for thirty years (1913–43). Her most notable work was at the Dumbarton Oaks estate in the Georgetown district of Washington, D.C. for Mildred and Robert Woods Bliss (1922–1940). Her design was inspired by her European ventures, especially from the Italian Renaissance gardens, and consisted of establishing a sophisticated relationship between the architectural and natural environments, with formal terraced gardens stepping down a steep slope and transitioning to a more naturalistic aesthetic approaching the creek. In 1928 her husband accepted the position as the first Director of The Huntington Library (1927–41) in San Marino, California. They moved to California, but Farrand had trouble building a clientele in that state. William Hertrich had long standing dominion of the Botanical Gardens at the Huntington. The landscape designers Florence Yoch and Louise Council, and Lockwood DeForest Jr., among others, were already well established there. Her few projects came via friends, such as the Bliss winter and retirement estate, Casa Dorinda, in Montecito, California and the patronage of Mildred Bliss's mother, Anna Blakely Bliss, for the nearby Santa Barbara Botanic Garden project. In the Los Angeles area, she had several commissions each with astronomer George Ellery Hale and architect Myron Hunt. With the latter she worked on projects at Occidental College and the California Institute of Technology (Caltech). Farrand commuted cross-country by train for her eastern projects, such as the design and supervision of the Chinese inspired garden at 'The Eyrie' for Abby Aldrich Rockefeller on Mount Desert Island in Seal Harbor, Maine (1926–35). This was the era of the automobile, and in her designs Farrand applied principles learned earlier from Frederick Law Olmsted's drives at the Arnold Arboretum and the Biltmore Estate of George Washington Vanderbilt II. John D. Rockefeller, Jr. sought out and funded Farrand to design planting plans for subtle carriage roads at Acadia National Park on Mount Desert Island, Maine, near her Reef Point home (c.1930). Their use continues at the Park. Extant Farrand private gardens in the eastern U.S. are: the Bliss family's Dumbarton Oaks in Georgetown, Washington, D.C.; the Harkness summer home 'Eolia' in Waterford, Connecticut (1918–1924), now preserved as the Harkness Memorial State Park; and the Rockefellers' estate 'The Eyrie' in Seal Harbor, Maine. She also collaborated with Edith Wharton on landscape and garden design for The Mount, Wharton's home in Lenox, Massachusetts, which is open to visitors from May–October. Henry James introduced her to Theodate Pope Riddle,
