remained in relative obscurity for more than 50 years. In 2004, the Society undertook restoration and conservation of the gates to return them to their original splendor.

Manor House 

River Farm’s manor house is home to the Society’s Administrative and Membership offices. The lower floor is open to the public and features a charming parlor with a stunning river view, and a beautiful ballroom. Rotating exhibits by area artists are often on display in these rooms. The manor house is a popular venue for weddings, corporate events, meetings, and memorials, and is available for rental.

The plantings in front of the manor house consist predominantly of native shrubs and trees, including Allegheny serviceberry (Amelanchier laevis), fringe tree (Chionanthus virginicus), dwarf fothergilla (Fothergilla gardenii), and oakleaf hydrangea (Hydrangea quercifolia). An underplanting of mixed perennials and annuals provides seasonal color, and is especially eye-catching in spring when thousands of bulbs are in bloom.

The bluestone terrace beside the manor house is framed on one side by a stately hedge of English boxwood (Buxus sempervirens ‘Suffruticosa’) containing specimens nearly 100 years old. Perennial and annual display beds behind the manor house provide seasonal color and interest.

Ha-Ha Wall 

A sunken brick Ha-Ha Wall borders the western side of the meadow area. In England, these walls were introduced in the 18th century to keep livestock and wildlife out of manor gardens without erecting a noticeable fence to spoil the view..

Children’s Garden 

River Farm’s popular Children’s Garden, initially developed by school groups and professional landscape designers, is made up of more than a dozen, small, themed gardens designed to stimulate children’s interest in plants and nature. With the help of many volunteers and a dedicated staff, these gardens delight the child in all of us.

The Garden Calm 

The Garden Calm is planted with shrubs, trees, and perennials that prefer full or part shade. The large tree that provides most of the shade for this area is an Osage orange (Maclura pomifera). This particular tree is estimated to be 200 years old.
