Dumbarton Oaks: Washington, DC’s Top Spring Destination

Spring garden at Dumbarton Oaks

When we locals look to get away from it all, many of us head to a garden property known as Dumbarton Oaks. And this May, I had the pleasure of taking a private tour of the estate. It was an opportune time, not only for appreciating the spectacular flowers from behind the scenes, so to speak, but also for the magnificent spring weather .

ABOUT DUMBARTON OAKS

Located in the Georgetown neighborhood of Washington, DC, Dumbarton Oaks is an historic property. Featuring a grand, 19th century house and gardens of world-class distinction, it is the legacy of Ambassador Robert and Mildred Woods Bliss. The couple, who were noted philanthropists and patrons of the arts, purchased the property in 1920 to house their growing collection.

At the time, the estate included an 1801 Federal-style home, six acres of steeply graded farmland and a series of sadly neglected gardens.

HOW TO CREATE A COUNTRY HOUSE IN THE CITY

The Blisses had just arrived home from two decades abroad and were keen on creating ‘a country estate in the city.’ Upon falling in love with the sloping terrain of Dumbarton Oaks, they spent the next twenty years renovating the property. To help her transform the land into gardens, Mildred hired renowned landscape designer Beatrix Farrand. The project ended up encompassing both formal and informal designs and is today considered to be Farrand’s most ambitious work.

A EUROPEAN GARDEN WITH AN AMERICAN FLAIR

Beatrix and Mildred worked together to design and build an intricate landscape with a distinctive American flair while incorporating elements of Italian and English garden style. Some say that the women created one of the “greatest garden ensembles in American landscape history.” The diversity of styles allowed the garden to remain flexible and over time, it evolved to include new designs, plantings and ornamentation.

To preserve her vision, Farrand documented all her plants and the reasons for their selection in The Plant Book for Dumbarton Oaks. Completed in the 1940s, it remains the key resource for maintaining the gardens in the style Beatrix and Mildred intended them.

THE DUMBARTON OAKS RESEARCH LIBRARY

Then in 1940, the Blisses cofounded the Dumbarton Oaks Research Library and Collection to display their collect of rare books, documents, art and other objects accumulated during their years abroad. They subsequently donated the mansion, outbuildings and formal gardens to Harvard University (which was Robert’s alma mater).

In 1963, a Garden Library was added to the house to display Mrs. Bliss’s collection of rare and modern garden books. And today, the Dumbarton Oaks Research Library and Collection is a Washington, DC institute administered by the Trustees of Harvard University. In addition to offering fellowships, internships and exhibitions in Byzantine, Garden and Landscape studies, Dumbarton Oaks includes a Museum of Byzantine and Pre-Columbian art and a Music room that provides a venue for concerts and lectures.

In a 1940 letter to his wife Mildred, Robert wrote,

‘At Dumbarton Oaks you have created something very beautiful, very special both in the garden and inside the house. It will remain a monument to your taste, knowledge and understanding – a delight to all who visit it and a great resource to those who are fortunate enough to work there. ‘

THE GARDENS

Farrand’s 1921 design was built around a phased transition from formal to informal spaces, ending in a woodland landscape (also designed) in the valley below the mansion. The design included numerous ponds, streams and garden ornaments all of which provided focal points in the gardens.

Today, the garden staff continue to evolve the gardens, creating one magical space after another.

THE TOUR

A visit to the gardens begins behind the main house on the Arbor Terrace, a broad swath of lawn overlooking the lower gardens.

The terrace is bordered by stone walls and an arbor that, at the time of my visit, was covered in wisteria.

Descending a staircase flanked by boxwood hedges (the garden’s central axis), we passed a hillside of cherry trees (no longer blooming) followed by Crabapple Hill.

A pebble and flagstone path bordered by peonies and other spring perennials led us deeper into the lower gardens.

THE PEBBLE GARDEN

This beautiful space features elaborate stonework laid in the shape of a wheat shaft. It is surrounded by trellises of wisteria and low flowerbeds. Pairs of stone columns lend a sense of enclosure.

THE URN TERRACE

Everywhere on the property are small niches complemented with interesting architectural elements. We passed by this one on the way to the Rose Garden.The Urn Terrace functions as the transition from the Boxwood Walk to the Rose Garden.

THE ROSE GARDEN

True to form, this garden follows classical lines. Groups of same-species roses are laid out in geometrical grids accented by large and small orbs of loosely-clipped boxwood.

The garden is complemented by an antique stone bench.

THE FOUNTAIN TERRACE

This lovely garden can be found at the end of a flight of stairs further down the slope. As with all traditional flower gardens, it changes with the seasons.

Close by the Fountain Terrace, is the English-style Herbaceous Border, which stretches back up the hill, provides an expansive view of all its riotous spring flowers.

Lovers’ Lane Pool offers a quiet respite from all the color. The medium-sized garden features a shallow pool at the base of a small brick amphitheater bordered by bamboo.

The Plum Walk, with its identical rows of purple-toned trees, guides visitors further down the slope to the vegetable and cutting gardens.

Old espaliered fruit trees underplanted with spring perennials border the gardens.

Aside from the Arbor Terrace with its magnificent wisteria, the Ellipse is a standout with its double row of formally-clipped hornbeams at the center of which is a simple fountain surrounded by a moat. The fountain is original to Farrand’s design, although the hornbeams are not. They replaced a boxwood-lined enclosure planted in the 1920s.

Hornbeam Ellipse

Located at the base of the gardens, the mostly-green space is peaceful and serene with its geometric shapes and quiet reflecting pool. Dumbarton Oaks is famous for this aerial hedge of pleached hornbeams, which provide a sense of enclosure while offering tantalizing glimpses of other gardens beyond. A great way to finish off a tour of these lovely gardens.
